not a good idea ideas:

removal of phono input on home theater receivers

VCRs - DVD/VCR without HDMI have a monaural line in, which I just noticed. This means they don't connect to the cable box properly. With Denon receivers you need a VCR with an HDMI connector but they all had tuners, which don't work anymore.

For generations phono inputs on home stereo amps and receivers provided the RIAA playback curve. This was eliminated, now turntables have to get outboard preamps
and connect to AUX, destroying the vinyl revival.

soundblaster - Looking at DOSBox x, it looks like the MIDI configuration needed neither an IRQ nor a base address so there never should have been any MIDI configuration.
Weirdness - some Windows games had DOS executables that I don't remember having IRQ settings. I'm certain MOO II used an alternate audio interface for DOS with Windows.
Also, some games had secondary IRQ recommendations. Terrible idea that caused too much confusion.

Soundblaster 16 had a backward compatibility glitch leading Gateway to use off-brand soundcards such as Orchid. This problem led to a plethora of clones.

mt32 emulator - doesn't work as provided therefore it effectively consistently fails to perform. What was really needed was an Mt-32 soundfont which is now available from Awave. That's what should have been available at the same time as Utopia Live! In the old days. If you want legacy gaming support, the best bet is a Roland CM-500.

DOSBox - the decision to ever include a soundblaster style MIDI synthesizer with this software was noise pollution.

VDMSound - consistently fails to perform

Microsoft Editor - this improved version of Edlin was unnecessary. Edlin excelled at replacing autoexec.bat and config.sys with previous versions.

epic fails - a couple of Windows ports did not go as well as they should. In the Kilrathi saga, it's the IFF system when flying captured Dralthi.
Space Quest Collection - 2006 and a Windows port where the Saurian Skull Droid is inescapable.

Also, the industry never settled on what hardware it should use to transfer the MIDI music to modern audio. It looks like it should be the Edirol SD-20 for sound canvas and the Edirol cm-32l for LAPC-I.

cassette players - given what happened with Dolby expiring, this technology is really gone and it doesn't look as if anyone particularly misses it. I have used a microcassette recorder that wasn't my own. Could that have won the day? Delicate sound of Thunder clocks in at 104:08. So, because of those Pink Floyd live albums, microcassette wouldn't work. Ozzy Live and Loud at 117:16. Beast over Hammersmith 95:31. Live after Death 98:09.
How the West was Won 150:27.

Another gripe, Pink Floyd is labeled "progressive rock." Wasn't the term once "avant garde?"

Kenwood car stereo speakers - I once heard a 4 way $100 pair that had better sound than anything I have ever heard. They're gone.

Radioshack mice had drivers that could be loaded by the config.sys file, unlike every other mouse driver that could only be loaded into the autoexec.bat file.

removal of Windows MIDI control panel
Yamaha pulled the SW1000XG off the market when this was done. Symbolically, it means neutered Windows can't run synthesizer PCI cards.

invention of C sharp
C++ is the obvious choice for video games and even TCP/IP is doable in C++. WPF does not look as good as MFC.

cell phone - the batteries take much too long to charge.

discarding digital audio disc - this format was standard audio and not in "advanced audio engineering" zone.

The Turtle Beach Santa Cruz - this thing was the basis of audio support on the original Xbox so it does matter
problem - the pins on the internal S/PDIF connector were backward
problem - the microphone connector provided 3.5 volts of bias instead of 5
problem - the red S/PDIF output was defective when used for stereo LPCM.

Oh, yeah, the m-audio revolution 5.1 had the left and right reversed on the headphone output

this reminds me

Altec Lansing ADA 890 - the failure of the quad mode is a technological embarassment of epic proportions
https://www.dell.com/support/home/en-ca/drive … driverid=r37890

the dismissal of Sensaura makes it look like there was no competitor for the Xbox to reach out to. They still have a wikipedia page. Sensaura also could have been used for other virtual surround.

FF7 and FF8 port to Windows

If it weren't for these games using MIDI, I swear MIDI support would have been seen as pointless on gaming soundcards and the synthesizers would have been dropped
and the prices gone down before the next generation of Soundblaster, which was the Live!, which came out in a month.

Use of Soundblaster Live Value! This card came with Gateway computers and is I couldn't get the 3d audio effects to work, it is a budget version of a Live! Also, it killed Vienna soundfont studio.

Multichannel audio on onboard audio. This caused confusion with the soundcards. The current generation of Soundblaster doesn't use EAX, and without that who cares?

Allowing games to provide surround sound - this totally took away from the use of the soundcard, led to much confusion, and the demise of EAX.

Dismissal of Groove Music - it's the only player that would flip the image to the album artist.

preset tuning - this is relevant to very old cable ready VRCRs. It was originally 13 channels when universal cable VCRs came out it was changed to 14 channels. It was an archaic feature still available. The feature can be broken.

Beyerdynamic MMX300 the instructions have the adapter for PC gaming and game consoles backwards
Audio Technica ATH-AG1X has a short circuit on the headphone and the microphone connector

Polk Audio db Series defunct. These speakers were shallow enough to be drop in replacements for OEM speakers. They were good. I miss them. This puts an
incentive to get a speaker upgrade when you buy the car. Polk had more expensive speakers than that, but after looking at it I lost interest in anything else.

Sparkomatic car stereo speakers dismissed from market - cheapest good sounding car speakers. I forgot them. Very good. Have had them and Polks.

Universal remote controls - I've bought them from Best Buy and Crutchfield and they do not work with subtitles.

The loss of HP laserjet paper.

they maintain an RF connection despite the fact that it is completely obsolete.

Adobe Photoshop - used to be able to acquire from a scanner. It also had OCR. Functionality replaced by PaperScan.
The decline of Photoshop makes me wonder what led to the end of Fedex Office.
AppleWorks dropped - must have had an effect on their bottom line
Daisy Wheel Printer - missing image
Scribe - missing description
Apple gameport - rather nice really, and has 3 rows of pins, more than for the PC. I think only 14 pins are used, to prevent it from becoming a MIDI adapter. I think it is 21 pin places.
FedEx Office - in addition to apple related mischief maybe they could offer photo lab services like printing an image on photo quality paper for storage in a photo album or a photo journal.

unrelated to apple again:
OpenGlide - fail with Carmageddon II, try a DirectShow window, which would require rescaling the overall resolution because the resolution would probably come out much too large.

Nexxus - online periodical search is gone.

Element Cable - blue, custom length power cables. Yes, you can pick up long length cables from Guitar Center or the like, but it's not the same thing.

Apple's fundamental error: In operand zero - the indication of a bad connection. Arguably, there shouldn't be any indication, just a
bad connection when there is a bad connection.

HDTV - the default HD size does not display the entire image - annoying

DOS - batch files do not work without the ".bat" extension.

DOS - inclusion of Microsoft editor was unneeded. Edlin was fine.

Also, the wikipedia is indicating that they are trying to use the DI-9 Mac Connect with the 8 pin LocalTalk? As Bill the Cat once said,
"tthhhpppppttttt."
Also, even if there were to fit a square peg in a round hole, connecting a printer to a network doesn't do any good unless the printer is
network ready. If not, the printer won't know what to do with a network signal anyway!

The wikipedia has lost so many pages and left so many pages out!

wikipedia: removal of page dedicated to cm-32l. I have used one! They didn't skrag this model, did they? This could ruin keyboards.
Electrical specifications of MIDI metasmatized. It is like they are confusing MIDI cables for audio cables. This is loss of technology.
Amplifier - switched mode power outlet could be mentioned
history of cable TV - 6 phases and 4 output modes. I checked and I saw that some 4k content has already been broadcast
VCR - could mention auto tracking
Also, forward and reverse scene selection which is also referred to as forward and reverse picture search
one touch recording
auto clock
smart channel mapping - this is a later feature that involves a zip code and I never have encountered it
radio receiver - could mention FM automuting (this subject is only covered by JVC automotive head unit manuals online)
Also, analog AM has the problem that pin dot pre tuning drifts. It should have been engineered as mono only.
Analog FM because automuting is a nuisance should have been engineered so that automuting would be redundant.
Soundblaster 16 - bad image
Soundblaster 16 Waveffects - bad image
Waveblaster - bad image
Soundblaster Live Value! - a very important version and distinct on the creative support site, should be covered.
3.5mm jack - bad image
gameport to MIDI cable - how about an image of one
auto reverse - this is now an entry in Merriam-Webster online. Pertains to audiocassettes. Basic, really. It had 3 submodes.
One of those submodes is standard play. When in standard play auto reverse is off and playback falls back on the bidirectional replay capability
The other modes are auto repeat and auto reverse.
bidirectional replay capability - a closely related feature to auto reverse
160kHz Super Bias Electronics - this used to be described on the wikipedia, it's for cassette players, does this feature take the place of an MPX filter?
MPX filter - attempt to repress the bias frequency altogether. Found on PIoneer players.
Nakamichi Automatic Azimuth Correction - this could easily be taken as the best brand if it weren't for super bias. I suppose it's an interesting feature I found while googling
rewind auto play - an audiocassette feature I never knew about until I read a description of a Pioneer player
automatic distortion reduction - Akai feature
spring loaded tape holder - Kenwood feature
bias frequency should be a searchable selection under Tape bias. Maybe it should be called pilot tone?
Master tape - there is an entry, but the information on tape bias is missing
remix - a remaster is described, but not a remix
Scotch - I used to use this brand of video tape. I didn't know they made audio cassettes.
Axiomatic bias frequency - needs to be defined on the wikipedia.
Universal remote control - doesn't describe common controls such as play, stop, and subtitles.
RIAA equalization - no clear cut terminology such as RIAA replay curve well defined
fader - for consumer electronics the definition for every car stereo is missing.
device driver - no discussion of where to download for your interested technology
Dolby Virtual Speaker - still has a FAQ with Cyberlink, ought to have a wikipedia page.
HRTF needs to be related to psychoacoustics on wikiepedia
Defunct companies ART (Advanced Research Technology) and Digitech don't have wikipedia pages, I used to own some of their gear
Turtle Beach - I've bought this brand and they carry their products at Walmart!
network ready - found the term on the web, but not the wikipedia
photocopy - defined in the dictionary, not the wikipedia
Creative Wave Blaster - nice page but it needs a subtopic for the connector and not just a pinout.
Digital Audio Extraction - its for playback, not just for ripping
LaserDisc - Pioneer was the first to call the format LaserDisc but Sony produced Laservision with CD quality audio in Japan before Pioneer did. Yes, Iron Maiden's Live after Death is an outlier that made me wonder about Pioneer's dominance. K, I found something from Pioneer without digital sound, it is still called a Laserdisc. The original technology is called MCA Discovision according to the wikipedia.
https://www.lddb.com/laserdisc/31502/96LS-200 … Slavery-Tour-85
The LDDB clearly indicates that there were 1984 Pioneer Laserdisc that had digital sound. Neil Young for instance. This was not at all clear before - they've done a lot of work with new images and details.
variation effects - companion to reverbation.
lack of description of MIDI adapter cable
stereophonic sound - really needs a mention of stereo audio cables.
MTV - a discussion of their implementation of stereo sound
output level - a description of the output level for headphones and speakers should be distinguished from live level
Blue Screen of Death (BSOD) - good entry, but it needs something about bad or missing ntoskrnl. That error leads to hard drive failure. The modern version of the error in Windows help is
Windows could not start because the following file is missing or corrupt:
<Windows root>\system32\ntoskrnl.exe.
Please re-install a copy of the above file.
This is not good enough, it is a hard drive failure.
mobile phone - no acknowledgment that a cell phone run on electricity
service carrier - a company that manages a cell phone service account
account - cell phone, there are 4 account types listed on the wikipedia, obviously cell phone account needs to be one of them.
swap(ping) - cell phones can be swapped. No explanation here.

auto preset - this is relevant for older, cable ready televisions and universal cable VCRs. Also,
auto tuning - which is an older, slower version of auto preset. Auto tuning was 103 channels, auto preset is 99.
channel auto set - This is the VCR equivalent of auto preset for universal cable VCRs. 99 channels.
auto tracking - relevant for VCRs
auto fine tuning - relevant for older televisions, it's a single button
manual tuning - at the time that TVs had auto tuning, I remember 115 channels available for manual tuning. At the time of 13 preset channels on VCRs, I remember 13 channels available for manual tuning. Presumably, for
UHF - channel 14 to 103 channels on the dial
TVs the number of channels went down and for VCRs it went up.
cable converter box - missing "surround sound" which is a standard feature on all modern boxes, but this had not always been so
Ctrl+Alt+Del = different effects on different systems
printer paper - dot matrix printers use continuous form paper, they still make it and they used to make a type that peeled and was annoying. Ah, carbonless continuous paper.
LA synthesis is a form of sample based synthesis and this may or may not have been mentioned on the wikipedia before.
FM radio - analog FM used 300 ohms as the standard impedance. I remember this from a Kenwood tuner. HDFM is 75 ohms, like a digital audio connection.
Gator Radio Network - deserves props.
turntable strobe - this is a device that Crosley used
stereo indicator - for Sony VCRs
terminology - save disk
terminology - boot disk
as a follow on, a description of the PROMPT command would be useful
terminology - remodulation

Visual Studio 2019 appears to have dropped MFC applications. And Visual C++ has dropped the DirectXSDK. So Visual C++ is useful now neither for desktop applications nor for video games. But I don't have the professional version.

things that were not done well enough or done on time

textile printing - the more advanced technology is laser screen. That's a lesson from preschool.

CD players - maybe they could have waited for a 48kHz sampling frequency, then there wouldn't be dedicated resampling Integrated Circuits.

USB should have been available as soon as the PCI bus was available and no game port should have been used anymore

synthetic stereo - Kenwood gimic for monaural VCRs. Yes, it improved the sound but it confused people. It might have worked had it made the left and right channels balanced.

Images on the wikipedia now resize when selected, but this should have been done from the beginning.

Roboform - there is now a print function. Having that before would have saved me a lot of grief.
Also, having it web based would have saved me a lot of grief.
Also, never deleting the MRU menu would have saved a lot of grief.

graphical widget - now defined on the wikipedia

The kernel was once a dll and is now an executable. The kernel is an entirely separate process. Now? Dumb and dumber that could have done a long time ago. This should make it much harder to crash Windows.

CassetteDeck.org - there was an older site with more complete information than this, the reference unit is the Sony TC-WA9ES

The loss of compact stereos. The best brand was Aiwa, I used a Philips back in the day. They are back with Denon, but they've been away for a while.

35 mm slide scanner from Plustek - has come out after nobody makes analog cameras anymore. You would really need an analog camera to get the proper picture. I have found some old 35 mm slides and they do look marvelous. I think this technology has renewed interest because of AP art classes producing a lot of 35 mm slides. At least, that's what I got out of reading their description. Bring back the dead? Another reason this field could use some work is that cameras don't use lossless files, png or tif are what I've used in the workplace. Preferably png (lossless compressed, under ISO standards). Now that I look up the availability, forget the Plustek scanners. Wait, looking at the wrong models. The models that use Silverfast and produce 48 bit color do exist.

satellite radio

They did not choose an adequate modulation scheme to get the bit rates they needed. They really needed to broadcast at 48 kpbs to get above the hard of hearing
audio fidelity threshold. At these bit rates HE-AACv1 is good enough, they don't need to wait until HE-AACv2. In fact, at 56 kbps, the music is ameliorative to human hearing. That's also the bit rate at which AAC encoders switch off SBR.

HD radio

First off, the bit rate is supposed to go up when analog is retired. What about surround sound? A modulation scheme to allow for AC-4 broadcast of 192 kbps surround sound is possible. Remember, it's relatively low bit rate material so AC-3 or DTS are right out. Then do we want to compromise surround sound with the fader bucket? If no, to broadcast virtual surround you need some sort of psychoacoustics. Dolby, DTS, QSound, or even Creative Technology could do this. I suppose the default would be QSound.

Which is where demise of DVD-Audio comes in. That's the source they needed for surround sound radio, and without that we have multicasting of stereo instead. The sampling frequency was 96 kHz v 384 kHz with SACD.

Surround sound music implies a remix of the original music. It has been done.

The thing is, archiving an .mlp file which is what's on a DVD -audio involves revealing the secret key to the best encryption system in the world. So maybe the better idea would be to use digital audio disc in stereo, and encode that in AC-4 straight from a 24 bit/96 kHz source. I'm sure dbPoweramp could be easily adjusted.

The thing is, the #2 and #3 home receiver makers (McIntosh and Denon) are ignoring HD radio. If they hadn't ignored HD Radio then I wouldn't have this thread. Krell, the top brand is meant to be used with Magnum Dynalab tuners.

I see, they want you to buy the Sangean HDT-20. It's an HD tuner.

Also, I forgot the problem of HD-AM being low bit rate. Advanced Audio Coding has a speech profile. Whatever happened to HD AM, it's been changed and I have no idea a realistic bit rate.

Betamax - the problem with this format is not its image quality. What happened was that Beta went from a format that rented the best movies to a format that rented the same titles that VHS did, while charging a higher price. Betamax carried movies from Cinemax, which in the early 80s were better than HBO. When they started carrying the same insipid titles everyone else did, they disappeared. I remember looking through the premium channel movie guide for cable and all the interesting movies were on Cinemax. I remember Betamax tapes had blue cases and were more popular some of the time I went to the video store - a name I can't remember! We did eventually get HBO for a while.

That is not to say VHS was a terrible choice. SVHS was better than Super Betamax. But now that I am reviewing the SVHS page, not as good as ED(extended definition)-Beta. And JVC tapes, which I had to order, were T-210, which is long enough for a football game. I did find something too long for VHS, Hamlet (1996). Also, Lawrence of Arabia. Ben-hur. The Ten Commandments, and the Fall of the Roman Empire.
JVC owns the technology behind VHS.

A little later than it should have been - Klipsch Promedia dumps BASH amps in favor of toroids. A little late. It comes after they issued a Bluetooth version of their speakers.

bulletin board technology - some things that are improved that could have been done better in the first place
1) list of posts made on a bulletin board
2) copying and pasting formatted text into a bulletin board (the formatting used to SNAFU then developed into FUBAR, and now is fine)
3) attaching images into a bulletin board

auto clock on VCRs. An old feature but it would have been nice to have had it sooner.

19 micron head technology. This would have made auto tracking quicker.

high speed internet - needed it before I started college

HD TV - the default image size is zoomed. This default setting is no longer available. This should have done from the beginning.

TV/Video input on the receiver. Dropped. Thank, goodness.

Cell phones with phone numbers on the outside.

MSDOS 7.10 should have been available with Windows95 from the beginning. It made Joliet file naming awkward. Remember how DOS named the program files folder progra~1? And nobody wanted to use the command prompt any more? They got rid of command.com and have replaced it with DOSBox -X but it isn't quite the same thing.

DirectShow - the most fundamental of the advanced APIs this is the one needed for movie playback and browser plugins
Also, DirectMusic - this should have been available with product launch so high res music worked on Windows
DirectInput - not available until XP it would have meant controllers could work on the PC and the original Xbox.

Something that used to work better and has been dropped - associating a URL with a mirrored image. Support for this is gone.

Some good technological decisions

1) DOSBox, especially including a Tandy mode with the speaker
2) Windows included a default softsynth. This means the Windows MIDI interface is always there and is undeniable and there is something to check against.
3) the Santa Cruz could use GM.DLS
4) Wikipedia page on MIDI now puts the years back far enough to be real, the Yamaha DX-7 (1983) had MIDI connectors and has been in music videos.
5) the pinout of the sync DIN on the wikipedia
6) retiring the VDM from Windows
7) Soundblaster MIDI synthesis is no longer emulated in DOSBox.
😎 Microsoft Office supporting the Mathtype plugin.
9) The MathType plugin supporting teX characters. Sorry Unix.
10) Awave Studio - lets you take your MIDI bank and change formats
11) By God, the Roland Integra 7 supports DLS after all
12) Polk Audio home stereo speakers. They really have good price/performance
13) USB hubs on flat panels - I plug my keyboard and mouse into my monitor. Better than wireless.
14) Denon is back, with better receivers than Onkyo or Integra.
15) elided - Visual Studio 2019 Community version appears stripped bare for C++
16) Soundcards with dedicated headphone outputs
17) ImageWriter - the only printers for Apple II that were any good are still available on ebay. Oops, the wikipedia has some good info, before ImageWriter there was Scribe. I remember having one of those. There were LaserWriters I couldn't afford and Stylewriters that came out in 1993 that I didn't know about.
18) Adobe Incopy - it integrates with InDesign so it gets MathType too
19) musician's earplugs
20) Microchip Technologies makes inexpensive Digital Signal Controllers, like $5.13 for a dual core.
21) Microsoft bought Ada and changed the syntax so that polymorphism is intelligible. Now I understand that you can't pass user defined types by reference. I never have used polymorphism is Ada and I never figured out what the limitation was before GNAT dropped it.
22) Tinactin, Lamisil, and Neosporin which are fighting my croch rot.
23) Yamaha - THX certified mixing consoles has increased interest in their recording studio speakers which are becoming an industry standard. The MSP7 are THX certified themselves.
24) Apple iWork - now that I look into this, it lives and is freeware. I haven't tried it, but I bet it's better than OpenOffice. Yech. Oh, it's Mac OS only.
25) DAE - digital audio extraction - not introduced until Windows 98 second edition. Takes the place of the internal S/PDIF connector on a soundcard.
26) RDSC data - forget HD radio for a little bit, RDSC data allows listeners to check artist and song title and figure out which songs are the ones they've always hated and send secret messages to the DJ about what they do and
don't like
27) Description of tape types - has been there a few months and I didn't know the search starts with "compact cassette" which is what audiocassettes were technically called
28) double cylinder deadbolt
29) fax function in multifunction printers - kiss analog fax/modems goodbye as well as attendant software, such as BVRP phone tools.
30) dumping analog TV and digital cable that isn't high definition. About time. Could have been done before Battlestar Galactica. This means that the TV ANT has nothing to tune to.
31) Dumping the MC v MM discrepancy in turntable cartridge terminology.
32) Crosley is back in the turntable market. Had one in the day and loved it. The next step up for consumers would be Audio Technica. Numark does DJ turntables along with Reloop. The Numark HS1 is a false stylus. Gemini is the brand everyone uses. Les Enterprises makes cheap diamondhead cartridges. MoFi (mobile fidelity sound labs) makes the best cartridges I have seen or heard about. Supposedly there are MC (moving cartridges) out there that are even more valuable.
33) Blue jeans cable RF cables - they fit easily unlike the cheapest RF cables and the gold is on the inside of the connector, so there is nothing making them obviously ostentatious.
34) screen resolution. Believe it or not, the way the science comes out the resolution for HDTV was chosen so that the aspect ratio could be flexible. Different aspect ratios for computer, TV, and I think microscope.

Last part:
high voltage technology
Something we need to do - for the sake of picture quality everywhere - is jack the voltage up to 512 volts for our homes. If I'm not mistaken the Sony standard is to withstand voltages up to 513 volts. Everything should still work fine. We need 512 volts for high quality DLP (which may be projected) and 500 volts for high quality LCD (the contrast ratio is limited). For computers, 35 volts would liberate FPGAs (which appear to be defunct) to do resampling to 96 kHz without overheating, allow low current architecture in CPU design, and I'm sure some other benefits. We don't need anything more than 5 volts on the PCI bus. Which is where we are.

I may point out that voltage at the source is not necessarily voltage at delivery. You can set the voltage at the power plant different from what's in a home. The power lines themselves are extremely high voltage.

35 volts would probably work better in a car. And a plane. And a soundcard because of the headphone output.

There are thermal minima at 14,000 and 3million+ volts. This is known, however, when the power lines are pushed to above 3 million volts the power sub-station here in northwest Florida starts to fart out. We can't get our
power grid up to the 3 million+ volt thermal minima.

Now I remember, it may be risky, but the universal thermal minimum is at 532 volts. Useful for cryo experiments. Optimal refresh 52.4 Hz IIRC. Or 52.394 Hz.

K, from what I remember, to get Plasma screen to work properly, they reportedly need 512.1 volts to get them to be bright enough. I think that number is ghey, and some sort of falsification. Like, get it to work without the .1 volts. Debatable.

Also, the impedance for speaker matching IMO should be 300 ohm. Both speaker and amplifier. For home theater. For guitar speakers, it may change the sound so radically I don't know. Everyone likes their 8 ohm full stacks.

Eight ohms is fine for line level output, which makes me think someone got the spec backwards long ago when they started making home stereo equipment.

75 ohm is supposed to be for digital audio and analog video connections.

These impedance numbers are supposed to come from transmission line theory, which I never understood. Because I don't think it was taught well. Anyway, it's not just high frequency (digital audio/video, analog video) that need to be analyzed, it's anything output level. Amplifier and headphone connections are high current enough that transmission line theory needs to be used. The analysis which I read somewhere is that at 8 ohms a lot of heat is generated on the cable.

yin and yang - Breeder reactors. As described on the wikipedia the technology is impressive. Used quite a bit in France. Do we really need it? They've adapted nuclear cooling towers to coal and with geothermal I don't see why we need nuclear. I've seen wind farms too. Unless we want to recharge out battery operated Enterprise for another round of battle with the Klingons I don't see that we need anywhere near the electricity that a plant like this is capable of generating.

losttech PTY - program type. This is the indicator in the RDS data that tells you the genre of the station. It may sound boring, but now that I have accurately observed a list of radio stations available on my tuner in a Mitsubishi Outlander I can see how this bit of information is sorely missed. Generally, you get the frequency, optionally station identification such as "99 rock" and then some indicator of HD status such as "HD 1" or "HD n" where n can be up to 4. Typically, though, they seam to broadcast HD FM in groups of 3.

Also, there was supposed to be a way to search from station to station for a subset of genres, divided into about 8. I think it was supposed to be a separate beacon or something broadcasting from each station. Between this technology and RBDS I think HD Radio was born. I forget what the technology was called.

Also, subwoofers. The crossover frequency is based on HRTF functions or something. I mean, it is based on the notion that we can't hear stereo separation below 80 Hz. Bah, humbug it is too high. It should have put at 55 Hz which is below low 'B' on an alto guitar and matches some Celestion and Electrovoice loudspeaker designs. You don't want your fundamental tone coming out the subwoofer if you are a guitar player. That's cheesy. If you really want to be scientific about this, the question would be which crossover frequency is the most ameliorative to human hearing? I don't know.

If a speaker had a resonance frequency of 52.394, maybe it would minimize excursion, which is the safest design, and simplify design of the voice coil. If you've forgotten, that's the suggested frequency for the power grid.

Also, since I regard the transmission line theory that I only partially learned (I realized you can model an "extremely high impedance" as an open circuit) the way to model impedance transformers would be as an intermediate impedance between two mismatched impedances. For those who find that confusion the point is that cable designs have intrinsic impedances for AC signals. The two numbers that fall out the most are 300 for dual wire and 75 ohm for coaxial.

The only other thing that transmission line theory needs to explain is RG59 v RG6 cable. RG59 has greater capacitive losses (its more flexible) and is therefore less suitable to broadcast television that RG6 cable. That's the part of the model the transmission line theory is trying to look at and generally doesn't illustrate it very well.

Something else I do know, that has nothing to do with my experiences, you need a phase locked loop to handle asynchronous timing. Which makes me wonder if the quest for a true RTOS (real time operating system) is even necessary.

Also - superconductors. First off, if you think electromagnetics is hard. Wait until you see solid state physics. The theoretical understanding of superconductors is beyond engineering into pure science. I will say, isquaredR losses on the transmission lines should be minimal. I didn't think you can use superconductors in the transformers! that's where I'd look to put the. When you convert from one voltage to another you need a transformer to do that, and they waste a lot of energy. That's where the losses occur other than sheer utilization. The reason we have them is to keep the system modular. That way the transmission lines are not limited by the mere 120 V in your home.

I just realized, superconductors can't make progress because transmission line theory is falsified.

Something else I didn't think I'd bring up. Cell phones, wouldn't it be nice if our car stereo were a cell phone? Then Bluetooth on a cell phone would be for headsets. Audio streaming? I prefer a USB port and an AUX port. Maybe I sound like Grumpy Smurf.

The wikipedia does not say anything about safeties on guns. Oh dear.

Was it?

The Turtle Beach Santa Cruz was based around the CS4630 chip . AFAIK, the Xbox first gen audio system was similar to (or based on or the predecessor to) the Nvidia Nforce .

My Denon 1500 has a phono input. So they do exist...
I personally am very wary of the death of physical media in general.
My kids "forced" me to get amazon prime and the number of times a movie they want to watch all of a sudden costs something is very annoying.
Also the surfeit of streaming services means you are constantly taking a hit on cash flow.
I live in Europe but have many DVDs and Blu-Rays (how I wish region.-free HD DVD had won ) and even finding a decent player that can play all formats and regions is getting difficult. It is practically easier to buy a device in the US and have 2 devices than finding one that is easily made region-free. (I am aware of the many devices out there that have been chipped or modded to play it all, for some strange reason I like using codes to "unlock" things more....

My son wants to build a PC and one of my main devices (a video capture device) requries a firewire connection. The mainboard recommended to me doesn't even have PCI slots! (I am sure there are some out there I just haven't looked)...

The future used to look so much better...

The easiest way would be getting a PlayStation 3 - put HAN (or HEN for later models) on it and install Webman Mod and voila - you've got yourself a region-free DVD and BluRay player.

Blockbuster. They are technology. Blockbuster started to go downhill when they said they couldn't rent game consoles anymore.

Nobody talks about standard batteries being substituted by (not standard) rechargeable ones?

I still have digital cameras that uses AA batteries and a mp3 that uses AAA... but I know that my (better) Philips mp3 will be junk when the battery fails.

I have traveled across the universe and through the years to find Her.
Sometimes going all the way is just a start...

I like Rayovac batteries by the way.

DTS owns Ibiquity which owns HD Radio. DTS Neural Surround I suppose would be the choice? Doesn't have the same ring as "broadcasting in Dolby". If I were an announcer saying "broadcasting in DTS Neural Surround" it just doesn't have the same ring to it. Also, the only formats with surround sound are DVD-A and SACD which are advanced engineering audio formats which have never caught on that well. You can't rip those formats. Wav file does have 5 channels in it, but is limited to 96 kHz and SACD takes 384 kHz. Can the wav file be cranked?

Neural Surround has a stereo source with surround sound playback. Maybe that would be interesting for home theater systems, not so much car audio. The intent is to broadcast in low bit rate (compared to CD) and do ... geez I've been up all night with jock itch. Well, basically a 100 kpbs ac-3 stream. That's a bit low. What's the encoder? Maybe AC-4? It depends on the bit rate. Nokia would lose their licensing fees.

Also, tough actin' tinactin. When you are really infected you need this stuff.

I do remember, when they drop the analog broadcast the digital bit rate will increase significantly.

Canon was the only legacy camera company that handled the great AF transition of the 1980s well. Minolta abandoned their old lens mount they used since 1960s but they still used mechanical focus coupling and mechanical aperture control. Nikon and Pentax both kept their old lens mounts which seemed a good decision at the time but even now the majority of Nikon SLR lenses still use the same old mechanical aperture control. Because of this, Canon is the only legacy camera company that has full and seamless compatibility between their SLR mount (EF) and their mirrorless mount (RF), and the adapter they use is just a tube with a bunch of contacts. In comparison, Nikon's expensive FTZ adapter is a useless piece of junk that is only compatible with a fraction of their lens catalog.

That's actually a plus. I have various old lenses from the 70's and 80's and I can still use them on my current Nikon camera. Even the manual lenses that lack any autofocus functionality.

Bad for Nikon, because they don't make money if people just keep their lenses for decades, but good for me.

not a good idea ideas:

removal of phono input on home theater receivers

For generations phono inputs on home stereo amps and receivers provided the RIAA playback curve. This was eliminated, now turntables have to get outboard preamps
and connect to AUX, destroying the vinyl revival.

To be fair, many audiophiles would rather have dedicated phono preamp than supposedly mediocre phono preamp in an AV receiver.

Never thought this thread would be that long, but now, for something different.....

From what I have seen of some mass market, modern and inexpensive turntables, they tend to have an integrated pre-amp, uneven platters and are bundled with extremely crappy cartridges that require something like 9g of VTF .

Full disclosure: I am not a vinyl lover in the sense that I have no nostalgia or affection for the format's limits/flaws . I prefer my sound to be as close as possible to the studio masters . That said, I will use vinyl if something I want is unavailable on a lossless digital medium (theoretical scenario so far, but I do have a Technics SL-Q2 ready for that eventuality).

Well, for most current Nikon cameras this compatibility is very spotty - they can't even meter properly with manual lenses. In fact, you get better functionality (e.g. aperture priority and full matrix metering mode) using manual Nikon lenses on Canon cameras, unless you pay for one of Nikon's top-end bodies 😁 Nikon's "old" AF lenses that don't have the built-in motor also autofocus only on select Nikon cameras.

In contrast, every Canon EF lens works perfectly on every Canon EOS camera. Canon was so prescient that they even included distortion correction information into the EF lens protocol. You can use the earliest EF lenses (released in 1987-1995) on modern Canon cameras with full functionality (AF, IS, automatic distortion correction). There are no Nikon lenses made in 1987 that work with full functionality on all current Nikon cameras.

I'm heavily into vinyl and there are literally no decent new turntables under approximately $1000. And if somebody is willing to spend $1000 on a turntable, they probably can afford a quality phono preamp as well.

Now I see, after receiving surround sound in Dolby, the head unit itself can process DTS Neural Surround for 2 speakers.

Sure you can do bit-perfect DVD-A rips. That 96 KHz @ 5.1 is a limitation of the DVD-A spec itself. Even MLP-compressed 5.1 at 96 KHz can creep up to around 8.5 mb/s. 192 KHz would be twice that, which is beyond what a 1x DVD player can manage. That's why 192 KHz is only available on the stereo tracks (which, btw, rip just fine to 192 KHz WAVs). Compress them with FLAC, and they're half the file size.

I believe BD-A can do the full 192KHz on 5.1 tracks.

I don't own any SACDs, but I believe they can be ripped as well. They wouldn't be bit-perfect rips like DVD-A, due to the nature of the beast (SACDs use a DSD encoding scheme, which would have to be converted to PCM, whilst DVD-A is already a PCM based format), however Foobar2000 can convert DSD to FLAC.

I haven't subscribed to any kind of TV service for years, but I remember most stations broadcasting AC3 at 384-448 kb/s, which is the same as most DVDs. That was during the bad old MPEG-2 days; they've probably switched to E-AC3/DD+ at a lower bit rate since then. However, E-AC3 is twice as efficient as regular AC3. Netflix somehow manages to fit decent sounding 5.1 @ 192 kb/s! I've actually felt Netflix content hit around 20 Hz (the pressurized room and pant leg flapping sensation is what gives it away). E-AC3 is a damn efficient codec, probably even better than AAC in that regard!

I have an old Yamaha 7.1 HTR-5960 A/V receiver with all kinds of old inputs and it still works well today.

Look at this on eBay

I also have a NEW 65” 4k TV ( Vizio M-658-g1 ) with great picture and every input/output you can think of.
It works great.

A used Technics SL-1200 is about half that in US dollars and I have seen them locally for much less . Even if you need to pay someone to lube/clean it, it's still a better deal, IMHO .

I'm currently running a used setup that cost me over €2.5k, and I would have to spend close to €10k to get something new in the same class, so yeah, used is the way to go in this case.
