Hey MadMonk, To begin with, at least according to a few attempts, looks like the falling sounds can be corrected by setting oplemu=compat. The skypest squashing sounds are still "random", though. In more details: Well, I don't know if the report is relevant to the Keen 5 fuse issue, but there's …

I shall send my thanks as well. While one can use PCem (or another emulator) in order to have a hint of something (like a missing tone), actual hardware is what should better be used for reference. (Or as ones would say: Should be used 😀)

Ah, right, I should have written this: Apologizes in case someone is disappointed. For DOSBox v0.74, it doesn't matter which value is set for oplemu, be it default, compat or fast.

* POST EDIT FOR FEBRUARY 22 2015: It looks like this also has an effect on a couple of sounds from the Catacomb Adventure Series games (also sharing a lot of code with Keen 4-6). I've added a post regarding this. Hi all, I've had a suspect for awhile, that something is missing in the sound effect …

I should really say thanks for the patch in its current form! Sound effects appear to be proper in Keen1, Keen4, DN1 and DDave. Digger clone sounds aren't broken either (at least in the very first level). I have also tested digitized sounds in Ken's Labyrinth (as generated on a PC Speaker) and they …

Well, just to ensure things are clearer, here's what I've referred to (again for square waves): My guess is that the emulated speaker in DOSBox moves from maximum to minimum in zero time (and back). To compare, a real speaker, obviously, can't do that.

Ah, there's something I've forgotten to tell in my last post: The current DOSBox PC Speaker emulation seems to create accurate square waves (when "square wave" mode is used). That is, the emulated speaker is always on extreme top or bottom. With a real speaker, though, this is clearly not the case. …

Ouch. I've just tried with the Monkey Island 1 Demo and basically got the same artifact already reported. The prince of persia example is another clear case. Now, sure, an easy way to "solve" this is playing a bit with that condition added by ripsaw with the "cntr" value, by modifying the value. …

Source. Oh wait, haven't I already written about the quoted page? Well, time to do it! I should thank anybody responsible for figuring out the Inverse Frequency Sound format, as well as making the information available on the web; This is the basis for the attempt to improve the PC Speaker …

There's a bit more than a simple relocation; the added spkr.mode condition is what helps Digger Oh right I've missed it :happyhappy: Just tested the same patch but without the spkr.mode check. Looks like the digger fanfare sounds malformed again, although the Dave sound effects are fine. So, I …

Oh wow, a simple "relocation" of the original patch seems to solve not just the digger fanfare issue, but also the volume issues with these DDave sound effects! Good find Ripsaw! So, the problematic sound effects in Dangerous Dave are now being heard even more like the originals! And, there are some …

I made some modifications to PC speaker emulation a while ago (tried to fix popping). If you're interested in incorporating my changes, check out: http://www.vogons.org/viewtopic.php?p=158145 Hey, nice to see that you've attempted to solve another speaker-related issue. Truly, it seems to be a bit …

the end-of-level music tries to produce non-square waves by modulating the speaker cone position (changing the on/off values *really* quickly, so that the physical speaker doesn't have the time to reach fully ON/OFF status, producing intermediate levels). This is, in fact, *exactly* my guess for …

Thanks to anyone who has tried this or even just listened to the previously attached samples! edit button is in the top right corner of every post, although it is better to add new post as otherwise it won't be noticed. Interestingly, while looking for it, I've got to the text on the bottom-right, …

Hmm, looks like I can't edit the post. Alright lets add a new short one :) Basically, I'm attaching two recordings of sound effects from Commander Keen 1 for comparison: One recorded on the unmodified DOSBox v0.74, and the other one on the patched DOSBox. So, a few should now have a ready comparison …

Hey all, Before writing about its purpose, I'd just tell that a minor (experimental) patch to DOSBox v0.74 is attached. I've chosen v0.74, as the SVN changes often, while it also doesn't seem to differ where the patch is to be applied. Now to explain the patch's purpose: Some of you have possibly …

Hmm, there has been no reply here for some time. Guess I'll add mine :) While not playing CGA games so much (out of old DOS games in general), I should say this is a great addition! Originally available in Hercules mode, the patch adds the CGA variation. Playing with this feature can be nice for the …
