My dad and I operate a local radio station. When we were setting up the hardware we initially purchased two Sound Blaster Audigy Rx cards, one for the main audio playing computer (as output only), and another one for the Studio-to-transmitter-link computer (as an input only card). For our studio to transmitter link we stream the audio mp3 at 224kbps over the Internet (we can't go PCM since the connection at the transmitter is limited to 1.5mbps and it totally messes up when I switch it over 😖 ). When we were using the SB cards the audio processing took place at the studio, before we sent it to the transmitter. The audio ended up being the worst quality you've ever heard. It was so bad it was painful to listen to. It didn't just sound compressed, it sounded like I was listening to a speaker dunked in a fishbowl and playing at 12000 Hz. Even after disabling all audio processing it was still horrible.
So we gave up and replaced the Rx's with our old Audigy 2 ZS's, which is what we had lying around from a previous radio station experiment. These sounded a bit better, but they still had that "fishbowl" quality, no matter what I did to the settings anywhere.
After that we switched all of the audio outputs and inputs to some bare-bones DAC boxes, which seem to give the cleanest, sharpest, most unadulterated sound I've ever heard. With those installed it sounded great, and after moving the audio processing to the transmitter site it sounds even better. I dare say we now have the best-sounding station in town.
So my question is this: what are those new SB's doing to the sound that causes it to sound so horrible when compressed and sent over a stream? They sounded okay when listening over headphones, but they didn't sound as good as the DAC's. Those DAC boxes sound awesome, and they're just bare-bones DAC's with no extra features or anything. If I used a retro PC with an SB16 or even an AWE card, would I not have this problem? I'm still using one of those Audigy 2 ZS's in the STL computer as a recording device, for recording live shows, and it seems to work fine.
I don't want to switch back to Sound Blaster cards, I'm just wondering why this happened in the first place.
