I've noticed that BYOND greatly reduces the quality of .wav files on playback, and was wondering if this was a known issue, and if it was being looked at for the coming upgrade.

I have made a cool little intro signature sound for my games, and reduced it to 11khz 16-bit stereo. It was still a bigger file than I wanted it to be, but it sounded so darned nice. But then when I played it back in-game, not only was the quality much, much lower (8-bit, 8khz?), but it actually played back in mono.

If I knew the exact sample rate and bit depth limitations, I could at least optimize my sound for that, and save a lot of file size overhead to boot. Of course I would prefer it just play back waves as they are, but I'll play with what I got, as long as I know the rules.

Dantom discussed this recently in another thread on this forum. Apparently they're not happy with wavemix.dll's performance in this matter, nor are a lot of authors, so they're looking into what they can do about replacing the sound library with something better--hopefully something with MOD support.

I've noticed in Scream of the Stickster that the sound quality goes way down too; only one or two of the wavs have a slight hiss to them that's been impossible to remove (even with the best tools available), but they all play back with quite a bit of hiss. The loud versions of the monster roars should be hiss-free, since they're professionally recorded sound effects (bought and paid for) that have been edited down to extract a single roar from the main wav, and amplified. (Correction: I actually do notice a slight hiss on two of those, which I think comes from reducing them to 22KHz.) The quieter versions have had an echo applied, but shouldn't sound hissy either; I've gone through all of those and they're just fine.

MOD support would be fine, but I hope that won't mean no better support for wavs and/or none for mp3. I still think mp3 would be the best for sound effects, being the best file size to quality ratio.

I think more is going on than just reducing to 22khz. I got my file to sound pretty darned good in 22khz, but it still sounded crappy coming through BYOND. I think it's also reducing to 8 bits, and maybe even 11khz, as well as losing stereo image. I'll post an A/B comparison later if you're interested. Reducing sample rate will chop off high frequencies while reducing bit depth will introduce hiss and distortion. There seems to be a combination of that going on.

In my case it wasn't just a loss of quality -- that, I could live with. The sounds were actually playing back at a lower pitch!

A little birdie told me this may be in the next release. Hopefully. Barring unforseen complications.
