I have a number of sound effects from my sound designer, and I'm currently trying to export them as 8-bit WAVs for my game. The advice from Artifacts when exporting sound as 8-bit WAV worked perfectly for the first few, but, for one of them, the "Behemoth walk sound," it's not working.
Fairly bad artifacts appear when I try to do this for the Behemoth walk sound. I've tried deleting all the higher frequencies, but they come back as soon as I hit "save." I've read that applying dither when quantizing helps, but it seemed to have no effect. I've tried these tactics both in Audacity and Audition.
I'm pretty stuck, and this is blocking the next release of the game, so any ideas help.
Here's one of the 16-bit versions of this sound:
And here's a characteristic attempt of turning it into 8-bit: https://www.dropbox.com/s/sb4flrlyl1l8c8a/Behemoth%20walking%20v2%20volume%20adjusted%20audition.wav?dl=0
