Explanation:

There are two types of audio formats currently supported under Sony's CommunityPlace VRML 2.0 browser: *.WAV files and *.MOD files.

WAV files need to be within the following guidelines:

- 8-bit, unsigned or 16-bit unsigned
- at or less than 22k sample rate

That's pretty much it. Really.

MOD files need to be within the following guidelines:

- 8-bit, signed instraments
- *.aif instrament format
- ProTracker MOD format
- looping instraments under 128k each

I haven't seen a MOD editor for the PC yet. All our MOD files were created on the Mac platform, thus the *.aif instrament format. Pretty straight forward too.
