...to convert the .wav to .mo3?
You can compress XM, S3M, IT and MOD files to MO3.
There is
no way to convert MP3, WAV, OGG or FLAC to MO3, because the way of saving the audio is fundamentally different. It's like giving your computer a cd and asking it to write out the notes for all instruments, the lyrics and special effects.
As a side note: you can use the whole wav file as a sample, use a tracker (for example Milkytracker) to create a mod that plays only that sample, and compress that result using MO3. That's completely
not what MO3 was ment for.
