I think the widespread homecomputer emulator file formats should be supported, else nobody will use MAME for them at all. But plain audio (WAV) version must be still there. This may be done through a plugin (possibly realtime-converting data like a unix-stream or such) to make the emulation internally see audio signals.

E.g. Atari XL datassette has a stereo tape head and could play speech/music from cassette during load of a program. E.g. cassette games by Europa played a long music track from cassette while loading. Some programs also started and stopped the tape to output speech (quiz questions and such) although this of course only worked in fixed order (you could not wind the tape through software). It would make sense to support such audio tracks through an additional MP3 file since WAV eats much disk space.
