Creating new synth sounds does not excite me much...
Some things I'd like AI audio researchers to work on:
- High quality isolation of vocals and other instruments in recordings
- Convert audio recordings into multitrack midi/vst recordings - so a recording of a jazz quartet could be converted into the notes and appropriate patches/sample banks
- Convert between styles of music
- Convincing "vocal synthesis" - think text to speech but with singing allowing emulation of famous singers
