[music-dsp] What's still to be done in this field?

[Oded]

Also:
Changing timbre in a profound but very natural sounding way e.g.:
Play a sax and change it to trumpet,
Speak/sing your own voice and change it to somebody else's voice,
Change a sound into something that sounds like an acoustic musical
instrument but one that doen't exist and has a different sound than any
other known intrument.

Add detail to sound so that a recording with a bad mic will sound like it
was done with a good mic.

Oded.
