So that's at least three cases

1. Unwanted ambient noises
2. Tape noise
3. Vynil noise

which require quite different techniques. Vynil noise for
example can (at least partially) be handled as a sequence
of discrete events that have a distinct signature (if the
digital transcription includes supersonic frequencies).



A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
