I love this project idea! I don't want to oversell myself, I "do things" not nearly as much as I'd like or should (or used to).... more like "I study, research, fool around with equations, tend to know a lot about, &c". ;-)

But yeah, noise removal is in there! Other forms of restoration too.

_Ideally_ if you can somehow remember what the program you used was, it's possible for me to poke and see which approach they're using. But, assuming that knowledge is lost to the wind, can you link me to the recordings? Ideally a few "before and after". That way I can load them into MATLAB and start to see what's up.

Adobe's Audition is pretty good, iZotope RX is also well loved.

EDIT: Either way, and even if I don't end up doing anything with it, I'd love a link to the recordings. Dirty and clean.
