[TriLUG] automated Audio processing in Linux

There is a sound utility for backing up and restoring old vinyl recordings 
called gramofile. It's quite possible that he is using that. Along with 
Audacity you have a powerful suite for ripping records to mp3/ogg. I don't 
believe either of these programs has the ability to do what you want, Jeremy. 
If I understand correctly you are looking for something that will record 
audio unattended, or record audio when it encounters something other than 
white noise. You need something to "trip' the record function when it hears 
non-white noise and shut off when it encounters only white-noise. You could 
always do what Marty suggested and just record a continuous stream and strip 
out the white noise. I think that would be far easier. You could also have a 
look at the Linux Audio pages: 
http://linux-sound.org/

Might be something there.
