Hi all,

I'm pretty new to the world of audio on linux, so please excuse the 
"newbeeness" of my question. :-)

I'm a in the process of making a police/EMS/fire radio recorder. At 
first, I tought of doing a program similar to ScanRec(1) from the 
windows world -- that is not record when the sound is below a certain 
threshold. This could easily be done with ecasound's -ge parameter.

However, I started thinking and found that it would be better to have a 
different file for each segment. For example, if there is
- 45 seconds of speech, followed by
- 3 minutes of silence,  followed by
- 2 minutes of speech
I would get two files, one 45 seconds long and one 2 minutes long.

Does such a program allready exists, and if not, what would be the 
best/easiest way of doing it?
