Level-sensitive (vox) recording?

Hi everyone - I'm new on the list.

Does anyone know of an app that will start recording when audio appears at the sound-card input? (ie. is "level-sensitive") - or, perhaps, start another app/script?

I have RecAll for win95/NT - but would like to switch to Linux for reasons of realiability (!)

I work for an international Short-wave radio station, and am publishing our programmes on the web, as well as wanting to archive programmes in high-quality (probably mpeg3) - preferably in an automated fashion.

At the moment I schedule scripts to run the RA Encoder at appropriate times, but, for several reasons, it would be of great assistance if I was able to use some sort of "vox" control...

Thanks in advance.

well- I think that I have heard of something like this for linux. But I am not sure
where to get it. You might try http://sound.lovebead.com, they have alot of sound
programs. You will need to get the commercial soundcard drivers, because the one
included with the kernel only supports output, I believe.Or maybe its that it doesnt support full duplex. Good luck
