These are actually for video camera but will record sound as well.

I Think Montion will not start if a webcam is not plugged and I don't want to use a webcam...

A very good program is Audacity, which is available for Windows and Linux.
Download same from: http://audacity.sourceforge.net/download/

Hi,

I know audacious but it's not what I search, and...audacious work with X and not in command line mode.
I'm searching a command line program to capture sound if a sound level is reached, like what motion do when images captured by the webcam moove...

I do not have the hardware to try it but I was just wondering if this works.

cat /dev/dsp > sound.wav

If it does then:

dd if=/dev/dsp of=sound.wav bs=1M count=32

might solve your query

No, the record must start if an a sound level is reached...

You can even make clever things like taking samples every 1 millisecond, averaging the levels and then comparing to a threshold. All you need is simple bash arithmetic (or bc) and then you can test the sound level in a loop. When the level is reached, the recording starts. Your application shows how easy one can use bash for complicated applications.
