command-line utility to record from microphone

Question

I am looking for command-line utility that monitors the microphone, and if you start to speak, writes the file. Recording period should be adjusted.

Solution is:

   sox -t alsa default recording.wav silence 1 0.1 5% 1 1.0 5%

Solution

From http://dabase.com/u/record_wav/

arecord -vv -fdat stackoverflow.wav

Does your Mic work with Skype testing? Is it enabled via alsamixer?

[Admin]

I tried it and it is working > arecord -vv -fdat stackoverflow.wav I think the problem is that you are not selecting microphone in the settings, you have analog input instead change that and it should work

@hendry: Did you even read the question. The asker wants something that only triggers when a sound is heard, and then records for a specific period of time.

@BjarkeFreund-Hansen lol I only noticed that this fact when I have find this solution great to me. The author failed to address what he wanted clearly in the title, and even Google "didn't even read the question" and led me here!
