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%

Please see the [FAQs](http://stackoverflow.com/faq). That is not the type of questions we deal with here. — wallyk, Feb 01 '12 at 06:51

Does your Mic work with Skype testing? Is it enabled via `alsamixer`? – hendry Feb 01 '12 at 07:24
Yes Mic working with skype, enabled – Feb 01 '12 at 11:12
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 – Robin Apr 07 '15 at 20:01

@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. – Bjarke Freund-Hansen Mar 29 '17 at 08:02
@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! – user26742873 May 05 '21 at 08:39
