Record Audio via Terminal in Ubuntu/Debian

1. Make sure you’ve enabled recording from Capture in Volume Control/GNOME ALSA Mixer.
2. Install lame , a MP3 encoder by entering sudo apt-get install lame in Terminal.
3. When you are ready to record, paste arecord -f cd -t raw | lame -x – test.mp3 in Terminal and press Enter. It should save a file called test.mp3 in your current directory in Terminal.
4. If you want to stop recording, kill the arecord process by typing killall arecord in Terminal and press Enter.
5. If you did all this correctly and enabled Capture for recording, you should get a lovely MP3 file.
6. If necessary, edit the MP3 file in Audacity to set the volume to the right level and cut out unnecessary data. Install audacity by entering sudo apt-get install audacity in Terminal.

Hopefully it worked for you! If it didn’t, leave a comment and I shall try to assist you.
