9.21 Sound Recording Command Line

When recording from the command line the command is:

  $ sound-recorder -c 2 -b 16 -P -S 5:00 recording.wav

The options set stereo recording (-c 2), 16 bit sampling (-b 16), priority threading (-P) to ensure high priority in CPU usage, and limiting the recording to 5 minutes. The output is written to the file recording.wav.

Many of these options are the default so you can simply:

  $ sound-recorder -P recording.wav

Use Ctrl-C to stop the recording.
