Record Sound or Voice in Ubuntu

To record sound using linux/ubuntu we don't need and special softwares, a simple command line tool is available called arecord. One of the simple way to use the command in the terminal as follows.

$ arecord filename.wav

The recording is continued as long as Cntrl+C is not pressed, recording infinitely. The recording will get saved in the file named filename.wav

If the recording needs to be stopped after a specific interval we can use the option -d

$ arecord -d 10 filename.wav
