To record audio on your laptop, you can use sox (note that rec is a commnad installed with sox). Here are 2 useful sox commands

  • rec -r 44100 -c 2 -b 16 A4.wav
    • records at 44100 samples per sec, 2 channels, and 16 bits per sample
  • sox audio_2channels.wav audio_1channel.wav channels 1
    • converts from 2 channels to 1 channel
