Convert CD-quality WAV to 8bit mono WAV using ffmpeg

Today I needed to record something in a WAV file that shouldn’t exceed 100 KB, when I used the standard “Sound Recorder” in Ubuntu, it recorded using the default CD-quality recording (resulting in a 280 KB file, so I used the “ffmpeg” tool to compress it to a 8bit mono file which resulted in a 28 KB file!

Here are the steps:

  1. Install “ffmpeg”, “sudo apt-get install ffmpeg”
  2. “ffmpeg -i Ahmad_Amr.wav -ar 8000 -ac 1 -acodec pcm_u8 output.wav’
