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

Thanks to http://superuser.com/questions/94794/convert-a-mp3-to-wav-file-with-mplayer for the quick how-to

It added background noise to output with reduce quality
How to fix it ?

Unfortunately, the quality is very low, that’s why it became so small in size.
