Reading time: < 1 minute Another title for this post could be: "Getting audio from video clips". Because you could do it with MP4 (Mpeg4), WebM, Mov, FLV, etc. We are going to use ffmpeg to that:
ffmpeg -i input_file.webm -ab 128k -ar 44100 out_file.mp3
The meaning of the parameters:
- ab: the audio bitrate in bps
- ar: the audio sample rate in hz
And if you have a directory with a lot of files to convert you could use:
find . -name "*.webm" -print0 |while read -d $'\0' file; do ffmpeg -i "$file" -ab 128k -ar 44100 -y "${file%.webm}.mp3";done
Pay attention to “find” and “while read” commands combinations because we want to support files with spaces.
I hope this is as useful for you as for me.
