So, you want to extract some audio from a video ey? Sure! No problem! You can do just that using ffmpeg, here’s the command string.
In this example, i’ll extract the whole audio track to a mp3 file, with a 320k bit (constant) rate and 44100hz audio rate (high quality mp3):
ffmpeg -i “whatever.format” -vn -ac 2 -ar 44100 -ab 320k -f mp3 output.mp3
Here’s a short explanation on what every parameter does:
- -i “input file”
- -vn “skip the video part”
- -ac “audio channels”
- -ar “audio rate”
- -ab “audio bit-rate“
- -f “file format to use”
- (the end if the string) “output file”
