Convert an MP3 from 48000 to 44100 Hz?

Question

I have some MP3s that are in 48000 Hz sampling frequency. I'd like to burn them to CD, so I have to reduce the sampling frequency into 441000.

How to do that using ffmpeg?

Answer 1

ffmpeg doesn't look to be the appropriate tool; I'd normally use sox for audio-only files.

$ sox file1.mpg -r 44100 file1-enc.mpg

If you want to try using ffmpeg anyway, I think the correct command would be something like

$ ffmpeg file1.mpg -ar 44100 file1-enc.mpg
