Hello,

I have been using audacity to convert mp4 to mp3, it is slow and painful.
I have seen people talk about ffmpeg;
is there a way I can batch convert an entire folder of *.mp4 to *.mp3?

thank you for your time

Thanks for the responses.

As a summary the following worked for me:

–-------------how do I batch convert mp4 to mp3

have ffmpeg installed with codecs:

1)copy the files to a single directory.
2)make a quick script in kwrite by copying the following:

#!/bin/bash
*for i in .mp4
**do **
**ffmpeg -i “$i” -ab 128k “${i%mp4}mp3” **
done

  1. save as mp42mp3.sh in the same directory that the mp4 files reside.
  2. select file in dolphin > right click it > and select to make executable
  3. select from the dolphin menu to open a terminal window to open a terminal window in that directory.
  4. type:
    ./mp42mp3.sh

note: the 128k could be common bitrates, from 64k all the way up to 128k, 256k, 192k, 320k, etc…
