m4a convert

webvolutionary · 11-19-2006, 10:03 PM

I have a collection of aac files in a folder and would like to convert them all to mp3 format. My collection is in folders as such: /music/artist/album/01 title.m4a (01 being the track number). I would like to convert all the files and rename them to include the artist and album info but I am at a loss as to how to do this.

Googling turned up the following to convert the files:

Code:

$ ffmpeg -i input.m4a -acodec mp3 -ac 2 -ab 128 output.mp3

But I would have to go into each directory and run this and it still dosen't solve my renaming problems. Anyone have any ideas?

First BACKUP.

Code:

cd /music
find . -type f -name \*.m4a |while read infile; do
  ffmpeg -i "$in" -acodec mp3 -ac 2 -ab 128 "${in%.m4u}.mp3"
done

Check that mp3 files were generated correctly before deleting:

Code:

find . -type f -iname \*.m4a |while read infile; do
  rm -f "$in"
done
