is the standard audio format used by iTunes Store. All songs that are available for download in the iTunes Store use this format. So if you want to convert your m4a files to mp3 files, you can use Avconv
which is a very fast video and audio converter that comes with the Libav
To be able to use this converter, you need to install the Avconv package:
sudo apt-get install avconv
Now, you need to navigate to the directory that contains the m4a files that you want to convert:
/home/YOURNAME/YOURFOLDER is the full path to the folder where you have stored the m4a files.
To convert all the m4a files in this folder, paste Ctrl+Shift+V this command into the terminal window:
for k in *.m4a; do avconv -i "$k" -b:a 320k -c:a libmp3lame "$(basename "$k" .m4a)".mp3; rm "$k"; done
This command loops through the chosen directory, converts all m4a files to mp3 files and then deletes the m4a files. If you want to keep the original files (m4a), remove this part:
TIP: You can use the
mc command to browse directories directly from the terminal window. To install it, run the following command:
To launch this tool, type
mc in a terminal window and use the arrow keys to navigate between directories.
