I've been using this for years to downconvert high-resolution mp3 files to 32 KB mono mp3 files. It will convert an entire CD of high-res mp3 files and put them where you tell it to. (Pressing the ` key while in the directory that contains the mp3 files you want to downconvert will open a console in that directory. Just copy this code into that console, replace the /mnt// at the end with the path to the directory where you want it to put the files and hit Enter.)
for f in *.mp3;do ffmpeg -i "$f" -y -f mp3 -acodec libmp3lame -ab 32k -ac 1 -ar 22050 /mnt//"$f";done
I didn't make it up. Someone in the forum gave it to me, I can't remember who. You can probably change the numbers to get the mp3 quality you want. Enter ffmpeg --help in a console for more info on the available options.
