How to compress all mp3 files in a directory using ffmpeg?

Question

linux

To compress one file I use this command:

ffmpeg -i ~/Music/file.mp3 -q:a 9 ~/Music_compress/file.mp3

How can I do this for all files in the '~/music' directory?

Answer 1

cd ~/Music ;
mkdir -p Music_compress ;
find  -maxdepth 1 -iname "*.mp3" -type f -exec ffmpeg -i {} -q:a 9 Music_compress/{} \;

Answer 2

for f in *.mp3; do ffmpeg -i "$f" -q:a 9 "Music_compress/${f%.*}.mp3"; done
