So you downloaded an album in the cue/FLAC format (a cue sheet + a flac file) and I want to convert it to multiple mp3 files? Here’s what you need to do:
Install the necessary software: audio-convert, gstreamer-flac, mp3splt. Assuming you’re using Ubuntu and have enabled the universe repository, open a terminal and type
sudo apt-get install audio-convert gstreamer-flac mp3splt
Now cd into the directory where the flac file is and type
(replace CDImage for whatever you flac file is called).
After selecting “mp3″ for the file format and the quality preset you want, audio-convert goes to work for a while: first decompressing the CDImage.flac into a wav and then compressing the latter into an mp3.
Now to “cut” the single mp3 into multiple files – one for each track:
mp3splt -f -c CDImage.cue CDImage.mp3
And that’s it. Additionally you can also install the audio-convert-nautilus-script or SoundConverter if you don’t want to use the command line for converting from flac to mp3.
