Although I personally prefer FLAC than Monkey’s Audio (APE), some audio files are in latter’s format. It’s easier than you may expected to play APE files in Linux.
Player Using GStreamer as Backend
Audio players including the super famous Amarok and Banshee are using GStreamer for decoding. Now let me take Fedora as an example. Just install the RPM package gstreamer-ffmpeg and voila!
su -c 'yum install gstreamer-ffmpeg'
Player Based on MPlayer
SMPlayer, UMPlayer are in this list. Nothing special you need to do. It’s already there. Play your favourite track now!
