"When choosing how to encode my CD’s, I decided not to use the most common format, MP3. The problem with MP3 is that it is a “lossy” format which loses sound fidelity, and in addition it can’t be freely implemented in Free Software because it is restricted by software patents. I chose to use the FLAC (Free Lossless Audio Codec) format instead. I chose FLAC because it’s a software patent-free, lossless way of encoding music. Using FLAC guarantees that my music will be playable on any device (and most devices support FLAC)."
