We only sell 16-bit FLAC files.
FLAC files are the same quality as WAV files however they are compressed, so are a smaller file size. FLAC stands for Free Lossless Audio Codec and is an open source format. For more information about this visit: Sourceforge.
Please note iTunes DOES NOT support the playback of FLAC files. There are extensions to iTunes that allow the playback of FLAC files. and lots of other media players available that support this file format. For example VLC.
