WAV is an uncompressed, lossless format that stores raw audio at full quality. Files are large, but the audio is pristine, which is why it is the standard for editing and mastering. FLAC is a lossless format that compresses audio with no loss of quality — typically to about half the size of WAV. It is the favourite of audiophiles for archiving music. Both WAV and FLAC are lossless, so your audio quality is preserved exactly.
