The sheer size of these files (WAV tracks can be roughly 70MB per minute) is a testament to their quality; they are intended for professional use and critical listening. For comparison, official high-resolution releases of the album, such as the Blu-ray Pure Audio Disk, are preserved in the high-resolution 96kHz/24bit FLAC format, while standard CD-quality releases are often presented as 44.1kHz/16bit FLAC files. The WAV files of the multitracks, however, are the raw ingredients, the un-mixed elements that form the foundation of the final album we know.
