What is the difference between a .wav and an .mp3 file?

416 bit WAV files are uncompressed and have a full frequency response where as an MP3 320 file is lossy and compressed. Lossy compression is a class of data encoding methods that uses inexact approximations (or partial data discarding) to represent the content. These techniques are used to reduce data size for storage, handling, and transmitting content.

WAV files are of course better quality and I recommend those when possible… but sometimes this can be inconvenient, and take a lot longer to download. If you purchase a WAV file here, please be patient with the extra time it takes to download, depending on the speed of your internet.

Gaearth Dreaming, for example, has a DVD also of the CD music, for the best quality sound, next to Super Audio (see Color of Sound CD). DVDs can hold more information than a CD, so they can be encoded with the quality used during the recording process (96,000 samples per second, versus The Super Audio disc can be played on a regular DVD player, but if that player plays SA CDs, also known as DSD, it will read that layer, as it is a dual-layer disc.
