What Is a WAV File?

The uncompressed standard

WAV, short for Waveform Audio File Format, is a container that stores audio without compression. Every sample is preserved exactly, which is why WAV is considered lossless and why it is the go-to format for professional audio work. The tradeoff is size: a WAV is many times larger than an MP3 of the same song.

Because nothing is discarded, a WAV is the ideal source for mastering and the format distributors and pressing plants expect. It is also the safest format for archiving your finished work.
