==Comparison of coding schemes==
{{Main article|Audio compression (data)|Comparison of audio coding formats}}

Audio in WAV files can be encoded in a variety of audio coding formats, such as [[GSM]] or [[MP3]], to reduce the file size. All WAV files, even those that use [[MP3]] compression, use the <code>.wav</code> extension.

This is a reference to compare the [[monophonic]] (not [[stereophonic]]) audio quality and compression bitrates of audio coding formats available for WAV files including LPCM, [[ADPCM]], Microsoft [[GSM 06.10]], [[CELP]], [[Smart Bitrate Control|SBC]], [[Truespeech]] and [[MPEG]] Layer-3. These are the default ACM codecs that come with Windows.
