Also GSM 6.10 WAV (mobile) which produces a mono WAV file encoded with the compressed, lossy GSM 6.10 codec as used in mobile telephones.
Other uncompressed files: includes all the uncompressed audio formats that Audacity can export, including 4-bit (A)DPCM, 8-bit U-Law/A-Law, 24-bit, 32-bit and 64-bit options. GSM 6.10 WAV (mobile) will also exhibit considerable loss of quality as it was a format designed for mobile telephony. Those 4-bit formats and the lossless 8-bit U-Law/A-Law formats save file size by reducing their bit depth, in a similar way that any of the uncompressed formats can be made proportionately smaller by reducing their sample rate (and thus reducing the high frequencies they can contain). There is no loss of quality compared to the original audio when playing uncompressed formats, except for some possible loss of low frequencies in the 4-bit (A)DPCM formats. 
The most common uncompressed formats are WAV and AIFF. The following are all uncompressed audio formats in which every sample of sound is represented by a binary number.
