AUD (assumingly stands for "audio") is an audio compression format used by Westwood Studios in the late 1990's. It takes raw 16-bit pulse-code modulation audio data compressed with the lossless IMA-ADPCM algorithm. The lossless compression makes it similar to the newer format, FLAC. An AUD decoder used to be part of Winamp's built in waveform plugin, but it was removed. However, there are custom plug-ins that can play AUD in their native form as well as programs to convert AUD into uncompressed WAV.

How to Obtain

AUD files usually need to be extracted from game resource files, a process that is different for nearly every game that uses the format.
