Detailed Description

Westwood Studios VQA & AUD file demuxers by Mike Melanson (melanson@pcisys.net) for more information on the Westwood file formats, visit: http://www.pcisys.net/~melanson/codecs/ http://www.geocities.com/SiliconValley/8682/aud3.txt.

Implementation note: There is no definite file signature for AUD files. The demuxer uses a probabilistic strategy for content detection. This entails performing sanity checks on certain header values in order to qualify a file. Refer to wsaud_probe() for the precise parameters.
