Detailed Description

Westwood Studios AUD file demuxer by Mike Melanson (melan.nosp@m.son@.nosp@m.pcisy.nosp@m.s.ne.nosp@m.t) 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.
