Description
A game's background-music file: a ZWAV header (magic, a version, a size field and zero padding) followed by one long stream of 16-bit little-endian stereo samples, usually recorded at 44100 Hz. Filestar adds a WAV header and converts it like any audio; the sample rate is a guess, because the header does not state one.
