Fixed mix-up of N' and N in description of file
AST files contain PCM16 (16-bit signed) sound data. They're used in Super Mario Galaxy for musics, Legend of Zelda: Twilight Princess, and possibly in other games.
They contain a header, followed by BLCK chunks which are divided in blocks (channels).<br>
All the data in those files are big-endian, except where mentioned.<br>
All the offsets are absolute (from begining beginning of the file), except where mentioned.<br>
All the sizes are in bytes, except where mentioned.<br>

Stereo is the most common type. Some musics music in SMG, such as the beach theme, are 4.0 Surround, though.

Where:<br>
- N ' is the number of channels (entry 0x000C in AST header)<br>- N' is the block size (entry 0x0004 in BLCK chunk header)<br>
