AST files contain PCM16 (16-bit signed) sound data. They're used in Super Mario Galaxy for musics, 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 of file), except where mentioned.<br>
All the sizes are in bytes, except where mentioned.<br>
Stereo is the most common type. Some
musics in SMG, such as the beach theme, are 4.0 Surround, though.
=== AST file structure ===
- N is the number of channels (entry 0x000C in AST header)<br>- N
' is the block size (entry 0x0004 in BLCK chunk header)<br>
