BRSTM files store sound data. They're used in Mario Kart Wii and possibly other games.
They contain an header, followed by a HEAD chunk, a ADPC chunk and a DATA chunk. All the data in those files are big-endian, except where mentioned. All the offsets are absolute (from begining of file), except where mentioned. All the sizes are in bytes, except where mentioned.
BRSTM header
The header is 64 bytes long.
| Offset | Size | Description |
|---|---|---|
| 0x0000 | 4 | "RSTM" (0x5253544D) |
| 0x0004 | 4 | Magic (0xFEFF0100) |
| 0x0008 | 4 | Size of the whole file |
| 0x000C | 4 | Unknown |
| 0x0010 | 4 | Offset to HEAD chunk |
| 0x0014 | 4 | Size of HEAD chunk |
| 0x0018 | 4 | Offset to ADPC chunk |
| 0x001C | 4 | Size of ADPC chunk |
| 0x0020 | 4 | Offset to DATA chunk |
| 0x0024 | 4 | Size of DATA chunk |
| 0x0028 | 24 | Unknown/Padding (zero) |
