CSW (Controller Speaker Wave) files contain sound data that is played through the Wii Remote Speaker. They are linked to BCT files. Super Mario Galaxy and Super Mario Galaxy 2 each contain only one CSW file, located in AudioRes/SpkRes/SpkRes.arc/bin/spkwave.csw.
File specifications
CSW files don't seem to contain a header. Instead they directly start with a table.
Sound offset table
| Offset | Type | Description |
|---|---|---|
| 0x0 | UInt32 (0x4) | Size of the file in bytes |
| 0x4 | UInt32 (0x4) | Amount of sounds |
| 0x8 + N * 4 | UInt32 (0x4) | Offset to sound data |
The rest of the section is padded to the nearest 0x20.
Sound data
| Offset | Type | Description |
|---|---|---|
| 0x0 | UInt32 (0x4) | Size of wave data in bytes |
| 0x4 | UInt32 (0x4) | Loop start in samples, 0xFFFF when no loop |
| 0x8 | UInt32 (0x4) | Loop end in samples, 0xFFFF when no loop |
| 0xC | Wave data |
The rest of the file is padded to the nearest 0x20.
Unused Speaker Sounds
Needs some research. Tho I can reliably say that the tennis racket sound is unused.
