Wave Dictionary

The RenderWare Audio Wave Dictionary container format is used to store a collection of audio files, or "waves." It uses the file extension .awd. Each wave is of type RwaWave and is stored in a RwLLNode in an RwLinkList.

Layout

Offset	Type	Value	Description
0x00	uint32_t	0x809	Magic number.
0x04	uint32_t		Usually 0.
0x08	uintptr_t		Pointer to audio data.
0x0C	RwaWaveDict*		Pointer to wave dictionary.
0x10	uint32_t		If value at 0x04 is non-zero then this will be, too.
0x14	uint32_t		Audio data size. ‎
