Offset	Type	Value	Description
0x00	uint32_t	0x809	Magic number.
0x04	uintptr_t	Pointer to location in system memory. Usually `nullptr`.
0x08	uint32_t		Container size.
0x0C	uint32_t		Container header size.
0x10	uint32_t		If value at `0x04` is non-zero then this will be, too.
0x14	uint32_t		Audio data size. ‎

RwaWave

Each wave is of type RwaWave and is stored in a RwLLNode in an RwLinkList.

class RwaWave 
{
    RwaUniqueID uniqueID;
    RwaWaveDef* waveDef; // Pointer to location in system memory.
    RwaWaveFormat format;
    RwaWaveFormat targetFormat; // Usually identical to format. 
    uint32_t uncompressedLength;
    void* data;
    void* state;
    RwUInt32 flags;
    RwaObj* obj;
};

RwaUniqueID

    }

    struct name 
    {

        char* copyName;
    }
};

RwaWaveFormat
