Sony Wave64 (.w64) is a general audio container format.
Wave64 is an extension to WAV to support a basically limitless amount of samples, channels, bit depths, etc.
Like all other RIFF based formats, if a chunk's payload size is not even, it is padded by 1 byte to make it so.
it's chunk format is very similar to Wave's, except it's chunks are all lower case, and have been extended to 128 bits, with 96 bits of identifiable junk in order to be a GUID.
The ChunkSize field includes the size of the marker and it's own size as well.
| Type | Size |
