PT Header (WIP)
SDT contains metadata headers, each 0x20 in length, for each sound in the archive. The metadata in question consists of a given sound's sample rate, compression, start offset, etc.
Offset | Length | Type | Description | Details |
---|---|---|---|---|
0x00 | 0x04 | UInt32 | Header ID (PT/0/0 /0x50540A00 ) |
|
0x18 | 0x04 | UInt32 | Audio start offset | Uses big-endian byte order. |
