Sound sample description version 0 ('stsd')

Overview

There are currently three versions of the sound sample description, versions 0, 1 and 2. Version 0 supports only uncompressed audio in raw ('raw ') or twos-complement ('twos') format, although these are sometimes incorrectly specified as either 'NONE' or 0x00000000.

Version 0 of the sound description format assumes uncompressed audio in 'raw ' or 'twos' format, 1 or 2 channels, 8 or 16 bits per sample, and a compression ID of 0.
