* siDecompressionParam Atom ('wave') *

The siDecompressionParam atom provides the ability to store data specific to a given audio decompressor in the * SoundDescription record. As example, some audio decompression algorithms, such as Microsoft’s ADPCM, require a * set of out-of-band values to configure the decompressor. These are stored in an atom of this type.

*

This atom contains other atoms with audio decompressor settings and is a required extension to the sound sample * description for MPEG-4 audio. A 'wave' chunk for 'mp4a' typically contains (in order) at least a 'frma' atom, an * 'mp4a' atom, an 'esds' atom, and a “Terminator Atom (0x00000000)” atom.

*

The contents of other siDecompressionParam atoms are dependent on the audio decompressor. *

    *
  • Size - An unsigned 32-bit integer holding the size of the decompression parameters atom
  • *
  • Type - An unsigned 32-bit field containing the four-character code 'wave'
  • *
  • TrackExtension atoms - Atoms containing the necessary out-of-band decompression parameters for the sound decompressor. * For MPEG-4 audio ('mp4a'), this includes elementary stream descriptor ('esds'), format ('frma'), and terminator atoms.
