Definition in the specification
Table 294 · Additional entries specific to a sound object
ISO 32000-1:2008, §13.3 · PDF page 515 ↗
/CO name
(Optional) The sound compression format used on the sample data. (This is separate from any stream compression specified by the sound object’s Filter entry; see Table 5 and 7.4, “Filters.”) If this entry is absent, sound compression shall not be used; the data contains sampled waveforms that shall be played at R samples per second per channel.
Qualifier: Optional
Conditional descriptions remain traceable. A definition alone does not implement a codec, a signature or every format mechanism. Read the coverage.
