Enumeration Type Documentation

mov 'chan' tag reading/writing.

Author
Justin Ruggles Channel Layout Tag This tells which channels are present in the audio stream and the order in which they appear.
Note
We're using the channel layout tag to indicate channel order when the value is greater than 0x10000. The Apple documentation has some contradictions as to how this is actually supposed to be handled.

Core Audio File Format Spec: "The high 16 bits indicates a specific ordering of the channels." Core Audio Data Types Reference: "These identifiers specify the channels included in a layout but do not specify a particular ordering of those channels."
