37  * Channel Layout Tag
38  * This tells which channels are present in the audio stream and the order in
39  * which they appear.
40  *
41  * @note We're using the channel layout tag to indicate channel order
42  * when the value is greater than 0x10000. The Apple documentation has
43  * some contradictions as to how this is actually supposed to be handled.
44  *
45  * Core Audio File Format Spec:
46  * "The high 16 bits indicates a specific ordering of the channels."
47  * Core Audio Data Types Reference:
48  * "These identifiers specify the channels included in a layout but
49  * do not specify a particular ordering of those channels."
