 /**
+ * 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."
