+/**
+ * List of PCE (Program Configuration Element) for the channel layouts listed
+ * in channel_layout.h
+ *
+ * For those wishing in the future to add other layouts:
+ *
+ * - num_ele: number of elements in each group of front, side, back, lfe channels
+ * (an element is of type SCE (single channel), CPE (channel pair) for
+ * the first 3 groups; and is LFE for LFE group).
+ *
+ * - pairing: 0 for an SCE element or 1 for a CPE; does not apply to LFE group
+ *
+ * - index: there are three independent indices for SCE, CPE and LFE;
+ * they are incremented irrespective of the group to which the element belongs;
+ * they are not reset when going from one group to another
+ *
+ * Example: for 7.0 channel layout,
+ * .pairing = { { 1, 0 }, { 1 }, { 1 }, }, (3 CPE and 1 SCE in front group)
+ * .index = { { 0, 0 }, { 1 }, { 2 }, },
+ * (index is 0 for the single SCE but goes from 0 to 2 for the CPEs)
+ *
+ * The index order impacts the channel ordering. But is otherwise arbitrary
+ * (the sequence could have been 2, 0, 1 instead of 0, 1, 2).
+ *
+ * Spec allows for discontinuous indices, e.g. if one has a total of two SCE,
+ * SCE.0 SCE.15 is OK per spec; BUT it won't be decoded by our AAC decoder
+ * which at this time requires that indices fully cover some range starting
+ * from 0 (SCE.1 SCE.0 is OK but not SCE.0 SCE.15).
+ *
+ * - config_map: total number of elements and their types. Beware, the way the
+ * types are ordered impacts the final channel ordering.
+ *
+ * - reorder_map: reorders the channels.
