+
+This is especially useful when the @gstbuffer is in non-interleaved (planar)
+layout, in which case this function will use the information in the
+@gstbuffer's attached #GstAudioMeta in order to map each channel in a
+separate "plane" in #GstAudioBuffer. If a #GstAudioMeta is not attached
+on the @gstbuffer, then it must be in interleaved layout.
+
+If a #GstAudioMeta is attached, then the #GstAudioInfo on the meta is checked
+against @info. Normally, they should be equal, but in case they are not,
+a g_critical will be printed and the #GstAudioInfo from the meta will be
+used.
+
+In non-interleaved buffers, it is possible to have each channel on a separate
+#GstMemory. In this case, each memory will be mapped separately to avoid
+copying their contents in a larger memory area. Do note though that it is
+not supported to have a single channel spanning over two or more different
+#GstMemory objects. Although the map operation will likely succeed in this
+case, it will be highly sub-optimal and it is recommended to merge all the
+memories in the buffer before calling this function.
