+ * The <i>Event timing codes</i> allows synchronisation with key events in the
+ * audio.
+ *
+ * The events are an array of timestamp and type pairs. The time stamp is set to
+ * zero if directly at the beginning of the sound or after the previous event.
+ * All events are sorted in chronological order.
+ *
+ * The events $E0-EF are for user events. You might want to synchronise your
+ * music to something, like setting off an explosion on-stage, activating a
+ * screensaver etc.
+ *
+ * There may only be one ETCO frame in each tag.
