+ * <para>
+ * GstTRM computes <ulink url="http://www.musicbrainz.org/">MusicBrainz</ulink>
+ * TRM identifiers for audio streams using libmusicbrainz.
+ * </para>
+ * <para>
+ * A TRM identifier is something like an 'acoustic fingerprint', the aim is
+ * to uniquely identify the same song regardless of which source it comes from
+ * or which audio format the stream is in.
+ * </para>
+ * <para>
+ * The TRM element will collect about 30 seconds of audio and let
+ * libmusicbrainz calculate a preliminary audio signature from that. That audio
+ * signature will then be sent over the internet to a musicbrainz.org server
+ * which will calculate the TRM for that signature.
+ * </para>
+ * <para>
+ * The TRM element will post a tag message with a #GST_TAG_MUSICBRAINZ_TRMID
+ * tag on the bus once the TRM has been calculated (and also send a tag event
+ * with that information downstream).
+ * </para>
+ * <title>Example pipeline</title>
+ * <para>
+ * Here is a test pipeline to test the TRM element:
+ * <programlisting>
+ * gst-launch -m filesrc location=somefile.ogg ! decodebin ! audioconvert ! trm ! fakesink
+ * </programlisting>
+ * this should (among many other things) print the tag message with the TRM ID.
+ * </para>
