<p>
GstTRM computes <a class="ulink" href="http://www.musicbrainz.org/" target="_top">MusicBrainz</a>
TRM identifiers for audio streams using libmusicbrainz.
</p>
<p>
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.
</p>
<p>
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.
</p>
<p>
The TRM element will post a tag message with a <a
href="/usr/share/gtk-doc/html/gst-plugins-base-libs-0.10/gst-plugins-base-libs-gsttag.html#GST-TAG-MUSICBRAINZ-TRMID--CAPS"
><span class="type">GST_TAG_MUSICBRAINZ_TRMID</span></a>
tag on the bus once the TRM has been calculated (and also send a tag event
with that information downstream).
