<a name="BtSongInfo.description"></a><h2>Description</h2>
<p>This class exposes the meta-data of a song as <a href="/usr/share/gtk-doc/html/gobjectgobject-The-Base-Object-Type.html#GObject-struct"><span class="type">GObject</span></a> properties. These are
for one pure data fields such as author and song name. These fields get used
when recording a song to a file (rendering) in the form of meta-tags.</p>
<p>Further there are fields that determine rythm and song-speed. The speed is
determined by <a class="link" href="BtSongInfo.html#BtSongInfo--bpm" title="The “bpm” property"><span class="type">“bpm”</span></a>. The rythm is determined by <a class="link" href="BtSongInfo.html#BtSongInfo--bars" title="The “bars” property"><span class="type">“bars”</span></a>
and <a class="link" href="BtSongInfo.html#BtSongInfo--tpb" title="The “tpb” property"><span class="type">“tpb”</span></a>. If 'bars' is 16, than on can have 1/16 notes.
And if 'ticks per beat' is 4 one will have 4 beats - a classic 4/4 meassure.
For a 3/4 meassure, 'bars' would be 12. Thus bars = beats * tpb.</p>
<p>Finally, the class offers a couple of timing related conversion functions.</p>
