<title>DESCRIPTION</title>
<para><command>&dhpackage;</command> attempts to detect onset times, the
beginning of discreted sound events, or beat locations, in audio
signals.</para>
<para>When using the <option>--cut</option> option,
<command>&dhpackage;</command> takes an input sound file and produce small
files sliced at onset locations (or silences). The slices can then be sent
for example to a player, a sequencer, or a sampler.</para>
<para>A plotting module is available via the Gnuplot Python package.</para>
