60 <refpurpose>a command line tool to extract onsets and tempo from sound files.</refpurpose>
65 <command>&dhpackage; <parameter>[options] -i soundfile</parameter></command>
69 <title>DESCRIPTION</title>
71 <para><command>&dhpackage;</command> attempts to detect onset times, the
72 beginning of discreted sound events, or beat locations, in audio
75 <para>When using the <option>--cut</option> option,
76 <command>&dhpackage;</command> takes an input sound file and produce small
77 files sliced at onset locations (or silences). The slices can then be sent
78 for example to a player, a sequencer, or a sampler.</para>
80 <para>A plotting module is available via the Gnuplot Python package.</para>
