15 docbook-to-man in your Build-Depends control field.

68 <title>DESCRIPTION</title>
70 <para>This manual page documents briefly the <command>&dhpackage;</command> command.</para>
72 <para>The library <emphasis remap='B'>aubio</emphasis> provides a small set of functions to extract events and
73 objects from audio, from live streams or still files. Onsets are used to label
74 the beginning of notes, pitches to label their height.</para>
76 <para><command>aubionotes</command> is still in an experimental state. Its aim is to segment notes
77 with onsets, and label them with their detected pitch. When started without an
78 input file argument (<option>-i</option>), aubionotes creates a jack input and a midi
79 output. When an input file is given, it outputs the results on the console.</para>
83 <title>OPTIONS</title>
85 <para>This program follows the usual GNU command line syntax, with long
86 options starting with two dashes (`-').
87 A summary of options is included below.</para>
90 <term><option>-i</option>
91 <option>--input filein</option></term>
93 <para>Run analysis on this audio file. Most common (uncompressed) formats are
98 <term><option>-o</option>
99 <option>--output fileout</option></term>
101 <para>Save results in this file. The file will be created on the model of the input
102 file. Results are marked by a very short wood-block sample.</para>
106 <term><option>-t</option>
107 <option>--threshold value</option></term>
109 <para>Set the threshold value for the onset peak picking. Typical values are within
110 <literal>0.001</literal> and <literal>0.900</literal>. Default is <literal>0.1</literal>. The <emphasis remap='B'>lower</emphasis> the <emphasis remap='B'>more
111 sensible</emphasis>. Try <literal>0.3</literal> in case of over-detections.</para>
115 <term><option>-j</option>
116 <option>--jack</option></term>
118 <para>Run in jack mode (default when started without input file) and creates a midi output.</para>
122 <term><option>-h</option>
123 <option>--help</option></term>
125 <para>Show summary of options.</para>
129 <term><option>-v</option>
130 <option>--verbose</option></term>
132 <para>Show results on the console.</para>
