60 <refpurpose>a command line tool for real time extraction of musical notes.</refpurpose>
65 <command>&dhpackage; <parameter>[options] [-i soundfile]</parameter></command>
69 <title>DESCRIPTION</title>
71 <para><command>&dhpackage;</command> attempts to detect notes in audio
72 signals, segmenting consecutive events using onset detection, and
73 determining their pitch using a fundamental frequency extraction algorithm.
76 <para>When started without an input file argument
77 (<option>--input</option>), <command>&dhpackage;</command> creates a jack
78 input and a MIDI output. When an input file is given, the results are given
79 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 (`-'). A summary of options is included
91 <term><option>-i</option>
92 <option>--input filein</option></term>
95 <para>Run analysis on this audio file. Most common uncompressed formats are
101 <term><option>-o</option>
102 <option>--output fileout</option></term>
105 <para>Save results in this file. The file will be created on the model of the
106 input file. Results are marked by a short wood-block sample.</para>
111 <term><option>-P</option>
112 <option>--pitch mode</option></term>
115 <para>The pitch detection function to run. Available functions are
116 <emphasis>yinfft</emphasis>, <emphasis>yin</emphasis>,
117 <emphasis>mcomb</emphasis>, <emphasis>fcomb</emphasis>, and
118 <emphasis>schmitt</emphasis>.</para>
123 <term><option>-O</option>
124 <option>--onset mode</option></term>
127 <para>The onset detection function to run. Available functions are
128 <emphasis>complexdomain</emphasis>, <emphasis>hfc</emphasis>,
129 <emphasis>phase</emphasis>, <emphasis>specdiff</emphasis>,
130 <emphasis>energy</emphasis>, <emphasis>kl</emphasis> and
131 <emphasis>mkl</emphasis>. By default, both Kullback Liebler (kl) and complex
132 domain are used in parallel.</para>
137 <term><option>-t</option>
138 <option>--threshold value</option></term>
141 <para>Set the threshold value for the onset peak picking. Typical values are
142 within <literal>0.001</literal> and <literal>0.900</literal>. Default is
143 <literal>0.1</literal>. <emphasis>Lower</emphasis> threshold values imply
144 <emphasis>more</emphasis> onsets detected. Try <literal>0.3</literal> in
145 case of over-detections.</para>
150 <term><option>-j</option>
151 <option>--jack</option></term>
153 <para>Run in jack mode (default when started without input file) and creates a midi output.</para>
157 <term><option>-v</option>
158 <option>--verbose</option></term>
160 <para>Show results on the console (default).</para>
164 <term><option>-h</option>
165 <option>--help</option></term>
167 <para>Show summary of options.</para>
176 <para>For now the program has only been tested on audio signals sampled at
177 44.1 kHz.</para>
