<!-- Process this file with docbook-to-man to generate an nroff manual
page: `docbook-to-man manpage.sgml > manpage.1'. You may view
the manual page with: `docbook-to-man manpage.sgml | nroff -man |
less'. A typical entry in a Makefile or Makefile.am is:
manpage.1: manpage.sgml

The docbook-to-man binary is found in the docbook-to-man package.
Please remember that if you create the nroff version in one of the
debian/rules file targets (such as build), you will need to include
docbook-to-man in your Build-Depends control field.

<title>DESCRIPTION</title>
<para><command>&dhpackage;</command> attempts to detect notes in audio
signals, segmenting consecutive events using onset detection, and
determining their pitch using a fundamental frequency extraction algorithm.
</para>
<para>When started without an input file argument
(<option>--input</option>), <command>&dhpackage;</command> creates a jack
input and a MIDI output. When an input file is given, the results are given
on the console.</para>

<title>OPTIONS</title>
<para>This program follows the usual GNU command line syntax, with long
options starting with two dashes (`-'). A summary of options is included
below.</para>

</listitem>
</varlistentry>
<varlistentry>
<term><option>-t</option>
<option>--threshold value</option></term>
<listitem>
