page: `docbook-to-man manpage.sgml > manpage.1'. You may view
the manual page with: `docbook-to-man manpage.sgml | nroff -man |

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 extract fundamental
frequency in sound files. When no pitch candidate is found, the output is
0. Five fundamental frequency extraction methods are available. Results can
be printed in Hertz or in MIDI pitch.</para>
<para>A plotting module is available via the Gnuplot Python package.</para>
