.SH NAME
PDL::Demos::Sound \- play PDL\-generated sounds
.SH DESCRIPTION
.IX Header "DESCRIPTION"
This module is intended to be auto-discovered by the mechanisms of
PDL::Demos.  That module also defines our interface.
.PP
The demo creates some simple sound waves (a scale and a chord) and
pipes them to an external sound player program.  It knows how to
invoke \f(CW\*(C`aplay\*(C'\fR (from alsa-utils), \f(CW\*(C`play\*(C'\fR and \f(CW\*(C`sox\*(C'\fR (the latter two
from SoX \- Sound eXchange).  All of these are available as packages in
Linux distributions, SoX is also available from
<https://sourceforge.net/projects/sox/> for Microsoft Windows and
MacOS.
.PP
If no suitable player is discovered, the demo does not die but shows
an explanation where to obtain them.
