NAME

PDL::Demos::Sound - play PDL-generated sounds

DESCRIPTION

This module is intended to be auto-discovered by the mechanisms of PDL::Demos. That module also defines our interface.

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 aplay (from alsa-utils), play and sox (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.

If no suitable player is discovered, the demo does not die but shows an explanation where to obtain them.

To install PDL, copy and paste the appropriate command in to your terminal.

cpanm

cpanm PDL

CPAN shell

perl -MCPAN -e shell
