NAME

Audio::LADSPA::Plugin::Play - Audio::LADSPA glue to Audio::Play

SYNOPSIS

use Audio::LADSPA::Network;
use Audio::LADSPA::Plugin::Play;

my $net = Audio::LADSPA::Network->new();
my $sine = $net->add_plugin( label => 'sine_fcac' );
my $play = $net->add_plugin('Audio::LADSPA::Plugin::Play');

$net->connect($sine,'Output',$play,'Input');

$sine->set('Frequency (Hz)' => 440); # set freq
$sine->set(Amplitude => 1);   # set amp

for ( 0 .. 100 ) {
    $net->run(100);
}

DESCRIPTION

This module is a glue module, acting as a 1-input Audio::LADSPA::Plugin that sends its input to Audio::Play. This is currently the easiest way of getting sound from the Audio::LADSPA modules.

CAVEATS

Due to the limitation of Audio::Play, this module is currently mono only, but it should be reasonably portable.

All data coming in on its input port is immediately send out to the sound card when the run() method is called, which probably means that on slower machines you need run() calls of more samples. On my machine runs of 100 samples work fine most of the time, but YMMV.

This module is based on Audio::LADSPA::Plugin::Perl, which is unfinished, so calling certain methods from the Audio::LADSPA::Plugin API on it might not work. See Audio::LADSPA::Plugin::Perl for details.
