Audio::OSS 0.0501

Audio::OSS is a pure-perl interface to OSS (open sound system) audio devices.

SYNOPSIS

use Audio::OSS qw(:funcs :formats :mixer);

my $dsp = IO::Handle->new(" dsp_reset($dsp) or die "reset failed: $!";

my $mask = get_supported_formats($dsp);
if ($mask & AFMT_S16_LE) {
set_fmt($dsp, AFMT_S16_LE) or die set format failed: $!";
}
my $current_format = set_fmt($dsp, AFMT_QUERY);

my $sps_actual = set_sps($dsp, 16000);

set_fragment($dsp, $fragshift, $nfrags);
my ($frags_avail, $frags_total, $fragsize, $bytes_avail)
= get_outbuf_info($dsp);
my ($bytes, $blocks, $dma_ptr) = get_outbuf_ptr($dsp);

my $mixer = IO::Handle->new(" my $miclevel = mixer_read($mixer, SOUND_MIXER_MIC);

Audio::OSS is a pure Perl interface to the Open Sound System, as used on Linux, FreeBSD, and other Unix systems.

It provides a procedural interface based around filehandles opened on the audio device (usually /dev/dsp* for PCM audio).

It also defines constants for various ioctl calls and other things based on the OSS system header files, so you dont have to rely on .ph files that may or may be correct or even present on your system.

Currently, only the PCM audio input and output functions are supported. Mixer support is likely in the future, sequencer support less likely.
