Audio::DSP 0.02

Audio::DSP is a Perl interface to *NIX digital audio device. SYNOPSIS use Audio::DSP; ($buf, $chan, $fmt, $rate) = (4096, 1, 8, 8192); $dsp = new Audio::DSP(buffer => $buf, channels => $chan, format => $fmt, rate => $rate); $seconds = 5; $length = ($chan * $fmt * $rate * $seconds) / 8; $dsp->init() || die $dsp->errstr(); # Record 5 seconds of sound for (my $i = 0; $i < $length; $i += $buf) { $dsp->read() || die $dsp->errstr(); } # Play it back for (;;) { $dsp->write() || last; } $dsp->close(); Audio::DSP is built around the OSS (Open Sound System) API and allows perl to interface with a digital audio device. It provides, among other things, an initialization method which opens and handles ioctl messaging on the audio device file. Audio::DSP also provides some rudimentary methods for the storage and manipulation of audio data in memory. In order to use Audio::DSP, youll need to have the necessary OSS drivers/libraries installed. OSS is available for many popular Unices, and a GPLed version (with which this extension was initially developed and tested) is distributed with with the Linux kernel..
