Make audio is a graphical tool to create audio CDs from MP3 or wav files. You can simply arrange a playlist of all songs that you want. The application converts MP3 files to WAV and then burns them on the CD.

Audio::CD is a Perl interface to libcdaudio (cd + cddb).

SYNOPSIS

use Audio::CD ();

Audio::CD provides a Perl interface to libcdaudio by Tony Arcieri, available from http://cdcd.undergrid.net/

Several classes provide glue for the libcdaudio functions and data structures.

Audio::CD Class ^

init

Initialize the Audio::CD object:
my $cd = Audio::CD->init;

stat

Stat the Audio::CD object, returns an Audio::CD::Info object.
my $info = $cd->stat;

cddb

Returns an Audio::CDDB object.
my $cddb = $cd->cddb;

play

Play the given cd track (defaults to 1).
$cd->play(1);

stop

Stop the cd.
$cd->stop;

pause

Pause the cd.
$cd->pause;

resume

Resume the cd.
$cd->resume;

eject

Eject the cd.
$cd->eject;

close

Close the cd tray.
$cd->close;

play_frames

$cd->play_frames($startframe, $endframe);

play_track_pos

$cd->play_track_pos($strarttrack, $endtrack, $startpos);

play_track

$cd->play_track($strarttrack, $endtrack);

track_advance

$cd->track_advance($endtrack, $minutes, $seconds);

advance

$cd->advance($minutes, $seconds);

get_volume

Returns an Audio::CD::Volume object.

my $vol = $cd->get_volume;

set_volume

$cd->set_volume($vol);

Audio::Mad is a Perl interface to the mad MPEG decoder library.

SYNOPSIS

use Audio::Mad qw(:all);

my $stream = new Audio::Mad::Stream();
my $frame = new Audio::Mad::Frame();
my $synth = new Audio::Mad::Synth();
my $timer = new Audio::Mad::Timer();
my $resample = new Audio::Mad::Resample(44100, 22050);
my $dither = new Audio::Mad::Dither();

my $buffer = join(, );
$stream->buffer($buffer);

FRAME: {
if ($frame->decode($stream) == -1) {
last FRAME unless ($stream->err_ok());

warn "decoding error: " . $stream->error();
next FRAME;
}

$synth->synth($frame);
my $pcm = $dither->dither($resample->resample($synth->samples()));

print $pcm;
next FRAME;
}

This module is an attempt to provide a perl interface to the MAD (MPEG Audio Decoder) library, written by Robert Leslie. It has been designed to be 100% object oriented, and to follow the MAD interface as closely as possible.

So far, most of the MAD library, plus two companion modules are provided as part of the interface. Seperate documentation is provided in perldoc for all of the modules in the Audio::Mad framework.

Audio::ESD is a Perl extension for talking to the Enlightened Sound Daemon.

SYNOPSIS

use Audio::ESD;
my $stream = Audio::ESD->play_stream({ # these are the defaults
sample_rate => 16000,
channels => 1,
fallback => 0,
bits_sample => 16,
encoding => linear })
or die "Failed to open ESD stream: $!n";
print $stream $data; # etcetera

This module provides a Perl wrapper around the Enlightened Sound Daemons client library. Input, output, and monitoring streams are supported, as well as some (but not all) of the control functions. Samples are supported but untested.

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.

Audio::File is a audio file abstraction library.

SYNOPSIS

use Audio::File;
my $file = Audio::File->new( "foo.bar" );

print "The ". $file->type() ."-file ". $file->name
." is ". int $file->length() ." seconds long.n";

print "Its interpreted by ". $file->tag->artist()
." and called ". $file->tag->title() ".n";

Audio::File abstracts a single audio file, independant of its format. Using this module you can access a files meta-info like title, album, etc. as well as the files audio-properties like its length and bitrate.

Currently only the formats flac, ogg vorbis and mp3 are supported, but support for other formats may be easily added.

Perl Audio Converter (PAC) is a tool for converting multiple audio types from one format to another. It supports MP2, MP3, Ogg Vorbis, FLAC, Shorten, Monkey Audio, FAAC (AAC/M4A/MP4), Musepack (MPC), Wavpack (WV), OptimFrog (OFR/OFS), TTA, LPAC, Kexis (KXS), AIFF, AC3, Lossless Audio (LA), AU, SND, RAW, VOC, SMP, RealAudio (RA/RAM), WAV, and WMA.
It can also convert audio from the following video formats/extensions: RM, RV, ASF, DivX, MPG, MKV, MPEG, AVI, MOV, OGM, QT, VCD, VOB, and WMV. A CD ripping function with CDDB support, batch and playlist conversion, tag preservation for most supported formats, independent tag reading/writing, and extensions for Konqueror and amaroK is also provided.
Enhancements:
- Added: MP4::Info dependency IO::String to pacpl-install
- Updated: License GPLv3
- Bug Fix: Directory conversions. pacpl was claiming the directory was empty and prompting to use the --recursive option...Thanks to John Meyer for the report.
