Free cheap car audio software for linux

CrystalAudio is a FVWM-Crystal configuration tuned for use on an audio workstation. It has many new applications for the menu, including many sound-related applications and improved sound controls. The project launches qjackctl at startup.
The final goal of the project is to make the FVWM-Crystal menu compatible with the freedesktop specification and to provide some tools to generate the menu entries and icons from desktop and icon files provided by the applications in the system.
Enhancements:
- generate-fvwm-crystal-menu work with both new and old type application desktop files, so it is time for the 2.0 version.
- A lot of debugging have been done on that script: See the ChangeLog for the details.
- Added support for stalonetray in all the recipes.

Cactus is just an audio file player. But it has some features that makes it different from other players.
There are music databases and there are players like xmms with a small and leightweight, skinable GUI.
Cactus combines these two types in one player! With Cactus you can read your music collection into a database, create a playlist by browsing/searching it and finally switch to player view(F2-Key).
Main features:
- Plattform independent
- Browse your music collection by artist, albums and titles
- Tiny lightweight player combined with a powerful database for organizing mp3-files
- Save and Load m3u Playlists
- Supports ID3v1(read/write) and ID3v2(read)
- Easy tagging of mp3-files
Enhancements:
- Some bugs concerning the playlist/tag-editing now fixed...

Data::ICal::Entry::Alarm::Audio represents an audio alarm in an iCalendar file.

SYNOPSIS

my $valarm = Data::ICal::Entry::Alarm::Audio->new();
$valarm->add_properties(
attach => [ "ftp://host.com/pub/sounds/bell-01.aud", { fmttype => "audio/basic" } ],
# Dat*e*::ICal is not a typo here
trigger => [ Date::ICal->new( epoch => ... )->ical, { value => DATE-TIME } ],
);

$vevent->add_entry($valarm);

A Data::ICal::Entry::Alarm::Audio object represents an audio alarm attached to a todo item or event in an iCalendar file. (Note that the iCalendar RFC refers to entries as "components".) It is a subclass of Data::ICal::Entry and accepts all of its methods.

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

SYNOPSIS

use Audio::CD ();
my $cd = Audio::CD->init;

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);

CarWorld is a small driving simulator/demo I use to test various things of interest. It was mostly developed when I was a student. Car World is released with the full source code under the GNU General Public License.

The rendering

The two top pictures represent an slightly older version (v0.072) but graphically similar of CarWorld as it was presented for my project. v0.072 includes an OpenGL based renderer allowing
file input and displaying of texture mapped models with interpolated surface normals, real time projected shadows (as seen in the dino lights example).
background object
on screen command line to modify visual and simulation parameters

The mechanics

based on classical mechanics
uses standard metrics (Newtons, meters, seconds...)
there are no constraints on the environment surface
variable length time increments and variable increment number means "CarWorld time" is not dependent on frame rate.
adjustable simulation specs include: metrics, mass, moment of inertia around rotation axis, suspension pre load, compression damping, rebound damping, engine torque output, air friction, surface friction.

JACK is a low-latency audio server, written for POSIX conformant operating systems such as GNU/Linux and Apples OS X.

Jack audio connection kit can connect a number of different applications to an audio device, as well as allowing them to share audio between themselves. Its clients can run in their own processes (ie. as normal applications), or can they can run within the JACK server (ie. as a "plugin").

JACK was designed from the ground up for professional audio work, and its design focuses on two key areas: synchronous execution of all clients, and low latency operation.
