Free jack audio connection kit software for linux

JackLab Audio Distribution is a remastered openSUSE for musicians, producers and media creators.

The JackLab Team is proud to present the first public alpha-release of the JackLab Audio Distribution (JAD). The 1.2GB DVD iso can be downloaded from jacklab.org.

We have found that musicians have particular requirements for their Linux environment. A Linux-based distribution that is designed for music needs to be flexible, powerful, yet easy and quick to use. All of these things are essential in a busy, creative environment. Thinking about these requirements, we decided to base JAD on openSUSE due to its stability and long development history. All major administrative tasks can be done graphically and easily without having to learn any complicated terminal commands.

JAD will be fully compatible with the recently released openSUSE 10.2. It will contain a full production environment for media production, primarily music. For this, the JackLab team added a Realtime Kernel version 2.6.19 to have fast audio processing with a latency up to 1.5ms. The default audio system will be based on the the Jack Audio Connection Kit (JACK) which is designed for the needs of musicians and producers and gives a professional audio/midi controlling interface.

The installer is based on the acclaimed YaST2, which also serves as an easy-to-use administrative tool. To keep as many essential computer resources for music as possible, we have decided to use Enlightenment D17 desktop shell as the default window manager. KDE desktop environment is also included, so the user-friendly file manager - Konqueror, is available along with Kmail, Konversation, k3b and other KDE tools. For music creation and editing, we have included around 70 audio applications with sequencers, synthesizers and tools all installed and ready to go. User-friendly support for setting up and running VST instruments and effects is given. Additionally, there are applications for video production and a graphic suite that are included on the DVD. For browsing the internet, we have included Firefox 2.0 chosen for its stability, security and extendability.

JAD is a community based effort and is the culmination of the work of many contributors. Recently, JackLab and PackMan (packman.links2linux.de) have joined forces to offer JAD access to the PackMan repositories so that up-to-date audio software, non-audio software and multimedia codecs are available to JAD users. The JAD development team would like you to participate in the development process too. There are different ways you can help:

-As a tester, you can download the most recent version and use the bugtracker to report any problems.
-You can participate in the graphics contest: The best graphics submitted will be used as default for the bootscreen, wallpaper, skins and icons.
-You can submit feature requests and take part in discussions on the mailing list.
-For taking part in providing user support, there is a web based forum and an IRC channel - it is also an essential part of the development process to see feedback.

DESCRIPTION ^
The Jabber::Connection package provides basic functions for connecting clients and components to a Jabber server.

Audio::Ecasound is a Perl binding to the ecasound sampler, recorder, fx-processor.

SYNOPSIS
One function interface:
use Audio::Ecasound qw(:simple);

eci("cs-add play_chainsetup");
eci("c-add 1st_chain");
eci("-i:some_file.wav");
eci("-o:/dev/dsp");
# multiple n separated commands
eci("cop-add -efl:100
# with comments
cop-select 1
copp-select 1
cs-connect");
eci("start");
my $cutoff_inc = 500.0;
while (1) {
sleep(1);
last if eci("engine-status") ne "running";

my $curpos = eci("get-position");
last if $curpos > 15;

my $next_cutoff = $cutoff_inc + eci("copp-get");
# Optional float argument
eci("copp-set", $next_cutoff);
}
eci("stop");
eci("cs-disconnect");
print "Chain operator status: ", eci("cop-status");

Object Interface

use Audio::Ecasound;

my $e = new Audio::Ecasound;
$e->on_error();
$e->eci("cs-add play_chainsetup");
# etc.
Vanilla Ecasound Control Interface (See Ecasounds Programmer Guide):
use Audio::Ecasound qw(:std);

command("copp-get");
$precise_float = last_float() / 2;
command_float_arg("copp-set", $precise_float);
warn last_error() if error();
IAM Interface, pretend interactive mode commands are functions.
use Audio::Ecasound qw(:iam :simple);

# iam commands as functions with s/-/_/g
my $val = copp_get;
copp_set $val+0.1; # floats are stringified so beware
eci("-i /dev/dsp"); # not all commands are exported

Audio::Ecasound provides perl bindings to the ecasound control interface of the ecasound program. You can use perl to automate or interact with ecasound so you dont have to turn you back on the adoring masses packed into Wembly Stadium.
Ecasound is a software package designed for multitrack audio processing. It can be used for audio playback, recording, format conversions, effects processing, mixing, as a LADSPA plugin host and JACK node. Version >= 2.2.X must be installed to use this package. "SEE ALSO" for more info.

Net::FreeDB2::Connection is a FreeDB/CDDB abstract connection class.

Net::FreeDB2::Connection is an abstract class to represent connections to FreeDB/CDDB servers. After a successfull connection, FreeDB/CDDB queries, reads etc can be made to obtain/provide information from/to FreeDB/CDDB databases.

CONSTRUCTOR

new (OPT_HASH_REF)

Creates a new Net::FreeDB2::Connection object. By default connect () is called to initiate the connection but see option no_connect. See the implementation for complements/restrictions.

Options for OPT_HASH_REF may include:

client_name

Mandatory option to name the connecting client software.

client_version

Mandatory option with the client software version string.

client_host

The hostname of the client. Defaults to &Sys::Hostname::hostname ().

client_user

The user of the client. Defaults to scalar (getpwuid ($>));

freedb_host

The FreeDB/CDDB host. Defaults to freedb.freedb.org.

freedb_port

The port on the FreeDB/CDDB host.

proxy_host

Proxy host.

proxy_port

Port on the proxy host. Defaults to 8080.

proxy_user

Proxy user name to use.

proxy_passwd

Proxy password to use.

no_connect

Do not call connect () during instanciation.

Jack Meter is a basic console based DPM (Digital Peak Meter) for JACK. I wrote it for quickly checking remote signal levels, without having to run X11 to use a pretty graphical meter such as meterbridge.
Usage
Usage jack_meter [-f freqency] [-r ref-level] [-w width] [-n] [< port >, ...]
where -f is how often to update the meter per second (8)
-r is the reference signal level for 0dB on the meter
-w is how wide to make the meter (79)
-n changes mode to output meter level as number in decibels
< port > the ports to monitor (multiple ports are mixed)
Enhancements:
- uses new JACK API (and hence requires JACK version 0.100.0)
- connects multiple ports on the command line
- informational messages are new sent to STDERR
- added -n option to output level as number in decibels

JackMiniMix is a simple mixer for the Jack Audio Connection Kit with an OSC based control interface.

It supports a user configurable number of stereo inputs, which can then be queried and controlled by sending it OSC messages. JackMiniMix is free software released under the GPL licence.

OSC Interface

Channels numbers range from 1 to the total number of channels. Gains are in floating point decibels in the range -90 to 90 dB, where -90 dB is treated as infinite.

/mixer/get_channel_count - Get the number of channels
replies with:
/mixer/channel_count (i)

/mixer/channel/set_gain (if) - Set the gain of channel i to f dB
replies with:
/mixer/channel/gain (if)

/mixer/channel/set_label (is) - Set the label of channel i to s
replies with:
/mixer/channel/label (is)

/mixer/channel/get_gain (i) - Get gain of channel i
replies with:
/mixer/channel/gain (if)

/mixer/channel/get_label (i) - Get the label of channel i
replies with:
/mixer/channel/label (is)

/ping - Check mixer is still there
replies with:
/pong

Replies are send back to the port/socket that they were sent from.

Clearsilver is a fast, powerful, and language-neutral HTML template system. In both static content sites and dynamic HTML applications, ClearSilver CGI Kit provides a separation between presentation code and application logic which makes working with your project easier.
The design of Clearsilver began in 1999, and evolved during its use at onelist.com, egroups.com, and Yahoo! Groups. Today many other projects and websites using it.
High Performance and Language Neutral. Because Clearsilver is written as a C-library, and exported to scripting languages like Python, Perl, Java and Ruby via modules, it is extremely fast. This also means you can work with the same template system independent of the language your project is in.
Pluggable Look and Feel. Clearsilver makes it easy to face lift a site by providing a new set of templates. It is possible to easily run more than one look and feel at once, and share components with a base look and feel to reduce maintenance.
Internationalization Support. Clearsilver makes it trivial to support internationlization. You write your templates in your native language and included tools automatically extract and catalog language strings for translation.
Advanced features. Built in support for advanced features such as gzip compression, smart whitespace stripping, parametric macros, online debugging mode, url and javascript string escaping, and more.
Enhancements:
- Compilation problems were fixed.
- Improvements were made to the Java and Perl wrappers and several functions were added for template expressions.
