Debian Multimedia Jack packages

Main goal of this project is to ease usage of legacy, not JACK-ified apps, in a JACK MIDI enabled system. a2jmidid is a daemon that implements automatic bridging. For every ALSA sequencer port you get one JACK MIDI port. If ALSA sequencer port is both one input and one output, you get two JACK MIDI ports, one input and one output.

Aj-snapshot is a small program that can be used to make snapshots of the connections made between JACK and/or ALSA clients. Because JACK can provide both audio and MIDI support to programs, aj-snapshot can store both types of connections for JACK. ALSA, on the other hand, only provides routing facilities for MIDI clients. Aj-snapshot is meant to be used from the command line.

G. JACK Transport is a standalone application that provides access to the Jack Audio Connection Kit's, JACK transport mechanism via a dynamic graphical slider.

In other words: this software allows one to seek Audio/Video media files when they are played along jack transport. Intended for audio-engineers or A/V editors that work with Ardour, Ecasound, Hydrogen, Xjadeo, etc.

Additionally it provides G. JACK Clock, a "Big Clock" display for jack-transport.

Jaaa (JACK and ALSA Audio Analyser) is an audio signal generator and spectrum analyser designed to make accurate measurements.

Jaaa allows you select on of the four inputs, 'Min' and 'Max' the min and max displayed frequencies. There can be up to two markers which helps accurately read off values in the display.

A simple and robust command-line tool to send MIDI beat clock that accurately follows JACK Transport.

It also features an instumentation tool to parse and dump incoming MCLK messages.

jack-stdout is a small tool that writes JACK audio-sample data to buffered standard output. jack-stdin reads raw audio data from standard input and writes it to a JACK audio port.

By default jack-stdout writes 16 bit signed integer raw audio data (much like mpg123 -s) at JACK's samplerate, but it can output signed/unsigned 8/16/24/32 bit integer and 32bit floating-point data, both big/little endian.

jack-tools is a collection of small tools for the JACK Audio Connection Kit.

JACK allows the connection of multiple applications to an audio device, as well as allowing them to share audio between themselves.

jack-dl loads dsp algorithms from shared libraries. Commands are sent as OSC packets over a UDP connection.

jack-record is a light-weight JACK capture client to write an arbitrary number of channels to disk.

jack-scope draws either a time domain signal trace or a self correlation trace. Multiple input channels are superimposed, each channel is drawn in a different color. jack-scope accepts OSC packets for interactive control of drawing parameters.

jack-osc publishes the transport state of the local JACK server as OSC packets over a UDP connection. jack-osc allows any OSC enabled application to act as a JACK transport client, receiving sample accurate pulse stream timing data, and monitoring and initiating transport state change.

jack-plumbing maintains a set of port connection rules and manages these as clients register ports with JACK. Port names are implicitly bounded regular expressions and support sub-expression patterns.

jack-udp is a UDP audio transport mechanism for JACK. jack-udp is obsolete: use net driver instead.

jack-play is a light-weight JACK sound file player. It creates as many output ports as there are channels in the input file.

jack-transport is a JACK session manager. It reads configuration information from a system wide and a user specific configuration file and manages sessions involving the JACK daemon proper and optionally a set of secondary jack daemons.

• support for hardware and software time stamping via the Linux SO_TIMESTAMPING socket option.
• support for the Linux PTP Hardware Clock (PHC) subsystem by using the clock_gettime family of calls, including the new clock_adjtimex system call
• implementation of Boundary Clock (BC) and Ordinary Clock (OC)
• transport over UDP/IPv4, UDP/IPv6, and raw Ethernet (Layer 2)
• support for IEEE 802.1AS-2011 in the role of end station

PTP provides higher precision and faster synchronization than NTP even without hardware support. With hardware support, sub-microsecond accuracy can be expected. Whereas NTP is intended for WAN use, PTP is designed for LAN environments and makes use of UDP multicast.

Mudita24 is a modification of the Linux alsa-tools' envy24control: an application controlling the digital mixer, channel gains and other hardware settings for sound cards based on the VIA Ice1712 chipset aka Envy24. Unlike most ALSA mixer controls, this application displays a level meter for each input and output channel and maintains peak level indicators. This is based on Envy24's hardware peak metering feature.

Mudita24 provides alternate name to avoid confusion with "envy24control 0.6.0" until changes in this version propagate upstream. As balance to the "Envy", this project needed some Mudita "In Buddhism the third of the four divine abidings is mudita, taking joy in the good fortune of another. This virtue is considered the antidote to envy and the opposite of schadenfreude."

This utility is preferable to alsamixer for those with ice1712-based cards: M-Audio Delta 1010, Delta 1010LT, Delta DiO 2496, Delta 66, Delta 44, Delta 410 and Audiophile 2496.

This package contains a script to prioritize IRQ thread handlers on a kernel patched with realtime-preempt patch from Ingo Molnar. The script takes advantage of the fact that realtime kernels use threads for IRQs management, and as such these threads (like any other thread running on your system) can be given maximum priority in an effort to minimize the latency of audio peripherals.

The script identifies the audio devices present on the machine and raises the priority of the threads that handle the IRQs of such devices.

This package provides two applications, zita-a2j and zita-j2a. They allow one to use an ALSA device as a Jack client, to provide additional capture (a2j) or playback (j2a) channels.

Functionally these are equivalent to the alsa_in and alsa_out clients that come with Jack, but they provide much better audio quality. The resampling ratio will typically be stable within 1 PPM and change only very smoothly. Delay will be stable as well even under worse case conditions, e.g. the Jack client running near the end of the cycle.

Two simple demo programs are provided. alsa_delay a ALSA version of jack_delay. And alsa_loopback

zita-bls1 - The Blumlein Shuffler convert binaural stereo signals into a form suitable for reproduction using a convential stereo speaker pair.

Command line jack application providing 2, 3, or 4-band, 4th order crossover filters. The filter type is continuously variable between Linkwitz-Riley (-6dB at the xover frequency) and Butterworth(-3 dB at the xover frequency). Outputs are exactly phase matched in the crossover regions.

The application supports up to 16 channels.

Configuration is by a text file using 'OSC' style syntax (similar to Ambdec and Jconvolver). Apart from the basic filter parameters, the following can be set:

• Channel labels (used for naming Jack ports).
• Frequency band names (used in output port names).
• Optional output autoconnections.
• For each channel: gain and delay (in ms).
• For each frequency band: gain and delay.

• IP6 fully supported.
• Requires zita-resampler, no other dependencies.

PNMixer is a simple mixer application designed to run in your system tray. It integrates nicely into desktop environments that don't have a panel that supports applets and therefore can't run a mixer applet. In particular it's been used quite a lot with fbpanel and tint2, but should run fine in any system tray.

PNMixer is designed to work on systems that use ALSA for sound management. Any other sound driver like OSS or FFADO, or sound server like PulseAudio or Jack, are currently not supported (patches welcome).

This package allows you to use M-Audio's USB MIDI and Audio interfaces with Linux. These devices require a firmware download before an operating system driver (e.g. ALSA's snd-usb-audio) can access them.

Supported devices:

• MidiSport 1x1
• MidiSport 2x2
• MidiSport 4x4
• MidiSport 8x8
• KeyStation (old models: 49, 61)
• Oxygen
• Radium49
• Radium61
• Uno The loader is not required for the MidiSport 2x4 and for newer KeyStation models (49e, 61es, Pro 88).

This driver allows AudioScience cards to be controlled using the HPI API.

Carla is an audio plugin host, with support for many audio drivers and plugin formats. It has some nice features like automation of parameters via MIDI CC (and send output back as MIDI too) and full OSC control.

Carla currently supports LADSPA (including LRDF), DSSI, LV2, VST2/3 and AU plugin formats, plus GIG, SF2 and SFZ file support. It uses JACK as the default and preferred audio driver but also supports native drivers like ALSA, DirectSound or CoreAudio.

The waveform is displayed in realtime, so you can always see the signal the instant it comes through JACK's input port.
