Measure Impulse Responses using a sine sweep and deconvolution. For more complete introduction to this method, see http://kokkinizita.linuxaudio.org/linuxaudio/downloads/aliki-manual.pdf

A set of ambisonics plugins, mainly to be used within Ardour. Mono and stereo to B-format panning, horizontal rotator, square, hexagon and cube decoders.

AmbDec is an Ambisonics decoder for up to 36 speakers. It can be used for both horizontal and full 3-D systems of first, second and third order. The decoding matrices are fully user-configurable. AmbDec has some advanced features not found on most decoders:

• Dual frequency band operation.
• Speaker distance compensation.
• Near-field effect compensation.

All three features can be selectively enabled or disabled in the configuration.

Ardour is a multichannel hard disk recorder (HDR) and digital audio workstation (DAW). It can be used to control, record, edit and run complex audio setups.

Ardour supports pro-audio interfaces through the ALSA project, which provides high quality, well designed device drivers and API's for audio I/O under Linux. Any interface supported by ALSA can be used with Ardour. This includes the all-digital 26 channel RME Hammerfall, the Midiman Delta 1010 and many others.

Ardour has support for 24 bit samples using floating point internally, non-linear editing with unlimited undo, a user-configurable mixer, MTC master/slave capabilities, MIDI hardware control surface compatibility.

It supports MIDI Machine Control, and so can be controlled from any MMC controller and many modern digital mixers.

Ardour contains a powerful multitrack audio editor/arranger that is completely non-destructive and capable of all standard non-linear editing operations (insert, replace, delete, move, trim, select, cut/copy/paste). The editor has unlimited undo/redo capabilities and can save independent "versions" of a track or an entire piece

Ardour's editor supports the community-developed LADSPA plugin standard. Arbitrary chains of plugins can be attached to any portion of a track. Every mixer strip can have any number of inputs and outputs, not just mono, stereo or 5.1. An N-way panner is included, with support for various panning models. Pre- and post-fader sends exist, each with their own gain and pan controls. Every mixer strip acts as its own bus, and thus the bus count in Ardour is unlimited. You can submix any number of strips into another strip.

Ardour's channel capacity is limited only by the number on your audio interface and the ability of your disk subsystem to stream the data back and forth.

JACK (the JACK Audio Connection Kit) is used for all audio I/O, permitting data to be exchanged in perfect samplesync with other applications and/or hardware audio interfaces.

Ardour is sample rate and size neutral - any hardware formats from 8 to 32 bits, and rates from 8kHz to 192kHz. Internal processing in 32/64 bit IEEE floating point format.

DRC is program used to generate correction filters for acoustic compensation of HiFi and audio systems in general, including listening room compensation. Program generates just the FIR correction filters, which can be used with a real time or offline convolver to provide real time or offline correction.

DRC doesn't provide convolution features, and provides only some simplified, although really accurate, measuring tools.

JACK is a low-latency sound server, allowing multiple applications to connect to one audio device, and to share audio between themselves.

This dummy package depends on the current default JACK implementation.

Japa, is a 'perceptual' or 'psychoacoustic' audio spectrum analyser. Possible uses include spectrum monitoring while mixing or mastering, evaluation of ambient noise, and (using pink noise) equalisation of PA systems.

It supports up to four audio inputs of which two can graphically be compared. Additionally a pink noise and white noise generator is running after starting japa.

Jconvolver is a Convolution Engine for JACK using FFT-based partitioned convolution with multiple partition sizes. It can execute up to a 64 by 64 convolution matrix (i.e. 4096 simultaneous convolutions) as long as your CPU(s) can handle the load.

Package include example files for easy start using jconvolver. These files will be installed in /usr/share/convolver/config-files dir. More info in /usr/share/doc/jconvolver/README.CONFIG.

You can also download additional reverb file jconvolver-reverbs.tar.bz2 from http://kokkinizita.linuxaudio.org/linuxaudio/downloads/index.html

Qjackctl offers a user interface for controlling the JACK sound server daemon. At the same time it figures as a JACK patch bay and monitoring tool.

REV1 is a reworked version of the reverb originally developed for Aeolus. Its character is more 'hall' than 'plate', but it can be used on a wide variety of instruments or voices. It is not a spatialiser - the early reflections are different for the L and R inputs, but do not correspond to any real room. They have been tuned to match left and right sources to some extent.

In Stereo mode a dry/wet mix control is provided, so it can be used either as an insert or in send/return mode. For mono just connect one of the two channels.

In Ambisonic mode (selected by the -B command line option) the only option is the send/return mode.
