Software Map

Bristol Audio Synthesiser is an emulator for diverse keyboard instruments. Currently about 20 are implemented: various Moog, Sequencial Circuits, Oberheim, Yamaha, Roland, Hammond, Korg, ARP, and Vox algorithms. The application consists of an audio engine and an associated graphical user interface called Brighton which acts as a dedicated master keyboard for each emulation.

Horgand is a graphical FM real time organ with
auto-accompaniment. It is JACK capable, with DSP
effects to emulate and store organ sounds. It is
available either standalone or as a DSSI plugin.

klick is an advanced JACK-based metronome,
supporting tempo changes, meter changes, and more.
It allows you to define complex tempo maps for
entire songs or performances.

GNU GTick is a metronome application. It features a
scale from 10 beats per minute to 1000 BPM and
arbitrary beat modes (meters). It uses GTK+2 and
OSS.

CLAM is a multiplatform software framework for research and application development for the Audio and Music domains. It offers a conceptual model for building systems as well as tools for the analysis, synthesis, and transformation of audio signals using high level representation (notes, spectral peaks, etc.). It also provides multiplatform system abstraction and tools for audio and MIDI file handling, device handling, GUI and XML support, and more. It has proper Linux audio architecture integration (Ladspa, Alsa, OSC, Jack, VST, etc.) and rapid graphical prototyping both for the processing core and the user interface (Qt designer integration).

Csound is a powerful and yet easy to use musical
synthesis package. Csound was constructed in the
tradition of so-called music-N languages, among
which the best-known is Music V. It consists of an
orchestra- and score-driven executable, written in
C for portability. Since Csound is a computational
language, it is highly flexible and efficient;
complexity is gained only at the expense of
computation power. Basically, Csound reads some
files and creates the result as a sound file on
disk or, on faster machines, in real time through
a DAC.

Spiral Synth is a physically modelled polyphonic analogue synthesizer. It is capable of creating the kind of sounds made by hardware analogue synths, the noises used in electronic music. You can also use it to make stranger sounds too. MIDI is supported, and it uses the standard OSS/Free sound output (/dev/dsp).

Cheese Tracker is a program to create module music. It aims to have an interface and feature set similar to that of Impulse Tracker. It works on Unix systems and on Windows (using cygwin), but all the interface/audio code is fully modular and abstracted in individual classes, which should make the porting of this program to other platforms very easy.

aubio is a library for audio labelling. Features
include onset detection, silence detection, beat
tracking, and pitch detection. The goal of this
project is to provide automatic labelling features
to other audio software projects. Functions can be
used offline in sound editors and software
samplers, or online in audio effects and virtual
instruments.

Hydrogen is a simple real-time Drum machine/sequencer. It features a graphical user interface based on Qt, a sample-based audio engine, Jack/ALSA/OSS/PortAudio and Export to disk audio drivers, ALSA MIDI input, ability to import/export XML-based song and drumkit files, 192 ticks per pattern, 16 voices with volume, mute, solo, ADSR, and pan capabilities, and import of samples in wave, au, and aiff format.

jMax is a visual programming environment for building interactive real-time musical and multimedia applications by allowing the user to interactively design dataflow circuits. The basic data types that can go through are integers, symbols, lists, etc. It is an event-driven system and has been used for MIDI processing. A second part of the system (DSP) allows a continuous signal to flow through a circuit, which is most useful for PCM sound (ie. microphone, sound files, etc.). The system is extensible by using shared libraries, you may add data processor types, data types, GUI elements, device types, and more. Data processors may also be designed as circuits and reused.

amber aims to be an easy-to-use granular synthesis
tool for Linux to assist composers and electronic
musicians in creating interesting and complex
sounds. More information on the theory and
application of granular synthesis techniques can
be found at http://shoko.calarts.edu/~eric/gs.html.
