RCVerb ("ReaClassical Verb")

A reverb suitable for classical music based on zita-rev1. Available as LV2 and CLAP by default (with optional VST3, VST2 and LADSPA). This plugin is part of the ReaClassical project along with RCComp ("ReaClassical Compressor") and Enover (RCVerb's big sister) additionals plugins, also written in Faust.

Wam-Studio

Wam-Studio’s is an online tool for creating audio projects that you can imagine as multi-track music. Each track corresponds to a different "layer" of audio content that can be recorded, edited, or just integrated (using audio files for example). Some track can be used to control virtual instruments: in that case we record the sound that is generated internally by these virtual instruments (and played using a MIDI piano keyboard, for example).

Tracks can be added or removed, played isolated or with other tracks. They can also be "armed" for recording, and when the recording starts, all other tracks will play along, while the armed track will record new content.

Wam-Studio can host WAM plugins and in particular Faust ones, which can be built following this tutorial.

SNES Echo Simulator

SNES Echo is an cross-platform audio processing plugin, written in Faust. It simulates the SNES SPC700 DSP reverb/echo effect. This plugin does not strive for bit-accuracy and overflow handling, but instead being audibly indistinguishable for "normal" SPCs.

Sentinelle

Sentinelle is a sound and robotic art installation made by Jérôme Abel. A robot-probe is placed in a dark place, a cellar. It scans its surroundings with two lasers. The reliefs of the old walls, their imperfections, mold, appear thanks to the perfectly straight lines of the lasers. Its movements are synchronized with a sound program. From these very simple visual and sound choreographies are born an imaginary on its functioning and the origin of its presence. The spectator observes in a mirror a robot which observes and testifies. Does it communicate with other systems? Does it send information? Its energy is precious, like a heartbeat or a breath, it works in a segmented way with periods of silence. Likewise, his movements are slow and relentless.

Ambisonics in KMH studios and Lilla salen

The general idea behind using ambisonics for diffusing sounds in a space is to, in the first stage, encode an audio signal to a representation of a sound field - a B-format signal. This B-format signal is independent of whatever speaker array the signal will later be diffused on. In the second stage the B-format signal is decoded to the layout of a particular speaker array. In between these two stages a number of transformations may be applied, but the sound source specification may conveniently be specified in the encoder. The decoders are written in Faust.

Patches for the OWL Pedal/Eurorack Module

This is a collection of patches written or ported specifically for the OWL. Most of them were written using FAUST and if you want to modify them you'll need to have a working FAUST installation. C++ source code (the .hpp files) for the OWL can be generated by running the "updateFaustPatches.py" python script. Then you will need to rebuild the OWL firmware and upload it to the device.

Kiwi

Kiwi is a graphical programming environment dedicated to music and sound creation, such as Max or Pure Data softwares, but offering a real-time collaborative approach: Kiwi allows several distant users to work simultaneously on the same patch hosted online.

Faust DSP programs can be dynamically compiled as objects included in the patch. An extended presentation of the system can be found in this IFC 2020 paper.

Brainwave Virtual Instrument

The Brainwave Virtual Instrument (BVI) is an open-source software synthesizer built in the programming language Faust. Its purpose is to facilitate the exploration of electroencephalogram (EEG) and other brain data through sonification. Pre-recorded data is translated as parameter controls of the instrument in the form of Open Source Control (OSC) messages that are generated and streamed by a small python program.

The instrument can easily be distributed and compiled to different targets thanks to Faust’s flexibility. Frequency Modulation synthesis provides a comprehensive approach to textural parameters of sounds, so that musical composition and improvisation based on a creative use of brain data become feasible. This is exemplified by the Brainwave Etudes (BE), a series of compositions inspired by measurements of brain activity during different states of mind.

The BVI was created for two major purposes: on the one hand, to find musical structures that relate to each other in order to present an aesthetic proposal, and on the other, to create a tool that familiarizes scientists and researchers in the field of neuroscience with sonification techniques, and the exploration of brain activity through sound. An extended presentation of the system can be found in this IFC 2020 paper.

Processing effect is written in Faust programming language and compiled into C code. So far the Cortex M4 core clocked at 204 MHz has proven to be capable of executing relatively complex effects like wah, but effect-chaining quickly reaches the limits of processing power.

Tambura

Waveguide physical model of an Indian Tambura/Tanpura. This is a FAUST patch inspired by the Indian Tambura/Tanpura - a four string drone instrument, known for its unique rich harmonic timbre.

The model uses a few tricks to produce a Tambura-like sound, and should probably be referred to as a "pseudo" physical model, because it does not attempt to accurately recreate the physics of the string-bridge interaction. It includes a range of parameters selected to allow control of the qualities of the excitation/pluck, string behavior and sympathetic resonance. It can produce some beautiful evolving drones, which can vary from very synthetic to quite natural. The model can be tested here.

Several DSP effects (compressor, freeverb, zitarev, limiter) are written in Faust, compiled as C++ code, and included in project sources.

Level Rider

This is an audio plugin written in Faust that automates gain level adjustments, based on a target gain level, a time window over which overall loudness is calculated via RMS, and a maximum adjustment threshold.

This plugin is comparable to Waves Vocal Rider or Waves Bass Rider in its functionality, but is free and open-source.

Whetstone Transient Shaper

A free, open source transient shaping audio plugin that operates on a specified frequency band. Whetstone will extract a certain frequency band based on a low cutoff and high cutoff that you choose, apply transient shaping to it, and then reintegrate the shaped band back into the original signal.

This plugin is meant to be comparable to the excellent Spiff plugin in its core functionality, but lacks many of the nice features and polished UI. The DSP is coded in Faust.

Reverb Trickery

A free, open source audio plugin implementing various creative reverb effects, including octave-shifted, distorted, hi-pass/low-passed, gated, and narrowing reverb, coded in Faust.

b259wf

This is a model of the "tibre" circuit of the Buchla 259 Complex Wave Generator, made in Faust. The model follows the circuit modelling as seen on the paper Virtual Analog Buchkla 259 wavefolder, using 5 folds.

The proposed 2-point BLAMP antialiasing method has been attempted for arbitrary sources as shown here, but it is not sufficient for high frequencies and/or more complex signals. Instead, filtering and light cubic nonlinearity distiorion has been used to round corners and for clipping.

The user interface consists of the controls fold for the folding amount, offset for offseting the signal before folding, and lowpass as a final stage one-pole filtering to control the character (too much folding might introduce unwanted higher harmonics for certain signals). The final output is dc-blocked.

string-machine

This is a virtual-analog string ensemble synthesizer. The implementation is based on a digital model designed by Peter Whiting. The improvement of the model adds various abilities, in particular a virtual-analog emulation of the bucket brigade delay circuit. Most of the DSP code is developed using Faust. Three VST or LV2 are generated: string-machine, string-machine-chorus and string-machine-chorus-stereo.

metaFx

The metaFx is a control surface for continuous sound transformations in real time, just like the metaSurface64.

Like metaSurface64, it has both its own loop generator and a multi-effects FX engine, but its operation is different, especially for the management of plugin chains and pads.

Each mixer on this surface can directly control the gain and the attached plug-ins. It is also possible to control the tracks of an external sequencer (Ardour or Reaper). To do this, the application uses OSC controllable modules that come from the Faust language library that is embedded in the application. Its interest lies in the construction of a parallel sound processing chain in the form of a graph.

Virtual Rhizome

By Vincent Carinola. Virtual Rhizome responds to a proposal by Christophe Lebreton and Jean Geoffroy to compose a work for the original Smart Hand Computer system, developed at the GRAME-CNCM using the Faust language and allowing to play smartphones as an instrument.

The work takes the form of a labyrinth, a kind of virtual architecture that could be compared to Borges' "garden of branching paths", within which the musician evolves by adapting his gestures to the constraints of different types of situations. Each situation is characterized by an autonomous functioning of the system, that the musician must apprehend in order to find the key allowing him to modify it and to move towards another situation. But in order to orientate himself well, he must create a mental representation of the structure of the work. The performer then becomes an explorer of a world that he unveils, but isn't that what he has always been?

Virtual rhizome owes much to the availability and enthusiasm of Jean Geoffroy and Christophe Lebreton. It is amicably dedicated to them.

SmartFaust

SmartFaust is a concept of musical applications for smartphones. These applications have the particularity of only using the user's gestures and not by tapping on the device's screen. Made for iOS and Android, they can also use the motion sensors of these devices to make them real musical instruments.

Smartfaust applications are based on the Faust (Functional Audio Stream) programming language developed by Grame over the last 15 years and recognized as a standard in the field of real-time signal processing for audio.

The SmartFaust applications were first used for the creation of the pieces Mephisto (for drums and cell phone ensemble), Belzebuth (participative piece for public equipped with Smartphones), Iblis (for clarinet and cell phone ensemble) and Bélial (for harp and cell phone ensemble) written by the composer Xavier Garcia.

From this same technology were later created the applications "Geek Bagatelles" (2016) and "GameLan" (2019).

Trombone Simulator

This simulator is a physical model of a trombone. Physical models of the lips, mouthpiece, slide, and bell are digitally simulated. The controls are listed at the top. The main controls are to move the cursor (or your finger on a touch device) left and right on the picture to adjust the embouchure, and up and down to extend and retract the slide. The diagonal colored lines are a guide to where the resonances are: playing over a resonance means that the embouchure and slide length are matched. Playing over white space means that one is between resonances and the note quality won't be as good. The big gray wedge on the upper right indicates that the resonances are very close together there. The vertical dashed lines indicate the rough locations of B-flat (thick lines) and F (thin lines). Other notes are unmarked, and likewise the slide positions. (Just like on a real trombone!) The off-key resonances (7th, 11th, 13th, and 14th) are marked in red. The g and f keys can be used to growl and flutter-tongue, respectively.

The audio simulation is written in Faust, which conveniently compiles to WebAssembly and a Web Audio API wrapper. The overall approach used was a digital waveguide model, as described in J. O. Smith III's Digital Waveguide Theory. The lips and bell are adapted from F. Scott's masters thesis.

Radium

Radium is a music editor with a new type of interface. It includes a Faust audio DSP development environment.

• Compared to the normal sequencer interface editing is quicker and more musical data fits on the screen.
• Compared to trackers, note positions and effects are edited graphically, which should be quicker, provide more vertical space and give a better musically overview. (Everything can also be edited by text, like in a normal tracker)
• Radium can also be used as a normal multitracker to mix and record audio.

HOA Library

HOA Library allows musicians and composers to synthesize, transform and render sound fields in a creative and artistic way. This library facilitates the understanding and the appropriation of key concepts of ambisonics. Thanks to original graphical interfaces a lot of new signal processings are allowed like diffuse sound field synthesis, perspective distorsion or spatial filtering. HOA library is open-source and free and offers a set of C++ and FAUST classes and implementation for Max, PureData and Unity.

Ambitools

Ambitools is a collection of plug-ins and tools for 3D sound field synthesis using Higher Order Ambisonics (HOA). The plugins are written in the Faust language, which allows them to be compiled for a multitude of architectures and platforms (Windows, Mac, Linux, WebAudio, embedded systems, etc.)

Moreover, the code is written in a scalable way: there is no limit to the maximum Ambisonic order! Other tools are also available, such as a 3D Visualizer written in the Processing language.

Ambisonic Decoder Toolbox

The Ambisonic Decoder Toolbox is a collection of MATLAB and GNU Octave functions for creating Ambisonic Decoders. Currently, it implements: (1) the AllRAD design technique, (2) inversion or mode-matching, (3) truncated mode-matching, constant energy, (4) linear combinations of 2 and 3, and (5) Slepian function basis (EPAD). The DSP code is written in MATLAB and Faust.

Ambisonic.xyz

A set of tools around Ambisonics.

FaustPy

FaustPy is a Python wrapper for Faust. It is implemented using the CFFI and hence creates the wrapper dynamically at run-time.

Rebel Technology

The OWL Pedal is an open source, programmable stage effects pedal, made for guitarists, musicians, hackers and programmers. Users can program their own effects, or download ready-made patches from our growing online patch library.

faust-vst

This project provides a VST plugin architecture for the Faust programming language. The package contains the Faust architecture, faustvst.cpp, the faust2faustvst helper script which provides a quick way to compile a plugin, a collection of sample plugins written in Faust, and a generic GNU Makefile for compiling and installing the plugins.

faust-lv2

This project provides an LV2 plugin architecture for the Faust programming language. The package contains the Faust architecture and templates for the needed LV2 manifest (ttl) files, a collection of sample plugins written in Faust, and a generic GNU Makefile as well as a shell script to compile plugins using the architecture.

RDK

Reverb Design is about creating a spacial impression aimed at sweetening the listening experience for a given context. The ambiguity of auditory and visual cues in reproduced sound makes it necessary to create an auditory illusion: To make this illusion work, I propose an aesthetic concept of simplicity and intelligibility based on psychoacoustic facts and recording practice as professional producer.

Foo YC20

The Foo YC20 is an open source implementation of the Yamaha YC-20 combo organ from 1969. Processing for the organ is based on original schematics and measurements from a working specimen. This instrument simulates the circutry as a whole to realisticly reproduce the features and flaws of the real deal.

FaucK

FaucK is a Chugin allowing to combine the powerful, succinct Functional AUdio STream (Faust) language with the strongly-timed ChucK audio programming language. FaucK allows programmers to on-the-fly evaluate Faust code directly from ChucK code and control Faust signal processors using ChucK's sample-precise timing and concurrency mechanisms. The goal is to create an amalgam that plays to the strengths of each language, giving rise to new possibilities for rapid prototyping, interaction design and controller mapping, pedagogy, and new ways of working with both Faust and ChucK.

Snd-RT

Snd-RT is the realtime extension for the sound editor SND and consists of two parts:

• the RT Engine - An engine for doing realtime signal processing.
• the RT Compiler - A compiler for a scheme-like programming language to generate realtime-safe code understood by the RT Engine.

Pure Language

[Pure is a modern-style functional programming language based on term rewriting. It offers equational definitions with pattern matching, full symbolic rewriting capabilities, dynamic typing, eager and lazy evaluation, lexical closures, built-in list and matrix support and an easy-to-use C interface. The interpreter uses LLVM as a backend to JIT-compile Pure programs to fast native code. It has been created by Albert Gräf.

pd-faust is a collection of Pd objects written using pd-pure which lets you run Faust programs inside Pd. It combines the functionality of pure-faust and faust2pd in a single package, and also features dynamic reloading of Faust plugins, automatic generation of controller GUIs and MIDI/OSC controller mappings, as well as OSC-based controller automation. It thus provides a complete solution for interactively developing Faust dsps in Pd.
