  • https://en.wikipedia.org/wiki/Comparison_of_audio_synthesis_environments - typically consist of an audio programming language (which may be graphical) and a user environment to design/run the language in. Although many of these environments are comparable in their abilities to produce high-quality audio, their differences and specialties are what draw users to a particular platform. This article compares noteworthy audio synthesis environments, and enumerates basic issues associated with their use.




  • https://en.wikipedia.org/wiki/Digital_filter - a system that performs mathematical operations on a sampled, discrete-time signal to reduce or enhance certain aspects of that signal. This is in contrast to the other major type of electronic filter, the analog filter, which is an electronic circuit operating on continuous-time analog signals.A digital filter system usually consists of an analog-to-digital converter (ADC) to sample the input signal, followed by a microprocessor and some peripheral components such as memory to store data and filter coefficients etc. Program Instructions (software) running on the microprocessor implement the digital filter by performing the necessary mathematical operations on the numbers received from the ADC. In some high performance applications, an FPGA or ASIC is used instead of a general purpose microprocessor, or a specialized digital signal processor (DSP) with specific paralleled architecture for expediting operations such as filtering. Digital filters may be more expensive than an equivalent analog filter due to their increased complexity, but they make practical many designs that are impractical or impossible as analog filters. Digital filters can often be made very high order, and are often finite impulse response filters which allows for linear phase response. When used in the context of real-time analog systems, digital filters sometimes have problematic latency (the difference in time between the input and the response) due to the associated analog-to-digital and digital-to-analog conversions and anti-aliasing filters, or due to other delays in their implementation. Digital filters are commonplace and an essential element of everyday electronics such as radios, cellphones, and AV receivers.

  • Fiview - freeware application for Windows, Linux and Mac OSX that can be used to design and view digital filters. It also makes it very easy to compare different filters by allowing you to switch between them using the digit keys, and it generates efficient and readable public domain example code that can be used directly in an application. It is released under the GNU GPL. Much of the underlying filter design code was based on mkfilter from Tony Fisher -- see the source code for details. The resulting filters were improved by splitting them into separate stages, which improves the accuracy and stability of them enormously, especially for higher-order Bessel and Butterworth filters. The source also includes a library, fidlib (now with its own page), which can be used to design filters at run-time. The fiview utility generates fast generic compiler-optimisable example C code both using the frequencies provided, and also in a form that allows the frequencies to be provided at run-time via a call to fidlib. This permits applications the flexibility to do things like generating banks of similar filters at run-time according to run-time parameters.


  • MicroModeler DSP - a web-based digital filter IDE. MicroModeler DSP solves the entire filter design, scaling and coding problem in one integrated process. Spend less time on the problems and more time on your project.


  • Polarbear - a tool for designing filters in the complex domain. Filters can be designed by placing any number of poles and zeros on the z plane. From this the filter coefficients are calculated, and the filter can be applied in real time on an audio stream.


  • FFmpegSource - (usually known as FFMS or FFMS2) is a cross-platform wrapper library around FFmpeg/libav. It gives you an easy, convenient way to say "open and decompress this media file for me, I don't care how you do it" and get frame- and sample-accurate access (usually), without having to bother with the sometimes less than straightforward and less than perfectly documented libav API.

Historical

MUSIC-N

1957

  • https://en.wikipedia.org/wiki/MUSIC-N - refers to a family of computer music programs and programming languages descended from or influenced by MUSIC, a program written by Max Mathews in 1957 at Bell Labs. MUSIC was the first computer program for generating digital audio waveforms through direct synthesis. It was one of the first programs for making music (in actuality, sound) on a digital computer, and was certainly the first program to gain wide acceptance in the music research community as viable for that task.

The world's first computer-controlled music was generated in Australia by programmer Geoff Hill on the CSIRAC computer which was designed and built by Trevor Pearcey and Maston Beard. However, CSIRAC produced sound by sending raw pulses to the speaker, it did not produce standard digital audio with PCM samples, like the MUSIC-series of programs.

Less obviously, MUSIC can be seen as the parent program for: RTSKED (a later RealTime Scheduling language by Max Mathews), Max/MSP, Pure Data, AudioMulch, SuperCollider, JSyn, Common Lisp Music, ChucK, or any other computer synthesis language that relies on a modular system (e.g. Reaktor).

  • Music N – Musica Informatica - Music N is an acronym, coined retrospectively, by which commonly indicates a set of computer music languages, developed over forty years. Although made by different people and in different contexts, these languages have in common certain characteristics that have led, in fact, to speak of a single family membership.
MUSIC-V

1969

  • Music V – Musica Informatica - Music V is a sound synthesis software. It is among the best known of the Music N family of computer music programming language. Certainly the first one that had a spread beyond the boundaries of the United States. Ported to a PDP10, Music V became the Mus10 music compiler system and played scores composed in Leland Smith's SCORE language.



MUSIC-10


SCORE


  • SCORE-11 was originally designed for Vercoe’s MUSIC11 system. MUSIC11, which was written in PDP-11 assembly language, was replaced in 1986 by CSOUND, a version of the program written in the programming language C, and which runs on many different computer systems. SCORE-11 works well with either version of Vercoe’s program, which will be referred to as CSOUND in this manual except where the distinction is important.

SCORE-11 (Brinkman, 1981 & 1990) is a note-list preprocessor for the CSOUND compiler, which was written by Barry Vercoe at MIT. SCORE-11 was written by Alexander Brinkman of the Eastman School of Music. The SCORE-11 input syntax is based, with some important extensions, on the well known “SCORE” program (used on the Stanford-Ircam MUS10 system) by Leland Smith (Smith, 1972 & 1980). A composer who is familiar with either preprocessor will have no problems changing to the other one. This will reduce dependency on a specific music system. Some features of SCORE were not implemented in SCORE-11. These are mostly the features that allow data to be copied from one instrument block to another. Several features wer added to SCORE-11 to make it very powerful.

SCORE-11 is written in the PASCAL programming language, increasing its potential for exportability. You will find SCORE-11 to be of great help in the process of defining the hundreds of events that make up a composition. In the following pages you will find a comprehensive manual introducing and describing in detail the various features of SCORE-11.



Cmusic

  • Cmusic - developed in 1980 by Richard Moore at the Computer Audio Research Laboratory (CARL) of the Center for Music Experiment at the University of California at San Diego (UCSD). Moore, who had worked alongside Max Mathews for the development of GROOVE, at first had thought to create a new version of Music V but upgraded to the C language. Following preferred to prepare a completely new software.
  • https://github.com/vlazzarini/cmusic - the sources and makefiles for a build of the classic CARL cmusic and related programs. The build has been tested on OSX and Linux, and although a number of warnings are issued, it compiles and links successfully (but see 'Known issues')

SSSP

In designing the system, we decided early on to adopt a highly interactive approach to the design of the human interface. Batch processing as in Music V (Mathews: 1969) is an alternative, but one which widely separates the composer and the program, causing serious delays in the feedback loop. We feel a score editor must be interactive because there are facets of the task which demand control and aesthetic judgment by the composer in an interactive and exploratory manner. Several modes of interaction have previously been used in music systems, such as alphanumeric text as in MUSlC10 (Smith: 1978), voice recognition (Tucker, Bates, Frykberg, Howrath Kennedy, Lamb, Vaughan: 1977), and piano -type keyboard (New England Digital Corp.: 1978). In our work we have adopted a bias towards graphics -based interaction (Baecker: 1979; Newman and Sproull: 1979) in the belief that this approach can make a significant contribution towards an effective human interface. First, music lends itself well to representations in the visual domain. Second, the task of editing music is complex in the sense that there are many parameters and commands to be manipulated and controlled this complexity can be reduced by the graphic representation of information. Third, previous work (Pulfer: 1972; Tanner: 1972; Vercoe: 1975) indicates that more congenial interfaces can be constructed using dynamic graphics techniques.

SAMBOX

1977

The compiler was replaced in 1977 with dedicated synthesis hardware in the form of the Systems Concepts Digital Synthesizer (built by Peter Samson and known as the ``Samson Box). The Samson Box was capable of utilizing many types of synthesis techniques such as additive synthesis, frequency modulation, digital filtering and some analysis-based synthesis methods. The PLA language, written by Bill Schottstaedt, allowed composers to specify parametric data for the Samson Box as well as for other sound processing procedures on the PDP10 mainframe (and on its eventual replacement, a Foonly F4). On April 3, 1992, the Foonly and Samson Box were officially retired.

HMSL

  • https://en.wikipedia.org/wiki/Hierarchical_Music_Specification_Language - a music programming language written in the 1980s by Larry Polansky, Phil Burk, and David Rosenboom at Mills College. Written on top of Forth, it allowed for the creation of real-time interactive music performance systems, algorithmic composition software, and any other kind of program that requires a high degree of musical informatics. It was distributed by Frog Peak Music, and runs with a very light memory footprint (~1 megabyte) on Macintosh and Amiga systems.

Unlike CSound and other languages for audio synthesis, HMSL is primarily a language for making music. As such, it interfaces with sound-making devices through built-in MIDI classes. However, it has a high degree of built-in understanding of music performance practice, tuning systems, and score reading. Its main interface for the manipulation of musical parameters is through the metaphor of shapes, which can be created, altered, and combined to create a musical texture, either by themselves or in response to real-time or scheduled events in a score. HMSL has been widely used by composers working in algorithmic composition for over twenty years. In addition to the authors (who are also composers), HMSL has been used in pieces by Nick Didkovsky, The Hub, James Tenney, Tom Erbe, and Pauline Oliveros. A Java port of HMSL was developed by Nick Didkovsky under the name JMSL, and is designed to interface to the JSyn API.


Music Mouse

  • https://en.wikipedia.org/wiki/Music_Mouse - an algorithmic musical composition software developed by Laurie Spiegel. Spiegel's best known and most widely used software, "Music Mouse - An Intelligent Instrument" (1986) is for Macintosh, Amiga and Atari computers. The "intelligent instrument" name refers to the program's built-in knowledge of chord and scale convention and stylistic constraints. Automating these processes allows the user to focus on other aspects of the music in real time. In addition to improvisations using this software, Spiegel composed several works for "Music Mouse", including Cavis muris in 1986, Three Sonic Spaces in 1989, and Sound Zones in 1990. She continued to update the program through Macintosh OS 9, and as of 2012, it remained available for purchase or demo download from her website.

Image/ine

  • Image/ine - the first piece of software (for normal computers) that allowed users to manipulate uncompressed video in real time. Limited, at the time, to 320x240 pixels at some 10 frames per second (the Macintosh 8600 was the dream machine), it nevertheless proved a point: artistic quality and stage guts made lack of frame rate and image quality of secondary interest; real time video manipulation could be done! Soon others followed, all with their strengths and weaknesses. What set Image/ine apart, and sets ImX apart, is that this is software for video people, not for musicians and not for programmers.

Lisp

Common Music

1989

  • Common Music (CM) - a music composition system that transforms high-level algorithmic representations of musical processes and structure into a variety of control protocols for sound synthesis and display. Its main user application is Grace (Graphical Realtime Algorithmic Composition Environment) a drag-and-drop, cross-platform app implemented in JUCE (C++) and S7 Scheme. In Grace musical algorithms can run in real time, or faster-than-real time when doing file-based composition. Grace provides two coding languages for designing musical algorithms: S7 Scheme, and SAL, an easy-to-learn but expressive algol-like language.

Common Music can write scores in several different syntaxes (currently CLM, CMN, Music Kit, MIDI, CSound and Paul Lansky's real-time mixing program, RT). The scores can then be rendered on workstations using any of the target synthesis programs. For example, CLM (Common Lisp Music, written by Bill Schottstaedt) is a widely used and fast software synthesis and signal processing package that can make use of multiple Motorola 56001 DSPs.

Pla is the intellectual ancestor of CM.

Common Lisp Music

1997

  • CLM (originally an acronym for Common Lisp Music) is a sound synthesis package in the Music V family. It provides much the same functionality as Stk, Csound, SuperCollider, PD, CMix, cmusic, and Arctic — a collection of functions that create and manipulate sounds, aimed primarily at composers (in CLM's case anyway). The instrument builder plugs together these functions (called generators here), along with general programming glue to make computer instruments. These are then called in a note list or through some user interface (provided by Snd, for example).


  • https://github.com/defaultxr/cl-wav-synth - a wav sample editor. It comes in two parts, the main library for manipulating wav files and a (Mc)CLIM interface with a full lisp listener, a sample pane editor, a spectrum pane editor and a song pane editor.



cl-patterns

  • https://github.com/defaultxr/cl-patterns - A library for writing patterns to generate or process (a)musical sequences of mathematically (un)related (non-)compound values in Lisp.Put more simply, cl-patterns is a system for making music and noise via Lisp code.

Ronin

  • https://github.com/hundredrabbits/Ronin - a procedural graphics tool designed to automate simple graphical tasks, like resizing, cropping, coloring, and generating algorithmic images. It interprets a minimal dialect of LISP, look at the examples to better understand how this all works. The library updates is constantly revealing new applications to Ronin, you can see the list of available functions here. Most of our iconography and designs were created with both Ronin and Dotgrid.

Incudine

  • Incudine - useful to design software synthesizers or sound plugins from scratch, exploiting the expressive power of Common Lisp, without the constraint to use pre-built unit generators. It is also a compositional tool that allows to produce high quality sounds controllable at the sample level, defining and redefining the digital signal processors and the musical structures on-the-fly.Incudine introduces the Virtual UGen (VUG), a new mechanism for defining primitive unit generators by writing concise and reusable code. The definition of a VUG contains lisp code and/or other nested VUGs (or "real" UGens), and it is re-arranged and compiled efficiently during the creation of a DSP.

thundersnow

  • thundersnow - a work-in-progress digital audio workstation and live coding laboratory in Lisp.It builds upon cl-patterns' (non-)deterministic (non-)musical composition and performance functionality with a set of graphical control surfaces and visualizations, as well as bdef's audio buffer and analysis abstractions to quickly generate and wrangle musical data.Under the hood it should support any of the sound servers these libraries do, which include SuperCollider (via cl-collider) and Incudine. Its interface is structured using the Common Lisp Interface Manager for that classic, truly dynamic Lisp "feel".
  • https://github.com/defaultxr/thundersnow - Lisp/McCLIM-based digital audio workstation and live coding laboratory.

Csound

  • Csound - a sound and music computing system which was originally developed by Barry Vercoe in 1985 at MIT Media Lab. Since the 90s, it has been developed by a group of core developers. Although Csound has a strong tradition as a tool for composing electro-acoustic pieces, it is used by composers and musicians for any kind of music that can be made with the help of the computer. Csound has tradtionally being used in a non-interactive score driven context, but nowadays it is mostly used in in a real-time context. Csound can run on a host of different platforms incuding all major operating systems as well as Android and iOS. Csound can also be called through other programming languages such as Python, Lua, C/C++, Java, etc. [8]


  • https://en.wikipedia.org/wiki/Csound - Csound was originally written at MIT by Barry Vercoe, based on his earlier system called Music 11, which in its turn followed the MUSIC-N model initiated by Max Mathews at the Bell Labs. Its development continued throughout the 1990s and 2000s, led by John ffitch at the University of Bath. The first documented version 5 release is version 5.01 on March 18, 2006.





  • /chapter: A-The-Csound-Api - An application programming interface (API) is an interface provided by a computer system, library or application that allows users to access functions and routines for a particular task. It gives developers a way to harness the functionality of existing software within a host application. The Csound API can be used to control an instance of Csound through a series of different functions thus making it possible to harness all the power of Csound in one’s own applications. In other words, almost anything that can be done within Csound can be done with the API. The API is written in C, but there are interfaces to other languages as well, such as Python, C++ and Java.Though it is written in C, the Csound API uses an object structure. This is achieved through an opaque pointer representing a Csound instance. This opaque pointer is passed as the first argument when an API function is called from the host program.



  • https://github.com/gogins/cxx-opcodes - The CXX opcodes provide a means for Csound users to embed C++ source code in Csound orchestra code, and for Csound then to compile, load, link, and run C++ during the course of the Csound performance.
  • https://github.com/vlazzarini/opcode_compiler - experimental opcode builds on the initial work by Michael Goggins, and is based on the llvm/clang interpreter example code. It provides a just-in-time C module compiler, which can be used to add new opcodes to Csound on-the-fly.



Live Coding with Csound


PythonScore

  • PythonScore - a modular Csound score environment for event generation, event processing, and the fashioning musical structures in time.


CSoundQT

  • CsoundQt - a frontend for Csound featuring a highlighting editor with autocomplete, interactive widgets and integrated help. It is a cross-platform and aims to be a simple yet powerful and complete development environment for Csound. It can open files created by MacCsound. Csound is a musical programming language with a very long history, with roots in the origins of computer music. It is still being maintained by an active community and despite its age, is still one of the most powerful tools for sound processing and synthesis. CsoundQt hopes to bring the power of Csound to a larger group of people, by reducing Csound's intial learning curve, and by giving users more immediate control of their sound. It hopes to be both a simple tool for the beginner, as well as a powerful tool for experienced users.

  • p5.Csound - a lightweight wrapper to the web assembly build of Csound. It provides all the power of Csound inside p5.js sketches. With over a thousand processing opcodes, it is one of the most extensive audio processing libraries available in a browser. This interface provide very little in the way of wrapper functions. In fact, it only provides two. After that everything is accessible through the Csound object.

Cmix / RTcmix

  • RTcmix - An Open-Source, Digital Signal Processing and Sound Synthesis Language, one of the MUSIC-N family of computer music programming languages. RTcmix is descended from the MIX program developed by Paul Lansky at Princeton University in 1978 to perform algorithmic composition using digital audio soundfiles on a IBM 3031 mainframe computer. After synthesis functions were added, the program was renamed Cmix in the 1980s. Real-time capability was added by Brad Garton and David Topper in the mid-1990s, with support for TCP socket connectivity, interactive control of the scheduler, and object-oriented embedding of the synthesis engine into fully featured applications.

RTcmix has a number of unique (or highly unusual) features when compared with other synthesis and signal processing languages. For one, it has a built-in MINC parser, which enables the user to write C-style code within the score file, extending its innate capability for algorithmic composition and making it closer in some respects to later music software such as SuperCollider and Max/MSP. It uses a single-script instruction file (the score file), and synthesis and signal processing routines (called instruments) exist as compile shared libraries. This is different from MUSIC-N languages such as Csound where the instruments exist in a second file written in a specification language that builds the routines out of simple building blocks (organized as opcodes or unit generators). RTcmix has similar functionality to Csound and other computer music languages, however, and their shared lineage means that scripts written for one language will be extremely familiar-looking (if not immediately comprehensible) to users of the other language.


  • RT-cmix -- Using CMIX in Real Time - Several computer music "languages" intended to facilitate the coding of sound synthesis and signal-processing algorithms have become popular among practitioners of computer music (CSOUND, CMIX and CMUSIC, for example). Until quite recently, however, low-cost computing power was not available to allow these languages to run in real-time; instead the computer musician generally worked by reading and writing samples to and from disk files and listening to the results when computation was complete. Within the past few years smaller, general-purpose computers have become powerful enough to run digital sound synthesis and signal-processing algorithms in real time. This demonstration will show the capabilities of RTcmix, a set of extensions and modifications to the CMIX computer music language enabling it to function as a real-time programming environment. Included in the RTcmix package is a dynamic event scheduler and the ability to process disk files and external audio signals in real time. Thus RTcmix can be used to create interactive performance works in addition to providing a fast 'turnaround' for composers building tape-music pieces. Additional aspects of the package include a socket-based protocol for control of RTcmix by external processes, and "backwards compatibility" with all existing CMIX features and instruments. The implementation of RTcmix will be discussed in detail, as well as the rationale behind the design of the language. RTcmix is a unix-based language in the public domain, currently running under both Linux and IRIX.

  • Microtone - How tiny you ask? 128 bytes. The sound generation itself takes up just 14 lines of assembly, generating 31 bytes of machine code. The rest is taken up the ELF header and functions needed to open the sound device and outputting samples


  • Coding an Equalizer - This article expands the section on page 20 of my book The Audio Expert that describes briefly how digital equalizers work. As explained in the book, all equalizers are based on filters of various types. Computer code that implements a filter is called Digital Signal Processing, or DSP for short. Most digital filters emulate equivalent analog filters, and the common language for all filters is mathematics. Therefore, several trigonometry formulas are shown below, and there's no escaping this! But the basic operation of the computer code that implements an equalizer is not too difficult to follow, even if you don't understand the formulas. To keep this example as brief as possible, the code implements a simple high-pass filter having one pole (6 dB per octave). Formulas to implement other filter types including those used in parametric equalizers are shown on the Cookbook Formulae web page by Robert Bristow-Johnson.

The library consists of a set of high-level audio synthesis components (Oscillators, Filters, Envelopes, Delays, Reverbs, and other Utilities). Our primary use case is embedded audio computing on 32-bit ARM microcontrollers that can run "bare-metal" (without an OS), such as the STM32f4, STM32f7, and STM32H7. The code, however, is general enough to be used in many other situations as well. We have included a JUCE VST/AU generating template to test the library (2), and the python script we use to generate wavetables.

Most of these algorithms are sourced from other projects, especially the STK (Sound Toolkit) library and various discussions on the music-DSP mailing list. We also owe a lot to open source computer programming languages, such as C-sound, ChucK, PureData, and Supercollider. Other interesting projects to check out that similarly target embedded applicatons are: TeensyAudio (C++), Hoxton Owl (C++), Axoloti (C), and Mutable Instruments (C++).

Postfish

  • https://github.com/ePirat/Postfish - a digital audio post-processing, restoration, filtering and mixdown tool. It works as a linear audio filter, much like a rack of analog effects. The first stage of the filter pipeline provides a bank of configurable per-channel processing filters for up to 32 input channels. The second stage provides mixdown of the processed input audio into a group of up to eight output channels. The third stage applies processing filters to the output group post-mixdown. The Postfish is a stream filter; feed it audio from a list of files or input stream, and it renders audio to standard out, as well as optionally providing a configurable audio playback monitor via a sound device. If the input audio is being taken from files, Postfish also provides simple forward/back/cue seeking and A-B looping control. The next major update of Postfish will also include automation to allow mixdown settings to be 'recorded' and applied automatically during rendering.

JUCE C++ Library


old, to rework


  • https://en.wikipedia.org/wiki/JUCE - Like many other frameworks (e.g., Qt, wxWidgets, GTK+, etc.), JUCE contains classes providing a range of functionality that covers user-interface elements, graphics, audio, XML and JSON parsing, networking, cryptography, multi-threading, an integrated interpreter that mimics ECMAScript's syntax, and various other commonly used features. Application developers needing several third-party libraries may thus be able to consolidate and use only the JUCE library, or at least reduce the number of third-party libraries they use. In this, the original inspiration was Java's JDK, and JUCE was intended to be "something similar for C++".

A notable feature of JUCE when compared to other similar frameworks is its large set of audio functionality; this is because JUCE was originally developed as a framework for Tracktion, an audio sequencer, before being split off into a standalone product. JUCE has support for audio devices (such as CoreAudio, ASIO, ALSA, JACK, WASAPI, DirectSound) and MIDI playback, polyphonic synthesizers, built-in readers for common audio file formats (such as WAV, AIFF, FLAC, MP3 and Vorbis), as well as wrappers for building various types of audio plugin, such as VST effects and instruments. This has led to its widespread use in the audio development community.

JUCE comes with wrapper classes for building audio and browser plugins. When building an audio plugin, a single binary is produced that supports multiple plugin formats (VST & VST3, RTAS, AAX, Audio Units). Since all the platform and format-specific code is contained in the wrapper, a user can build Mac and Windows VST/VST3/RTAS/AAX/AUs from a single codebase.

NFSmartPlayer

  • https://github.com/spotify/NFSmartPlayer - We dreamed of an audio engine that could multitrack, stream long audio, apply audio effects, react to user input through a scripting layer, be resource-light, and work on the majority of platforms. We wanted to bring new audio experiences to both listeners and creators, without requiring a degree in audio engineering. We created a declarative format to describe the audio and effects over time, known as NFGrapher. This C++ smart player consumes JSON produced by NFGrapher, and outputs audio in either realtime to the audio driver or faster-than-realtime (offline to a file). Via NFDecoder and NFHTTP, it can stream audio files from the file system, over HTTP(S), or through DASH (HLS) transmuxing.

  • UGen - UGens represent calculations with signals. They are the basic building blocks of synth definitions on the server, and are used to generate or process both audio and control signals. The many subclasses of UGen are the client-side representations of unit generators, and are used to specify their parameters when constructing synth definitions (see SynthDef).
  • Writing Unit Generators - "SuperCollider has a vast library of unit generators that can be assembled in unlimited ways, but sometimes even those aren't sufficient. You may have a need for an unusual signal processing algorithm, or you're running into efficiency problems that can be solved by condensing parts of your SynthDef into a single UGen. UGens are defined in server plugins written in C++. Server plugins are not to be confused with quarks, which extend the SuperCollider language. UGens exist more or less independently of the interpreter and you don't need much familiarity with SC to write them. Writing UGens is not too difficult, but it's arguably far less convenient and intuitive than the high-level tools that SuperCollider provides. You'll need a build system and a good amount of boilerplate code -- even fairly basic signal processing operations can require a lot of code. You don't have an instant live coding environment, and mistakes can easily crash the server. SuperCollider's UGens are stable and well-tested, and custom UGens are best viewed as a last resort for when the limitations of SC are impassable."

  • PDF: FAUST : an Efficient Functional Approach to DSP Programming - Yann Orlarey, Dominique Fober and Stephane Letz. FAUST is a programming language that provides a purely functional approach to signal processing while offering a high level of performance. FAUST aims at being complementary to existing audio languages by offering a viable and efficient alternative to C/C++to develop signal processing libraries, audio plug-ins or standalone applications. The language is based on a simple and well formed formal semantics. A FAUST program denotes a signal processor, a mathematical function that transforms input signals into output signals. Being able to know precisely what a program computes is important not only for programmers, but also for compilers needing to generate the best possible code. Moreover these semantics questions are crucial for the longterm preservation of music programs. The following paragraphs will give an overview of the language as well as a description of the compiler, including the generation of parallel code.



  • Romain Michon - Faust Tutorials - This page gathers a series of tutorials around the Faust programming language wrote as part of various projects. It was not written in a "linear way", so each section is independent and covers a different topic. As a result, it is quite possible that you find some redundancy if you read this page from top to bottom. Should you have any question, feel free to send me an e-mail.






Tools


  • https://github.com/hrtlacek/faustTools - Tools for analyzing Faust programs. At the moment there is one tool present, faustwatch. Faustwatch is a tool that observes a .dsp file used by the dsp language FAUST. If the file is changed (saved after editing); the block diagram can be automatically shown in the default browser; the impulse response can be plotted in the time domain; the impulse response can be plotted in the frequency domain. The time and frequency domain plots of the last saved version are always visible so the current and last saved version can be compared. The impulse response is played back via pyo and JACK Audio. Basically it is supposed to make FAUST development faster.



  • https://github.com/droosenb/faust-wdf-library - in progress library for creating Wave Digital Filter based models for the Faust programming language, written entirely in faust. Currently the library only includes files and functions which are being tested for use in the eventual completed library.

Central to the Extempore programming environment is a new systems programming language designed to support the programming of real-time systems in real-time. xtlang is designed to mix the high-level expressiveness of Lisp with the low-level expressiveness of C. xtlang uses an s-expression syntax common to Lisp, and more particularly to Scheme. xtlang also borrows many Lisp like semantics including first class closures, tail recursion and macros. However, xtlang also borrows heavily from systems languages like 'C' including static typing, low-level type expressivity, direct pointer manipulation and explicit memory managment (i.e. no GC). xtlang then extends these 'C' semantics with type-inferencing, ad-hoc polymorphism, reified generics, and zone/region based memory management.

The MDAL syntax adheres to several key elements of tracker modules: Song structure is broken down into patterns, which are linked via a sequence matrix. Time flow is represented vertically. The concept of measures and note values has no direct representation in MDAL, instead note length is measured in steps and ticks.MDAL is a language without a pre-defined nomenclature. Aside from a rudimentary set of structural conventions, there are no fixtures - the entire instruction set is customizable. Customization is provided through standardized configuration files, which are parsed and interpreted by an MDAL compiler at runtime. This enables programmers to adapt both user input and data output to the specific needs of their sound drivers/player routines.
