Applications and libraries/Music and sound

This page contains a list of libraries and tools in a certain category. For a comprehensive list of such pages, see Applications and libraries.

Applications

hmp3

hmp3 is a curses-based mp3 player frontend to mpg321 and mpg123. It is written in Haskell. It is designed to be simple, fast and robust. It's very stable, with one instance running for several months.

minstrel

Minstrel is a curses frontend to the GStreamer library written in Haskell.

hxine

A console frontend to the xine library

HOgg

A library for handling the Ogg container format. Note that this just deals with the Ogg container, not with the contained Vorbis audio or Theora video etc. Includes a commandline tool (hogg) for querying files, merging and ripping tracks, hexdumping packets and pages and so on.

Libraries

Music composition

The Haskore Computer Music System

Haskore is a collection of Haskell modules designed for expressing musical structures in the high-level, declarative style of functional programming. Haskore is a means for describing music - in particular Western Music - rather than sound. It is not a vehicle for synthesizing sound produced by musical instruments, for example, although it does capture the way certain (real or imagined) instruments permit control of dynamics and articulation. Haskore compositions can be translated into various audible formats like MIDI, CSound and SuperCollider. (Former versions in LISP could generate traditional notation output, but this is currently not available in the Haskell version.)

Haskore related projects

HasChorus

A set of Haskell modules written on top of Haskore to make it easier to sequence simple, repetitive music.

MIDI processing libraries, both for MIDI file handling and real-time MIDI

Signal processing

HaskellDSP

Signal processing coded in Haskell. Contains also some matrix and stochastic computations which are required for signal processing.

Now managed with darcs repository, shipped via Hackage.

Synthesizer library

Signal processing related to audio effects coded in plain Haskell. There is both a low-level interface and a framework for automatical inference of sample rate and amplitude of signals in a sound processing network. This generalizes the usual restricted splitting into audio rate and control rate signals. There is an interface for using synthesized sounds for rendering Haskore music. Recent versions require Numeric Prelude. See an early paper on the concepts. Highly experimental.

YampaSynth

Modular synthesizer using Yampa. Can process SoundFont files. There was a presentation at Haskell Workshop 2007 in Freiburg, Germany, of which a video was recorded.

Wrappers

HOpenAL

A Haskell Binding for OpenAL and ALUT. The goal of this project is to provide a binding for OpenAL, a cross-platform 3D audio API, appropriate for use with gaming applications and many other types of audio applications.

hsSDL

Contains bindings to libSDL, libSDL_gfx, libSDL_image, libSDL_mixer and libSDL_ttf.

JACK and ALSA wrappers by Sönke Hahn

SuperCollider by Rohan Drape

Interface to the realtime software synthesizer SuperCollider. Experimental. Includes widely useful OpenSoundControl module.

CSound

HLADPSA

A port of LADSPA (Linux Audio Developer's Simple Plugin API) to Haskell. Still highly experimental. The project can be regarded as an example of how to create plugins and shared libraries in Haskell without making use of hs-plugins.

MPD client library

A client library for controlling an MPD server.

OpenAL

OpenAL (short for Open Audio Library) is a library for creation of a virtual 3D world of sound.

ALUT

The OpenAL Utility Toolkit (ALUT) is an extension to OpenAL

Data formats

Different sound libraries use different in-memory data formats. For a summary by category, see Applications and libraries/Music and sound/Formats.
