id3lib is/was a software library for reading, writing, and manipulating ID3v2 tags. Additionally it is possible to get some basic mp3 header information like bitrate etc. However, we now recommend moving to taglib. https://taglib.org/

Nyquist is a language for sound synthesis and music composition. It is implemented in C and C++ and runs on Win32, OSX, and Linux. Nyquist combines a powerful functional programming style with efficient signal-processing primitives. Nyquist is also embedded as a scripting language in Audacity.

SuperCollider is a platform for audio synthesis and algorithmic composition, used by musicians, artists, and researchers working with sound. It is free and open source software available for Windows, macOS, and Linux. scsynth, a real-time audio server, forms the core of the platform. It features 400+ unit generators (“UGens”) for analysis, synthesis, and processing. Its granularity allows the fluid combination of many known and unknown audio techniques, moving between additive and subtractive synthesis, FM, granular synthesis, FFT, and physical modeling. You can write your own UGens in C++, and users have already contributed several hundred more to the sc3-plugins repository. sclang, an interpreted programming language. It is focused on sound, but not limited to any specific domain. sclang controls scsynth via Open Sound Control. You can use it for algorithmic composition and sequencing, finding new sound synthesis methods, connecting your app to external hardware.

30 modules, 300+ Synthedit prefabs ranging from subcontrol circuits to synths, fsu effects, drum sequencers, near complete copy/paste/save/load system for xox style patterns. 2 complete vst effects, and one vst synth.

N.B. SuperCollider is now hosted at GitHub, and the most recent versions can be downloaded from there. http://supercollider.github.io A real time audio synthesis engine, and an object-oriented programming language specialised for music. SuperCollider was created in 1996 by James McCartney, now (since version 3) released as free software.

libxspf (formerly called "libSpiff") brings XSPF playlist reading and writing support to your C++ application. Both version 0 and 1 are supported. libxspf is the official reference implementation for XSPF of the Xiph.Org Foundation.

Drumstick is a tool to play music. This is a set of C++ MIDI libraries using Qt5 objects, idioms and style. It contains a C++ wrapper around the ALSA library sequencer interface; ALSA sequencer provides software support for MIDI technology on Linux. A complementary library provides classes for SMF (Standard MIDI files: .MID/.KAR), and Cakewalk (.WRK) file formats processing. A multiplatform realtime MIDI I/O library is also provided.

The Open VXI VoiceXML interpreter is a portable open source library that interprets the VoiceXML dialog markup language. It is designed to serve as a reference for parties interested in understanding how VoiceXML markup might be executed.

This library allows you to easily send and receive MIDI messages on the Arduino serial port. The purpose of this library is not to make a big MIDI controller or synth out of an Arduino board, but to help you do it, the application remains yours. /!\ PLEASE NOTE /!\ Project is hosted on GitHub: https://github.com/FortySevenEffects/arduino_midi_library This SourceForge project is deprecated.

The FFDec project intends to build a simple programming interface as one single DLL for video/audio-decoding using the FFmpeg library, so that it can be easily used in other programing languages - especially in Delphi and Free Pascal.

NOTE: The library code compatible with audacity has migrated to https://github.com/claytonotey/libsbsms A subband sinusoidal modeling library/command line tool/gui for time stretching and pitch scaling audio. Download the sbsms package for the source or the win32/mac wxSBSMSPlayer package for the gui binaries.

This project covers the development of 3rd-party tools for the "Wilson S1MP3 Player", some chinese device manufactured by Actions, with very low customer support. Generally you will find here development tools to access and alter the device firmware.

This project develops an open source editor for Clavia Nord Modular and Micro Modular synthesizers.

An automation plugin for Winamp. This exposes a lot of winamp functionality through COM / ActiveX. You may use this to write VB or .NET or any other applications which interact with Winamp. Also supports internal script hosting.

A C and C++ Library + a compiler to create Adobe Flash SWF movies up to version 9 (v1.8.1). Supports nearly all the tags, includes an ActionScript compiler. Detailed docs and other tools: convert fonts to Flash, decompile Flash, jpg2swf. LASTEST IS 1.8.4
