ChucK ~ Music Programming Language


ChucK is a programming language for real-time sound synthesis and music creation. It is open-source and freely available on MacOS X, Windows, and Linux. ChucK presents a unique time-based, concurrent programming model that’s precise and expressive (we call this strongly-timed), dynamic control rates, and the ability to add and modify code on-the-fly. In addition, ChucK supports MIDI, OpenSoundControl, HID device, and multi-channel audio. It’s fun and easy to learn, and offers composers, researchers, and performers a powerful programming tool for building and experimenting with complex audio synthesis/analysis programs, and real-time interactive music.

Surge ~ Subtractive Hybrid Synthesizer


This is the synthesizer plug-in Surge which (@kurasu) Claes Johanson previously sold as a commercial product via the company vember audio.

As he is too busy with other projects and no longer wanted to put the effort into maintaining Surge across multiple platforms, he decided to give it new life as an open-source project.

It was originally released in 2005, and was one of Claes’ first bigger projects. It is reliable and sounds great.

FluidSynth ~ A SoundFont Synthesizer


FluidSynth is a real-time software synthesizer based on the SoundFont 2 specifications and has reached widespread distribution. FluidSynth itself does not have a graphical user interface, but due to its powerful API several applications utilize it and it has even found its way onto embedded systems and is used in some mobile apps.

Features:

  • Cross platform support (Linux, macOS and Windows to name a few)
  • SoundFont 2 support
  • SoundFont 3 support (vorbis-compressed SF2)
  • Realtime effect control using SoundFont 2.01 modulators
  • Playback of MIDI files
  • Shared library which can be used in other programs
  • Built in command line shell

eSpeak ~ Open Source Speech Synthesizer


eSpeak is a compact open source Linux and Windows speech synthesizer for English and other languages. eSpeak uses a “formant synthesis” method. This allows many languages to be provided in a small size. The speech is clear, and can be used at high speeds, but is not as natural or smooth as larger synthesizers which are based on human speech recordings.

eSpeak is available as:

  • A command line program (Linux and Windows) to speak text from a file or from stdin.
  • A shared library version for use by other programs. (On Windows this is a DLL).
  • A SAPI5 version for Windows, so it can be used with screen-readers and other programs that support the Windows SAPI5 interface.
  • eSpeak has been ported to other platforms, including Android, Mac OSX and Solaris.

amsynth ~ Analog Modelling Synthesizer


amsynth is an easy-to-use software synth with a classic subtractive synthesizer topology.

  • Dual oscillators (sine / saw / square / noise) with hard sync
  • 12/24 dB/oct resonant filter (low-pass / high-pass / band-pass / notch)
  • Mono / poly / legato keyboard modes
  • Dual ADSR envelope generators (filter & amplitude)
  • LFO which can modulate the oscillators, filter, and amplitude
  • Distortion and reverb
