FluidSynth, formerly named iiwusynth, is a free open source software synthesizer which converts MIDI note data into an audio signal using SoundFont technology without need for a SoundFont-compatible soundcard. FluidSynth can act as a virtual MIDI device, able to receive MIDI data from any program and transform it into audio on-the-fly. It can also read in SMF (.mid) files directly. On the output side, it can send audio data directly to an audio device for playback, or to a Raw or Wave file. It can also convert a SMF file directly to an audio file in faster-than-real-time. The combination of th
FluidSynth generates audio by reading and handling MIDI events from MIDI input devices by using a SoundFont. It is the software analogue of a MIDI synthesizer. FluidSynth can also play MIDI files. If you are missing parts of the documentation, let us know by writing to our mailing list. Of course, you are welcome to edit and improve the wiki yourself. All you need is an account at GitHub. Alternatively, you may send an EMail to our mailing list along with your suggested changes. Further information about the mailing list is available in the wiki as well. For information on how to build FluidSynth from source, please refer to our wiki. The synthesizer grew out of a project, started by Samuel Bianchini and Peter Hanappe, and later joined by Johnathan Lee, that aimed at developing a networked multi-user game. Sound (and music) was considered a very important part of the game. In addition, users had to be able to extend the game with their own sounds and images. Johnathan Lee proposed to use the Soundfont standard combined with intelligent use of midifiles. The arguments were: Wavetable synthesis is low on CPU usage, it is intuitive and it can produce rich sounds Hardware acceleration is possible if the user owns a Soundfont compatible soundcard (important for games!) MIDI files are small and Soundfont2 files can be made small thru the intelligent use of loops and wavetables. Together, they are easier to downloaded than MP3 or audio files. Graphical editors are available for both file format: various Soundfont editors are available on PC and on Linux (Smurf!), and MIDI sequencers are available on all platforms. In order to make Soundfonts available on all platforms (Linux, Mac, and Windows) and for all sound cards, we needed a software Soundfont synthesizer. That is why we developed FluidSynth.

FluidSynth, formerly named iiwusynth, is a free open source software synthesizer which converts MIDI note data into an audio signal using SoundFont technology without need for a SoundFont-compatible soundcard. FluidSynth can act as a virtual MIDI device, able to receive MIDI data from any program and transform it into audio on-the-fly. It can also read in SMF (.mid) files directly. On the output side, it can send audio data directly to an audio device for playback, or to a Raw or Wave file. It can also convert a SMF file directly to an audio file in faster-than-real-time. The combination of these features gives FluidSynth the following major use cases: Synthesizing MIDI data from another application directly to the speakers, Synthesizing MIDI data from another application, recording the output to an audio file, The MIDI data for either of the above can be received from an application, or a MIDI controller device (e.g keyboard / pads) attached to the computer (e.g. USB or Bluetooth) or received over a network, Playing a MIDI file to the speakers, Converting a MIDI file to a digital audio file.
thumb|Qsynth frontend The size of loaded SoundFont banks is limited by the amount of RAM available. There is a GUI for FluidSynth called Qsynth, which is also open source. Both are available in most Linux distributions, and can also be compiled for Windows. Windows binary installers are not distributed alone and are bundled with QSynth.
