Open Source ChromeOS Sound Synthesis Software

A programmable audio generator intended as an aural aid to meditation, implementing the binaural beat principle as described in Gerald Oster's Oct. 1973 Scientific American article "Auditory Beats in the Brain."

A multi-platform software synthesiser emulating (somewhat inaccurately) pre-GM MIDI devices such as the Roland MT-32, CM-32L, CM-64 and LAPC-I. In no way endorsed by or affiliated with Roland Corp. Source hosted at: http://www.github.com/munt/

Psycle is a Music tracker (like FastTracker 2 or Impulse Tracker) combined with plugin modularity. It supports its own plugin API, the VST2 plugin standard, and a tracker style sampler playback.

SPTK is a suite of speech signal processing tools for UNIX environments, e.g., LPC analysis, PARCOR analysis, LSP analysis, PARCOR synthesis filter, LSP synthesis filter, vector quantization techniques, and other extended versions of them.

Frinika is a free, complete music workstation software for Linux, Windows, Mac OSX and other operating systems running Java. It features sequencer, soft-synths, realtime effects and audio recording.

Standing Wave 3 is an ActionScript 3 audio library that provides high-level control over the Flash Player’s SampleDataEvent API for streaming audio output. It builds on the foundation of Standing Wave 2 but has been extensively refactored, with its core sample storage and manipulation routines rewritten using Adobe Alchemy for significant performance improvements. Originally derived from the audio engine used in the Noteflight Score Editor, the library allows developers to combine and chain together audio sources, filters, and sequences to create dynamic, real-time sound experiences. Supported audio sources include MP3s, WAV files, and algorithmic generators, while filters enable effects such as echo, equalization, and envelope shaping. The system is flexible enough to handle complex timing sequences of audio, making it suitable for advanced audio applications or interactive projects.

A java front-end for LinuxSampler

The Analysis & Resynthesis Sound Spectrograph analyses a sound file into a spectrogram and is able to synthesise this spectrogram, or any other user-created image, back into a sound.

Just download the above zip file, extract it and then open the respective index.html file on your favourite internet browser and follow the instructions shown.

CWStudio is a portable almost library-independent and computationally efficient generator of CW signals for telegraphy training purposes. It can create a sound with maximum similarity to the real air, simulating many difficulties.

The CLUNK C++ library provides support for real-time 3D(binaural) sound generation. It puts virtually no limitations on the developer; people who have experienced working with other solutions (such as SDL_Mixer or Creative OpenAL) will respect this advan

A unique desktop music composing application for PC/Mac/Linux/Android with a tracker style interface and a simple modular Java plugin based design allowing rapid improvement and endless expansion.

This kangaroo-themed program allows the user to create their own music and sound effects, effectively from scratch. There are two variants of the program: Kangas Sound Editor which requires MySQL for its database, and Kangas Sound Editor QI which does not (it uses an internal database - HSQLDB - instead). Kangas Sound Editor (QI) uses a system of boxes or cells, which are placed by the user onto a timeline using drag-and-drop, and which represent entities such as chords, repetition, and individual sounds or notes. The program's database allows the user to create and store harmonics, used for constructing melodic instruments, and anti-harmonics, which are used for constructing percussion instruments. Users can collaborate with and build on the work of others via an XML import/export facility.

Portable command line utility for encoding and recording audio signals (chirps) to set the speed, incline, and resistance functions of iFit technology equipped exercise machines. Writes generated settings signals to music file format.

The Tibetan and Himalayan Library has several open-sourced tools for inputting, manipulating, translating, and transcribing Tibetan-language text, audio, and video. We aim to make using a computer easier for Himalayan peoples and scholars.

".ECW file" or "waveset" refers to a file with an extension of ".ECW" which stores articulation and sample data used by the MIDI synthesizer of sound cards equipped with an ES1370, ES1371, or ES1373 chip. These sound cards include the Ensoniq AudioPCI, the Sound Blaster! AudioPCI, the Sound Blaster! PCI64, the Sound Blaster! PCI128, and the Sound Blaster Live!. This project is a Perl script which can unpack these files into a .WAV sample, and a corresponding .SFZ file (an open format used by various sample engines to describe sample playback.)

Loris is a library for sound analysis, synthesis, and morphing, developed by Kelly Fitz and Lippold Haken at the CERL Sound Group. Loris includes a C++ class library, Python module, C-linkable interface, command line utilities, and documentation.

Implementation of the WSOLA algorithm for time scale modification of audio without artifact introduction (ideally). It allows one to speed/slow audio without altering its pitch.

A utility that can modify wav files to change the playing time of an audio clip, and transpose or scale the pitch of the clip. Great for audio book enthusiasts, and music lovers. Time shifting. DSP. Pitch Scaling.

Application which detects musical notes from the microphone. It allows listening to the microphone and play the detected notes to output (in midi). Multilanguage support. Zoom Dark mode option JDK-17 compatibility With v1.2 it includes a pitch shifter (making voice lower or sharper through a slider) There is a demo video which shows how it works (the demo video can be visited from Help menu of the application) You can also see the pitch-shifter demo version here: https://frojasg1.com:8443/resource_counter/resourceCounter?operation=countAndForward&url=https%3A%2F%2Ffrojasg1.com%2Fdemos%2Faplicaciones%2FInstrumentalMusic%2Fpitch.shifter.mp4%3Forigin%3Dsourceforge&origin=web
