byzorgan
Specialized sound synthesizer with Byzantine Church music scales
This software integrates a small, specialized synthesizer and vocal processor. It can be used to learn Byzantine Church singing. You can play from the keyboard, mouse or touch screen. MIDI input is also available. Voice functions include: pitch highlighting, synthesizer control by voice, pitch correction and voice-to-ison conversion. On the screen there are labels with symbols of Byzantine notes. There is a metronome. The program is oriented on the Chrysanthos tuning of the diatonic scale: 9/8 - 12/11 - 88/81. The octave is divided into 17 (or 19) non-equal parts, it allows you to get all the Byzantine modes. -

nbo-plugins
An entire virtual orchestra in LV2 plugin format
The No Budget Orchestra Plugins are a collection of virtual (software) musical instruments. comprising a full, classical orchestra There are flute, piccolo, oboe, bassoon, clarinet, violin, viola, cello, contrabass, trumpet, trombone, tuba, french horn, and various percussion sections. The various sections include articulations. For example, the violin section can play legato, pizzicato, staccato, and tremulo. There are subgroups as well, for example Violins I and II. The plugins are in LV2 (Linux) format for use in Ardour, Muse, QTractoor, etc. They are available in 2 formats; a collection of LV2 plugins, and a collection of linux executables. The plugins can be loaded into a host program such as Ardour, Muse, QTractor, etc. The executables are standalone versions that contain both the samples, and the engine that plays them. -

PerfectSineWaves
Perfect and bit-perfect PCM encoded sine wave audio test tones
In this project, a perfect PCM sine wave is one that contains a single frequency at 0 dBTP and no error harmonics at all. A bit-perfect PCM sine wave has error harmonics due to encoding quantization, but they are at the minimum level possible for the chosen encoding. The generated wave files hold a sequence of one or more complete copies of a repeating pattern. A file containing a single pattern can be played in a loop to extend the play time. Because most audio players don't loop cleanly, the included wave files contain enough complete patterns to play 2 minutes without looping. Every sinusoid in the file contains a whole number of cycles. This ensures clean looping and allows windowless FFT analysis. Each sinusoid in the file can have a unique phase and amplitude. The included wave file generation utility uses GNU MPFR library for extended precision floating point math and FFTW for verification. Output level is nearest possible to 0 dBTP without going over. -

MOLOSS
Hybrid Virtual Synthesizer
MOLOSS (Multi Oscillator Linear Open Source Synthesizer) is a virtual synth, available as a VST plugin or standandalone exe, to build analog vintage sounds by combining several techniques used in the 80's. Its 4 voices mix Subtractive synthesis, additive synthesis, frequency (or actually phase) modulation, cross modulation, to allow a very wide sound range, with a lightweight CPU load. It has a default polyphony of 16 notes, and 2 mono "solo" modes. A lot of parameters can be modulated with MIDI controllers, to give the best live expressivity. It has a full embedded file-based preset management which reacts to MIDI program change messages. A Demo track can be heard here : https://soundcloud.com/arthelion/moloss-ii-demo-2023 Old MOLOSS I Demos : http://soundcloud.com/arthelion/moloss-i-demo https://soundcloud.com/arthelion/03-creepy-nightmare -

AGS - Advanced Gtk+ Sequencer
audio sequencer
Advanced GTK+ Sequencer is intended to use for music composition. It features a piano roll, as well a synth, matrix editor, drum machine, soundfont2 player, mixer and an output panel. It's designed to be highly configurable, you may add effects to its effect chain, add or remove audio channels/pads. You may set up a fully functional network of engines, therefore exists a link editor for linking audio lines. In conjunction with ags you need a realtime kernel and alsa support. `ags` uses conditional locks to keep several threads in sync that's why you need at least a preemptible kernel. -

chdh - egregore source
Source code adaptation of the egregore performance by chdh
This is an adaptation of the software used by chdh for the performance egregore in 2011-2013. It is based on five different audiovisual instruments made of chaotic and physical modeling algorithms that you can directly control. They have been remotely controlled live by chdh the 27th may 2015. You can play, adapt, and use this audiovisual instrument for yourself. It is based on physical modeling and chaotic algorithms entirely build in the Pure Data software. -

Windows console tone generator
Windows console tone generator,
Was unable to find simple program to generate sound using a batch file or windows console. I needed this and thought at first that everyone and their brother had already written a simple program to output a sound using the default sound device on a windows 32 or 64 computer by typing tone plus frequency and duration (in milliseconds) Tone 1000 2000 (1khz at 2 seconds) great for server farms. This is a spin-off of a project of controlling a inteliport III. I got lazy and will just use mp3 files to do the job. This program is written using windows API calls and works on 32/64 bit systems (apple macbook pro using win 7 32 bit pro and also a 64 bit hp computer running win 7 ultimate 64. I did find out this had problems running on a 32 bit eee pc 901 running winXp with a realtek HD audio output…I concluded the problem might be with the sound driver. Usage: tone 440 1000 generates 440hz tone for 1 second this was compiled using Code blocks with gcc. Source code included -

Etheric Synthesizer
Theremin synthesizer for Android devices
Etheric Synthesizer (EtherSynth) is a theremin-like synthesizer application for Android platform, which allow you to play otherworldly melody by swiping finger on the screen. Though It does not closely imitate a real theremin as Etheric Synthesizer uses only one finger to play. It currently supports monophonic note playing with configurable waveform, frequency scale, control area, and control orientation. Basic recording function is also included (WAVE format). Etheric Synthesizer works on Android version 2.0 and above. -

Thérémine
Thérémine generates high quality audio from an USB Arduino Theremin
Thérémine is an audio program which reads realtime pitch and volume data from an USB Arduino Theremin, and generates high quality audio signal emulating a realistic instrument. It was originally designed to work with an Open.Theremin.UNO shield (see http://www.gaudi.ch/OpenTheremin), although it should work with other Arduino devices as long as you provide an appropriate program. Thérémine can play a variety of different tones. It comes with another program, Loop bank manager, whose purpose is to extract stationnary, looping samples from recorded wave files. It allows importing new instrumental tones into Thérémine, as long as the source recording contains reasonable data. Two demo sample banks are provided with Thérémine featuring violin and voice tones. Both were made using Loop bank manager. -

Audivolv
Artificial intelligence evolves musical instruments played with mouse
Artificial Intelligence (AI) evolves musical instruments you play with the mouse from small blocks of Java code that operate on numbers, each block designed to keep all numbers in range -1 to 1 if they started in that range, and combinations of these evolved codes running 44100 times per second for high quality 44.1 khz audio. You can also write the Java code into its window. Uses Javassist internal compiler on the new Java code assembled by renaming variables to overlap eachother and reordering, copying, and removing blocks of code. Listen to the recorded music in files section of sourceforge or try it for yourself. This branched into my other projects: GigaLineCompile, JSelfModify, JSoundCard, and Human AI Net as I got more into the AI and systems side of things and explored vision research as a better user interface to network minds together through the Internet. Someday I will bring it all together in a shared space on the Internet. -
