Simple and efficient audio synthesis in C .
Prefer coding to patching? Love clean syntax? Care about performance? That's why Tonality was made.
// Tonality is a collection of signal generators and processors
TriangleWave tone1 = TriangleWave();
SineWave tone2 = SineWave();
SineWave vibrato = SineWave().freq(10);
SineWave tremelo = SineWave().freq(1);
// that you can combine using intuitive operators
Generator combinedSignal = (tone1 tone2) * tremelo;
// and plug in to one another
float baseFreq = 200;
tone1.freq(baseFreq vibrato * 10);
tone2.freq(baseFreq * 2 vibrato * 20);
With Tonality you can create an awesome synthesizer with just a couple lines of code.
ControlXYSpeed speed = ControlXYSpeed().x(addParameter("x")).y(addParameter("y"));
outputGen = RectWave().freq(100).pwm( 0.1 (SineWave().freq(0.1) 1) * 0.1) * SineWave().freq(1) >> LPF12().cutoff(100 600 * speed);
This code creates a rectangle wave oscillator, modulates the timbre of that oscillator by a sine wave, adds some slow tremelo, and sends it through a filter. On top of all that, it maps mouse speed to the cutoff frequency.

Tonality comes with several example projects, found in the "examples" directory. I plan to add more demo projects for Windows and Linux in the future.
- Several example synth patches in
Demo Synths
- Standalone example using RTAudio for building a non-interactive synth patch that runs from the command line
- iOS example for making synths on your iPhone/iPad.
