• Audio plug-ins (VST, AU, JUCE)
• Mobile apps (iOS, Android)
• VCV Rack modules

✨ Features

• Control Signal Generators AD and ADSR Envelopes, Phasor
• Drum Synthesis Analog/Synth Bass/Snare Drum Models, HiHat
• Dynamics Processors Crossfade, Limiter
• Effects Processors: Phaser, Wavefolder, Decimate, Overdrive
• Filters: One pole Lowpass and Highpass, FIR, SOAP
• Noise Generators Clocked Noise, Dust, Fractal Noise, Particle Noise, Whitenoise
• Physical Modeling Synthesis Karplus Strong, Resonators, Modal Synthesis
• Sampling Engines Granular Player
• Synthesis Methods: Subtractive, Physical Modeling, FM
• Utilities: Math Functions, Signal Conditioning, Aleatoric Generators, Looper, DCBlocker

🚀 Getting Started

• Get the source: git clone https://github.com/electro-smith/DaisySP
• Navigate to the DaisySP repo: cd DaisySP
• Build the library: make
• Make some noise with the example programs!

👨‍💻 Code Example

#include "daisysp.h"

static daisysp::OnePole flt;
static daisysp::Oscillator osc, lfo;
float saw, freq, output;

for(size_t i = 0; i < size; i++)
{
  freq = lfo.Process();
  saw = osc.Process();

  flt.SetFrequency(freq);
  output = flt.Process(saw);

  out[i] = output;
}
