DaisySP • A Powerful DSP Library in C++

DaisySP is an open-source DSP (Digital Signal Processing) library that provides a comprehensive collection of modular components for creating audio software across various contexts, facilitating the development of high-quality and customizable audio applications.

• Embedded hardware using the Daisy Audio Platform
• Audio plug-ins (VST, AU, JUCE)
• Mobile apps (iOS, Android)
• VCV Rack modules

• 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

• 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!

#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;
}

Thank you to all of the awesome people who have given their time and effort to this project!

Made with contrib.rocks.

Here are some ways that you can get involved:

• Proof read the documentation and suggest improvements
• Test existing functionality and make issues
• Make new DSP modules. See issues labeled "feature"
• Port existing DSP modules from other open source projects (MIT). See issues labeled "port"
• Fix problems with existing modules. See issues labeled "bug" and/or "polish"
