🚀 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;
}
