Building

git clone https://github.com/everdrone/libsnd.git
cd libsnd

mkdir build
cd build
cmake ..
make install

Usage

// main.cc
#include <iostream>
#include <snd.h>

#define SAMPLE_RATE 44100

int main(int argc, char **argv) {
  snd::Sine<float> s(SAMPLE_RATE);
  s.setFrequency(440);

  for (int i = 0; i < 512; i++) {
    std::cout << s.tick() << std::endl;
  }

  return 0;
}

g++ main.cc -o a.out -lsnd
