> Digital Signal Processing Library and Audio Toolbox for the Modern Synthesist.

## Attention

This library is still under development!  
Read the [docs](/docs) and check out the [examples](/examples).

Currently looking for contributors / enthusiasts, if you have an idea, found a bug or have an amazing new feature you want to add, feel free to clone, edit and open a Pull Request.

## Building

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

mkdir build
cd build
cmake ..
make install
```

## Usage

```cpp
// 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;
}
```

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