# submono

A Web Audio subtractive, monophonic synthesizer. Looking for polyphony? Check out [subpoly](https://github.com/okaybenji/subpoly/)!

### Create a synth.

```

var audioCtx = new AudioContext();

var synth = new Monosynth(audioCtx);

```

### Play a note.

`synth.start();`

### Stop playing.

`synth.stop();`

### Use methods to access pitch and waveform...

```

synth.pitch(440);              // in hertz

console.log(synth.waveform()); // 'sawtooth' (or sine, triangle, square)

```

### ...get or set any other properties directly.

```

synth.maxGain = 0.5; // out of 1

synth.attack = 1.0;  // in seconds

```

### Configure any or all the properties on initialization.

```

var config = {

  waveform: 'sawtooth', // or sine, triangle, square

  pitch: 440,           // in hertz

  maxGain: 0.5,         // out of 1

  attack: 0.1,          // in seconds

  decay: 0.0,           // in seconds

  sustain: 1.0,         // out of 1

  release: 0.8,         // in seconds

  cutoff: {

    maxFrequency: 7500, // in hertz

    attack: 0.1,        // in seconds

    decay: 2.5,         // in seconds

    sustain: 0.2        // 0-5; maxFrequency multiplied by this

  }

};

var synth = new Monosynth(audioCtx, config);

```
