A [Bitcrusher](https://en.wikipedia.org/wiki/Bitcrusher) plugin. It can be used to add distortion to an input.

## IN Knobs

* **GAIN:** adjusts input gain.
* **NOISE:** mixes noise with input signal based on the amplitude of input signal.

## OUT Knobs

* **GAIN:** adjusts output gain.
* **CLIP:** adjusts clip level for output signal (positive increases clip ceiling, negative decreases it).

## Other Knobs

* **FREQ:** adjusts samplerate (without interpolation) for time quantization (can be toggled with the button above the FREQ knob).
* **QUANT:** adjusts quantization resolution for amplitude quantization (can be toggled with the button above the QUANT knob).
* **STEREO:** adjusts stereo difference between Left and Right channels by altering the decimation frequency difference (this can minimally impact phase alignment).
