About

Bit Crusher

This app digitally degrades audio by reducing bit depth and sample rate. It emulates the sound of vintage samplers and early digital hardware, adding unique lo-fi distortion.

Highlights
  • Bit depth reduction (quantization)
  • Sample rate reduction (decimation)
  • Emulates vintage digital hardware
  • Adds quantization noise
  • Creates aliasing artifacts
Features
Read full description

A digital degradation effect that combines two classic forms of lo-fi distortion: bit depth reduction (quantization) and sample rate reduction (decimation). Together they emulate the character of early digital samplers, 8-bit consoles, and vintage hardware with limited converter resolution. The signal is first quantized to a reduced number of bits, introducing the harsh harmonic distortion known as quantization noise. It is then resampled at a lower effective rate using a sample-and-hold stage, producing aliasing artifacts above the new Nyquist frequency.
