A Bit Crusher is an audio effect that produces digital distortion by reducing the quality or bandwidth of digital audio data. The resulting quantization noise may produce a "warmer" sound impression, or a harsh one, depending on the amount of reduction applied to your audio.
If you haven't yet already, check out our Effects Overview for details on adding / removing effects, as well as a breakdown of the various stages you can insert effects into your Composition.
The Bit Crusher comes with an array of starter presets to choose from:
- Speak and Spell
- TMSxxxx LPC Chip
- GBA Chip
- CTxxxx Chip
- ASC Chip
To choose a preset click the "Select Preset" dropdown selector:

You can also manually adjust your settings by clicking on the Show Details button to the right of the preset selector:
Below is a brief overview of each of these settings:
- Bit Depth - Determines the total number of bits (computer memory) used when processing the audio. Reducing this value will cause audible distortion in the resulting signal and may also affect volume of lower frequencies.
- Frequency - Determines the sampling rate of the effect. Reducing the frequency will degrade the accuracy of the digital signal typically causing high-frequency "aliasing" or artifacts in the result.
