Bitcrusher Node

Experimental as of 0.5.0

The Bitcrusher Node adds controlled amounts of distortion, audio fidelity reduction, and quantization noise to an audio signal, to produce an output intentionally reminiscent of lofi music.

Audio Input

An audio signal to bitcrush.

While the Bitcrusher Node is primarily for audio, a control signal can also be used here, in which case the Node will apply the same effects.



Wet/dry signal ratio. That is, the higher this setting is, the more the bitcrushed signal is present in the output (and the less the original signal is present in the output).

Bit Depth

Simulates the maximum audio bit-depth in the audio signal, as if it was represented with fixed precision.

Simply put, a lower bit depth makes the audio signal sound more noisy. However, this slightly different from just adding noise with a White Noise Node.

Note: currently, this effect is less emphasized with louder audio signals.


The amount of downsampling to apply, as a percentage. As you increase this effect, it adds increasing amounts of quantization noise to the output.

0% means no sample reduction, while 50% means reducing the sample rate by half. While 100% means a complete sample rate reduction, it essentially makes the output silent, because it’ll hold the last sample indefinitely.


Audio Output

The bitcrushed audio signal (or control signal, if that’s what you connected to the input).

Technical Details


The downsampling setting does not actually result in a reduced sample rate in the output signal. This is because all audio connections in AudioNodes use the same sample rate. Instead, it simulates a sample rate reduction using a sample-and-hold algorithm.
