Bit-crusher is a human-made audio effect that reduces the bit depth and sample rate of a digital audio signal to produce quantization noise, aliasing, and lo-fi timbral distortion. Parameters: (1) bit depth reduction — target resolution from 24/16 down to 1-8 bits; (2) sample rate reduction — downsampling factor applied to the signal; (3) mix — wet/dry blend of crushed and original signal; (4) decimation filter — optional reconstruction smoothing. Mechanism of persistence: it persists as DSP algorithms implemented in audio plugins, hardware effects units, and software synthesizers, documented in signal-processing literature and taught as a standard lo-fi technique.

Definition
Why it is in scope
Bit-crusher is a human-made audio effect that degrades digital audio by reducing bit depth and sample rate, built to persist as a studio effect and plugin.

Bit-crusher is an audio effect technique built for the sake of audio engineering: it reduces bit depth and sample rate to produce lo-fi texture, used in mixing and sound design. Servant points at master per Law 8d.

Bit-crusher operates by reducing bit depth — which IS quantization (mapping continuous amplitude values to a finite set of discrete levels). Remove quantization and bit-crushing ceases to operate: its core mechanism is quantization noise generation. Pinned sense: quantization as the amplitude discretization process applied to audio signals.
- distortionINSTANCE_OF →
Bit-crusher is a specific kind of distortion effect: it reduces bit depth and sample rate to produce quantization noise and aliasing, which are forms of harmonic distortion. A competent audio engineer would classify bit-crusher as a type of distortion effect, alongside overdrive, fuzz, and clipper. Nearest-kind INSTANCE_OF.
