Bit Crusher
Semantic type: BitCrusher · Category: lo-fi
Reduces amplitude resolution and sample-rate fidelity for digital quantization effects.
This type can intentionally generate output from zero input at an active setting. See Processing model.

Bit Crusher
An effect that recreates the sound of vintage digital devices like old gaming consoles and early samplers. Perfect for adding retro character or creating a lo-fi atmosphere.
Sound Character Guide
- Retro Gaming Style:
- Creates classic 8-bit console sounds
- Perfect for video game music nostalgia
- Adds pixelated texture to the sound
- Lo-Fi Hip Hop Style:
- Creates that relaxing, study-beats sound
- Warm, gentle digital degradation
- Perfect for background listening
- Creative Effects:
- Create unique glitch-style sounds
- Transform modern music into retro versions
- Add digital character to any music
Parameters
- Bit Depth - Controls how “digital” the sound becomes (4 to 24 bits)
- 4-6 bits: Extreme retro gaming sound
- 8 bits: Classic vintage digital
- 12-16 bits: Subtle lo-fi character
- Higher values: Very gentle effect
- TPDF Dither - Makes the effect sound smoother
- On: Gentler, more musical sound
- Off: Raw, more aggressive effect
- ZOH Frequency - Affects the overall clarity (4000Hz to 96000Hz)
- Lower values: More retro, less clear
- Higher values: Clearer, more subtle effect
- Bit Error - Adds vintage hardware character (0.00% to 10.00%)
- 0%: No DAC bit-weight mismatch; Random Seed has no audible effect
- 0.1-1%: Subtle digital DAC coloration
- 1-3%: Classic hardware imperfections
- 3-10%: Creative lo-fi character
- Random Seed - Controls the unique character of imperfections (0 to 1000)
- Changes the fixed imperfection pattern used by Bit Error
- Audible only when Bit Error is above 0%
- Same value always recreates the same imperfection pattern
