Audio-dithering is a human-made signal processing technique that adds low-level noise to a digital audio signal before quantization or bit-depth reduction to decorrelate quantization error and prevent distortion artifacts. Parameters: dither noise shape (triangular, rectangular, Gaussian), amplitude relative to least significant bit, noise bandwidth, and application point in the processing chain. Persistence mechanism: documented in digital audio engineering literature, implemented in DAW plugins and audio hardware, and taught in audio engineering curricula; the technique persists through code libraries, plugin implementations, and standardized digital audio workflows.

Relations from this entry

Audio-dithering IS a specific audio processing technique: it decorrelates quantization error during bit-depth reduction in audio signal chains. The audio-processing definition explicitly lists 'restoration' as a processing type, and dithering is a restoration technique applied within audio processing chains. Nearest kind per Law 11e: audio-processing (not signal-processing, which audio-processing is itself an instance of).

Dithering is designed to produce white (spectrally flat) quantization noise — spreading error energy evenly across the frequency spectrum rather than concentrating it as tonal distortion. The purpose of dithering is to achieve spectral flatness of the error signal.

Audio dithering is designed and maintained for the sake of improving quantization quality by decorrelating quantization error and preventing distortion artifacts. The servant points at the master per Law 8d.

Audio dithering is built and maintained for the sake of audio processing: it decorrelates quantization error and prevents distortion artifacts during bit-depth reduction in audio signal chains, enabling cleaner processing in recording and mastering. For whose sake? Audio processing benefits from dithering's error reduction.

Audio dithering is applied before quantization or bit-depth reduction to decorrelate quantization error. Remove quantization and dithering has no operation to improve.
