Audio restoration is the algorithmic repair of degraded audio signals. The technique analyzes corrupted audio (noisy, clipped, bandwidth-limited, or physically damaged) and applies signal processing operations — spectral subtraction, de-essing, de-clicking, equalization, and noise gating — to recover the original signal or improve perceptual quality. The persistence mechanism is implementation as executable DSP routines in audio editing and archival software.

Definition
Why it is in scope
A human-made signal processing technique that recovers, enhances, or repairs degraded audio signals through algorithmic processing. Includes restoration from noise, clipping, bandwidth limitation, and physical damage to media. Built to persist as implemented procedures in digital signal processing and archival audio pipelines.

audio-restoration IS a specific kind of signal processing: it applies mathematical techniques to signals (audio) to remove degradation, noise, and artifacts. A competent speaker would call it 'a kind of signal processing.' This is the nearest kind — no more specific signal-processing subcategory exists.
- cmsql7gfa001gnf0j5qt1ju3cDERIVED_FROM →
Noise reduction techniques predate audio restoration as a practice. Audio restoration emerged from and built upon noise reduction methods — the historical sequence is clear: noise reduction came first and fed into the broader practice of audio restoration.

Audio restoration is a signal processing operation — it uses filtering, spectral analysis, noise reduction, and other signal processing techniques to repair degraded audio. Remove signal processing and audio restoration has no methods to operate. Constitutive dependency.

Spectral-subtraction is designed for audio-restoration: its purpose is to remove noise from audio signals to restore quality. It is maintained as a technique specifically to further audio restoration's operation.
