@audio/denoise vs Vinyl Restoration Suite

@audio/denoise is a free web tool for cleaning recordings and listening to or saving the result. It handles targets including steady background noise, mains hum, clicks, pops, vinyl crackle, clipping, wind rumble, plosives, sibilance, room reverb, and noise between phrases. The page describes thirteen open-source restoration methods and a classifier. Automatic mode measures properties of a recording, selects a specialized method, and displays its plan; users can instead choose methods such as dehum, declick, declip, and gate. Audio is processed in the browser, and the page says it is not uploaded or sent off the device. The approach uses classical signal processing rather than AI noise removal. For music, the page identifies hum, clicks, crackle, and clipping as treatable, while advising light use of broadband denoising and comparison with the original. Machine-learning models may perform better on heavy speech-over-noise. The associated npm package processes mono Float32Array audio. Automatic mode does not choose dereverb, which must be selected explicitly.

Vinyl Restoration Suite is a free audio restoration plugin and standalone application for Windows, macOS, and Linux. It detects and repairs clicks and pops using crossfade and spline interpolation, and reduces noise with real-time FFT processing that can capture a noise profile. Its AI denoiser is based on RNNoise and supports DirectML and NPU acceleration. A 10-band graphic equalizer covers 31 Hz to 16 kHz, while separate filters address subsonic rumble from 5–150 Hz and AC power line hum from 40–80 Hz. The app can record audio and split tracks automatically at silence. Real-time waveform and spectral views help monitor audio, and Difference Mode plays the noise and clicks being removed. Use it as a VST3 plugin in a DAW or independently as a standalone app. Pre-built binaries are listed for all three desktop systems; the macOS DMG is described as universal for Intel and ARM. It is available under the MIT license at free.
