@audio/denoise vs Wave Corrector

@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.

Wave Corrector records analogue music, reduces noise, and converts recordings to digital audio. Its processing can remove surface sounds such as clicks, ticks, and plops, with a separate hiss-removal option for tape. Users can record directly or set unattended recordings, including radio broadcasts. The software can split recordings into numbered tracks automatically, then lets users adjust boundaries and add fades. The Professional Edition adds filters, a graphic equaliser, volume normalisation, channel balance, and Cut and Splice tools. Version 3.9 has built-in MP3 encoding and uses Discogs track durations to guide and validate track detection; it can obtain durations from MusicBrainz if Discogs has none. Noise reduction, hum removal, and batch processing are also listed. Wave Corrector runs on Linux and Windows and is intended for home music lovers and professional archivists. The personal-use Professional Edition costs nothing, with no registration required. The download page offers 32-bit and 64-bit Professional Edition 3.9 installers; the Standard Edition is no longer available.
