@audio/denoise vs LANDR ReHance

@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.

LANDR ReHance uses AI to analyze audio and remove unwanted artifacts such as background noise, clicks, pops, plosives, bleed and reverb. It is available in the LANDR Library online or as a plugin for a DAW, and LANDR says enhancement is unlimited in either format. Three intensity levels provide a choice of processing strength. The tool is described for podcasts, voice memos, field and home studio recordings, video audio and live recordings with instrument bleed. The plugin supports VST3, AU and AAX formats and works with major DAWs that support them. It requires macOS 10.15 or later or 64-bit Windows 10 or later, plus an Intel Core i5, AMD Ryzen 5 or Apple Silicon equivalent and 4 GB RAM. LANDR says the audio technology is powered by Insoundz. ReHance is not available in the LANDR App, though LANDR says it can be used in mobile browsers. A LANDR Studio subscription is required; the listed annual-plan price for a subscription including ReHance is $11.99 a month. A 3-day trial is offered for any Studio tier, and the subscription starts automatically unless cancelled before the trial ends.
