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.
