AudioDenoise ver. 1.0.45, Copyright © 2015 CrumplePop

AudioDenoise is an audio unit plugin, not a standalone application, so it is updated through the host application's plugin management system rather than as an independent download. To update AudioDenoise to a native Apple Silicon build (if available), you must first ensure your host DAW or audio application is running the latest native version — Logic Pro, GarageBand, Final Cut Pro and most professional DAWs ship native builds on M-series Macs. After updating the host, check whether Crumplepop has released a native AU version of AudioDenoise through their vendor installer or website. If a native build is not yet available from Crumplepop, contact the vendor directly to ask about Apple Silicon support before macOS 28 ships in September 2028, since the Intel-only plugin will stop working on that release. You can also explore whether your DAW offers built-in noise reduction as a fallback, or consider native alternatives like iZotope RX Elements (which has native plugins) or the noise-gate tools built into professional DAWs.
