OTT is a free dynamic range compressor Audio Unit (AU) plugin from Xfer Records, designed for mixing and mastering. It operates across three frequency bands (low, mid, high) with independent gain and time controls on each, making it a popular tool for controlling dynamics, saturation and tone-shaping in music production. OTT ships as an AU audio plugin that runs inside a DAW's host process rather than as a standalone application. A native Apple Silicon build of OTT has been confirmed running on Macs in the Rosetta Check community.
AI Recommendation
1 suggestionXfer Records ships OTT with native Apple Silicon support, and you can get the latest native AU version directly from their freeware page. Visit xferrecords.com/freeware, download the current OTT installer for macOS, and run it — the installer will place the native Universal Binary AU component in your system's Audio Plug-Ins folder. After installation, restart your DAW and OTT will load natively without Rosetta 2. If you have an older Intel-only version of OTT.component still installed (particularly version 1.26 or earlier), the Xfer support forum recommends removing the old component before installing the new one: open Finder, press Command-Shift-G, navigate to /Library/Audio/Plug-Ins/Components and ~/Library/Audio/Plug-Ins/Components, and delete any OTT.component files you find. You can verify which version is running by clicking the text label below the OTT logo inside the plugin interface.
