AS-Gate
AS-Gate is an Audio Unit (AU) plugin for macOS that functions as a noise gate for audio processing. It is used within Digital Audio Workstations (DAWs) and audio editing software that support AU plug-ins, such as Logic Pro, GarageBand, Reaper, and other AU-compatible hosts. The plugin allows users to mute or reduce audio signals below a specified threshold, commonly used in recording and mixing to eliminate background noise, low-level hum, and unwanted room ambience. The plugin sits within the host application rather than running as a standalone tool.
AI Recommendation
1 suggestionAS-Gate is an Audio Unit plugin, not a standalone application, so it is not updated separately through the App Store or a generic vendor download. Instead, you must update it through your audio host application's plugin manager or by reinstalling the plugin using the vendor's installer. The specific update channel depends on which DAW you use: Logic Pro users should check the Logic Pro Sound Library for plug-in updates via Apple's built-in update system; Reaper users can use Reaper's built-in plugin refresh; users of other AU hosts should visit As-Gate's official vendor website or contact As-Gate support directly to obtain the latest plugin installer. Given that we have limited current information about As-Gate's native Apple Silicon status, contact the vendor to confirm whether a native arm64 build of the AU plugin is available. This is important because Apple is removing Rosetta 2 in macOS 28 (late 2027), so an Intel-only plugin build will stop working on that release and the vendor may have a newer native-compatible version ready.
