AS-PreAmp
AS-PreAmp is an audio unit (AU) plugin that emulates vintage preamp circuitry for use in digital audio workstations and music production software on macOS. It is designed for audio engineers, producers, and musicians working in professional or home recording environments who need analog-style preamp warmth and saturation in their digital mixes. The plugin integrates into any AU-compatible host application such as Logic Pro, GarageBand, Ableton Live, Reaper, or other DAWs that support the Audio Unit standard.
AI Recommendation
1 suggestionAS-PreAmp is an audio plugin component, not a standalone application, so it cannot be updated independently. It must be updated through your digital audio workstation's plugin manager or the vendor's installer. To ensure you have a native Apple Silicon build, contact As-Preamp directly to confirm whether they ship a native AU version compatible with your DAW. If the vendor supplies a plugin installer, download and run it to update the plugin. If your DAW has a built-in plugin manager (Logic Pro's Plugin Manager, for example), check there for available updates. Confirm that both the plugin AND your host DAW are running native Apple Silicon builds — even if the plugin is native, it will not work properly in an Intel-only DAW running under Rosetta. Given that Rosetta 2 will be removed in macOS 28 (late 2027), if As-Preamp does not have a native Apple Silicon build available by that date, the plugin will stop working altogether on newer macOS versions.
