bx_limiter
bx_limiter True Peak is a VST3 audio plugin from Brainworx (distributed via Plugin Alliance) designed for professional mastering and loudness-compliant mixing. It is a true peak limiter that uses selective oversampling and advanced look-ahead algorithms to control intersample peaks while maintaining transparent audio quality. The plugin includes integrated loudness metering, stereo correlation monitoring, XL saturation for added character, and tone-shaping filters. It is available in multiple formats including AAX Native, AU, VST2, and VST3, and is included in Plugin Alliance's CORE and PRO subscriptions.
AI Recommendation
1 suggestionbx_limiter True Peak is a plugin component, not a standalone application, and is updated through Plugin Alliance's Installation Manager rather than independently. According to the changelog, the plugin received native Apple Silicon (AAX) support in version 1.2.0 (August 2023), and the latest version (1.3.0, February 2025) is confirmed to include native Apple Silicon compatibility for VST3 format as well. To update to the native build, use the Plugin Alliance Installation Manager (the official update channel for all Plugin Alliance products including Brainworx plugins): download it from Plugin Alliance's website, launch it, select bx_limiter True Peak, and choose the VST3 format for your system. The Installation Manager will automatically serve the native Apple Silicon build on M-series Macs. Your host DAW (Pro Tools, Logic Pro, Ableton Live, Reaper, etc.) must also be running a native Apple Silicon build for the plugin to launch natively — if your DAW is still Intel-only, the plugin will run under Rosetta 2 even after updating, but the DAW itself is what needs updating first.
