BUTE Loudness Suite 2 (Surround)

BUTE Loudness Suite 2 (Surround) is a metering and limiting plugin designed for producers working within loudness specifications across stereo and immersive formats up to Atmos 7.1.2. The plugin combines real-time loudness analysis with transparent limiting, allowing engineers to mix and master while maintaining compliance with broadcast, streaming, and internal standards without introducing audible artifacts.

The core strength lies in its synchronised workflow. The smart auto re-metering feature provides instantaneous feedback on how mix adjustments affect overall loudness, eliminating the tedious process of manual re-measurement after each change. The history overview function handles extended content efficiently, displaying up to 10 hours of metering data in an interactive display with precise navigation and clear flagging of True Peak violations.

Technically, BUTE reads in LUFS and True Peak measurements, with toggleable absolute and relative scaling modes, ensuring compatibility with virtually any loudness standard. The limiting engine operates transparently enough for mastering use while remaining effective enough for mix protection. A collection of industry-standard presets provides starting points across genres and delivery formats.

The plugin works across VST, AU, and AAX including Audio Suite, making integration straightforward in most modern DAWs. Its resizable interface and compact read-out mode preserve screen real estate without sacrificing access to metering and limiting controls.

BUTE suits broadcasters, streaming engineers, post-production professionals, and game audio specialists where loudness compliance is non-negotiable. It represents a practical, competent solution for loudness-critical work rather than a revolutionary approach, but its straightforward implementation and robust feature set make it a reliable choice for environments where specification adherence matters.
