What Signum Audio BUTE Loudness Suite 2 is

Signum Audio BUTE Loudness Suite 2 is an audio toolkit for loudness measurement, true-peak limiting, and normalization in mixing, mastering, post-production, broadcasting, and gaming audio. The bundle includes BUTE Loudness Analyser 2 with an integrated True Peak Limiter, BUTE Limiter 2, and the BUTE Loudness Normaliser application. The True Peak Brickwall Limiter is designed to catch true-peak overshoots, while the product page describes limiting and normalizing as faster than real time. The analyser offers a warning system, history overview and graph, DAW synchronization for automatic re-metering, and multiple meter ballistics. Built-in presets cover standards and targets including ITU-R BS.1770, EBU R128, ATSC A/85, Sony ASWG, Spotify, YouTube, and Pandora. Supported formats are VST, VST3, AU, AAX, and AudioSuite, including AudioSuite for Pro Tools. The Stereo version handles stereo; Surround adds multichannel formats such as 5.1, 7.1, and up to 10-channel Atmos. Stereo costs £199, paid once; Surround costs £249, paid once. Both offer free 14-day trials. The software supports macOS and Windows.
