Sigma Audio Offers Bute Loudness Compliance Software Suite

Sigma Audio has developed a suite of products that automate and completely streamline the processes involving in ensuring content compliance for audio program (and advertising) loudness. Called Bute, the software suite includes an analyzer and a normalizer that are both designed to deal with the increasingly fast-paced world of audio production and post.

The Sigma Audio Bute Loudness Normalizer automates the task of loudness compliance using special algorithms that monitor signals and ensure compliance no matter how compressed or dynamic the material is. Bute also includes the latest Netflix delivery spec and support for Atmos 7.1.2.

The user interface offers a metering graph before and after a file is normalized, with analysis of short-term and momentary loudness, RMS, true peak and loudness range. A built-in true peak brick wall limiter has been optimized to catch any remaining overshoots.

The detailed insight offered by the metering graph shows the extent of true peak limiting and alerts a user to the areas of their audio that are non-compliant. Due to its intelligent algorithms, the Bute Loudness Normalizer can adjust for a range of anomalies, including with the true peak brick wall limiter engaged.

A wide selection of the latest loudness standards are built-in to make workflow even smoother, including the latest revisions of ITU BSS.1770, EBU R128, ATS/C 85, OP-59, ARIB TR-B32, Atmos 7.1.2, YouTube, Apple Check, Spotify, Sony Gaming ASWG, PRSS, AES Streaming recommendation, TIDAL, Hulu, Netflix (including the latest revision), and Pandora. Users can also create and save their own specifications and house rules.

The Bute Loudness Normalizer and Analyzer are now available in two versions: for Surround and Stereo content. Sigma Audio's loudness software is also available as a bundle that includes the analyzer software as well.
