It wraps scipy and numpy to perform frequency weighting and loudness analysis on audio arrays, supporting both measurement and normalization workflows.\n\nThe package provides a Meter class that analyzes audio at a given sample rate, offering integrated loudness measurement, loudness range calculation per EBU Tech 3342, and peak/loudness normalization functions. It includes multiple filter implementations (BS.1770 standard, DeMan, Fenton/Lee variants, and Dash et al.) and allows customization of block size and custom IIR filters for specialized use cases.","worth_installing":"Yes. The package solves a specific, well-defined problem (ITU-R BS.1770-4 loudness measurement) with low install friction, permissive licensing, and active maintenance. It is suitable for audio production, streaming, and broadcast workflows where loudness standardization is required.
