RX Loudness Control is an audio plugin from iZotope, part of the RX suite of professional audio restoration and mastering tools. It is designed to measure, analyse, and adjust loudness levels in audio files according to broadcast and streaming standards such as LUFS, LKFS, and loudness range. Audio engineers and mastering professionals use it to ensure compliance with loudness specifications for different distribution platforms (YouTube, Spotify, Netflix, broadcast television) and to prevent distortion from excessive normalisation. The plugin operates as an AU, VST, or AAX plugin within digital audio workstations and mastering software.

1 suggestionThe bundle ID and app name indicate this is the RX Loudness Control plugin from iZotope. iZotope has released native Apple Silicon versions of their RX suite — the latest versions of RX include Universal Binary builds that run natively on M-series Macs. To confirm you have the native version and to access any performance improvements, launch your digital audio workstation (Logic Pro, Pro Tools, Ableton Live, or similar) and check the plugin scan results, or visit iZotope's account page to download the latest RX installer. iZotope provides free updates to existing RX license holders, so if your copy is older, you should be able to download a newer build at no extra cost. If you are running an older version under Rosetta, updating will free up CPU and improve responsiveness during loudness analysis and processing.
