01Overview

LCAST Stereo is built for producers and engineers who need to measure loudness and catch inter-sample peaks before delivery. Its main display is a loudness history plot that records a timeline of your programme, showing integrated, short-term and momentary loudness along with a custom variance measurement. Presets cover the most common broadcast standards, so you can switch targets without digging through settings. The plugin runs on Windows and macOS in several formats, which makes it a practical addition to a mastering or post-production session.

Loudness History and Standards Presets

The history plot works like a personal video recorder for your audio, storing up to 24 hours of loudness history. Each measurement can be toggled on or off, so you can focus on the readings that matter for a given job. The plot makes it easier to spot loud passages, quiet dialogue or other sections that need adjustment.

For standards, LCAST Stereo includes presets for ATSC A/85 (CALM Act), ITU BS.1770 and EBU R128. Loudness gating and custom color regions are also available, and the plugin handles mono and stereo signals.

True-Peak Metering and Offline Measurement

The true-peak meters detect inter-sample peaks that other meters can miss. According to MeterPlugs, the plugin does this by oversampling the signal internally and interpolating between samples, then warns you of potential clipping with overload indicators.

If your DAW supports offline processing, LCAST Stereo can calculate integrated loudness, loudness range and other measurements faster than realtime. This suits long-form content such as albums, films and TV shows.
