loudness-metering

To measure LUFS for streaming, this Skill computes loudness metrics using a K-weighting filter chain and two-stage gating, then compares the results against per-platform target presets to validate compliance.

True-peak measurement detects inter-sample peaks that standard sample peak meters miss. This Skill uses 4× oversampling to measure true-peak values, preventing clipping when audio is decoded by lossy codecs on streaming services.

EBU R128 gating uses a two-stage process: absolute gating removes silence below -70 LUFS, and relative gating measures the remaining audio relative to its own average. This Skill applies both stages to robustly measure integrated LUFS and LRA.

Yes, this Skill supports both real-time and offline loudness analysis. It handles per-platform target configuration and uses a JUCE-based audio–UI bridge for real-time display, allowing continuous monitoring during playback.

Yes, K-weighting is a required component of the ITU-R BS.1770-4 standard. This Skill applies a K-weighting filter chain aligned for 48 kHz playback to accurately compute the LUFS, LRA, and true-peak values specified by the standard.

Process your audio file through this Skill to compute its LUFS, LRA, and true-peak values. The Skill validates compliance by comparing these computed metrics against specific target presets for major streaming platforms.
