Loudness Range (LRA) Analyzer

Measure LRA per EBU Tech 3342 and interpret it: is your mix over-compressed, comfortable, or too dynamic for the target platform?

LRA measures how much your programme's loudness varies(95th − 10th percentile of gated short-term loudness, per EBU Tech 3342). It answers a different question than LUFS: not "how loud?" but "how dynamic?".
