Findings and recommendations

Inter-sample peaks at 0.13 dBTP (50 overs) warning

Lossy encodes (AAC/Ogg) can overshoot on decode. If the loudness is intentional this is a trade-off, not a defect.

Set the final limiter true-peak ceiling between -0.3 and -1 dBTP, or accept the overs for a louder master.

Loud sections are in the benchmark range good

-5.9 LUFS vs benchmark -6.4 ± 1.4.

Loudness per ITU-R BS.1770-4 / EBU R128 (K-weighting, gated), true peak by 4x oversampling. "Loudest 20%" = 3 s windows at or above the 80th percentile of short-term loudness. Spectrum bands are relative to total energy so they compare shape, not level. Hover a term for its definition. How to read this report.
