Built in Montreal, QC by Sehmus — musician, creator, memoliro/jsm-loudness.com. We tested same file HAYDI DÖN.WAV across lufs.org -14.05 -3.08, wutools -14.0 -3.1 PASS, SoundBoost -14.0 and found free tools showing -17.5 — 3.4 dB off because they use RMS not ITU-R BS.1770-4. We implemented exact EBU R128 with K-weighting two biquads, 400ms blocks 75% overlap, -70 abs -10 rel gate, true peak 4x. 100% browser, no upload, private. Verified.
