Loudness (BS.1770)
The headline addition: a full integrated-loudness check per the ITU-R BS.1770 standard, running as a sixth check alongside Signal Alignment, Spectral Fidelity, Bit-Exactness, Level Fidelity, and Distortion. See BS.1770 loudness, explained for what it measures and where it has blind spots.
$ wavelens analyze --ref reference.wav --dut device_under_test.wav --out report.html
wrote report.html (loudness: FAIL — integrated -14.2 LUFS vs -18.6 LUFS reference)
Analysis Mode tile
Every report now shows an Analysis Mode tile indicating whether that run’s comparison used time-domain or frequency-domain alignment internally — useful when triaging a Signal Alignment result, since the two modes handle certain kinds of latency differently.
Everything else
- Minor performance improvements to the Spectral Fidelity check on files longer than 10 minutes.
- Fixed a rare false-positive on Distortion for multitone reference material with closely spaced frequencies.
wavsummaryoutput now includes a per-check failure breakdown, not just the overall pass/fail count.
Upgrade notes: existing wavelens-defaults.cfg files don’t need any changes — Loudness runs with sensible defaults out of the box, and --no-loudness is available if you need to skip it for content without a meaningful loudness target.
See it for yourself.
WaveLens compares a reference file against a processed copy and shows you exactly where they diverge — down to the sample — not just whether they still sound the same. One command, one report you can point at.
