- Select a 48 kHz mono or stereo WAV lasting at least 0.4 seconds.
- Run the measurement and read integrated loudness alongside the gating and channel details.
- Save the report and check true peak separately before choosing any gain change.

Understand what gating leaves out
Integrated loudness uses ITU-R BS.1770-5 K-weighting and absolute/relative gating. Quiet sections below the gates do not contribute in the same way as an ordinary full-file average. Read the declared standard, block counts and gates when comparing reports from different meters.
True peak and sample peak answer different questions
Interpolation estimates peaks between stored samples. That estimate can exceed the largest sample value. The report does not change your WAV or establish compliance with a broadcaster or platform requirement; compare its stated scope with the measurement required for delivery.
