Loudness Report Comparator
Compare two mono/stereo files using B-minus-A integrated loudness, loudness-range evidence and inter-sample peak-estimate differences without declaring a quality winner.
Use this for before/after processing checks, alternate masters, or two versions of the same programme. A difference is descriptive, not a quality score.
Ready.
How to interpret the result
Build 123 extends the mono/stereo BS.1770-style analytical foundation from Builds 121–122. Values are evidence for comparison and planning. They are not a certified delivery-compliance verdict.
Important limitations
MesraTools does not label one file as better merely because it is louder, quieter, wider in loudness range, or has a different peak. Platform and broadcaster requirements can change; verify the current official specification for actual delivery.
