Report an Error

What counts as an error

A wrong number, a wrong formula, a broken or misbehaving tool, and a plain typo all count. So does a value that disagrees with another page on this site: every tool here uses the same calculation library, so two pages showing different answers for the same inputs means at least one of them needs attention.

A preset label that seems misleading counts too, and so does guidance on a tool page that contradicts the numbers the tool itself produces. Wording errors can send a mix in the wrong direction just as surely as arithmetic errors can, so they are treated with the same seriousness.

What to include

Three details make a report checkable in minutes: the page where you saw the problem, your BPM and settings (or your room details, for the RT60 tool), and the value you expected to see, with a line on how you calculated it if you can. Screenshots help for layout or display problems, but the three details above matter most.

If you can, copy the exact value the tool showed rather than a rounded version of it. The difference between, say, a decay of 984.38 ms and a rounded 984 ms can be the clue that pinpoints where a display or rounding step went wrong.

How to send it

Email ianwelkins@gmail.com with the subject “Reverb Calculator — error report”. The link pre-fills that subject; just add your page, settings and expected value in the body of the message.

What happens next

Your report is checked against the formulas on the Methodology page — the same derivations the tools are built from. If the site is wrong, it gets fixed and you get a reply saying what changed. If the site is right, the reply walks through the calculation so you can see where the two results diverged. Either way, you hear back.

Please allow a few days for that reply when the check involves re-deriving a full table by hand. A short report with the details above is still the fastest route to a fix — far faster than a long description without the settings.
