Ian Welkins
Builder of small, honest web calculators — and the person who maintains every tool on this site.
A short bio
I am Ian Welkins. I live and work in Houston, Texas, and I spend most of my working time building small calculators for the web. Not platforms, not apps with accounts and dashboards — just single-purpose tools that answer one question well and show their working.
Music is my hobby rather than my trade. I mix at home, at hobbyist level, on headphones more often than I would like to admit. That hobby is the reason this particular site exists: my reverb settings used to live as a hand-copied table in a mixing notebook, correct at one tempo and wrong at every other. Turning that table into a set of live tools was a weekend project that turned out to be useful to more people than just me.
My working rule across all my sites is the same: publish the method with the answer. If a page gives you a number, the formula, the sources and a worked example should be one click away, so you never have to take the number on faith.
When I am not building or mixing, I am usually reading about both — acoustics papers I only half understand, and mixing writing from people with far better ears and far longer careers than mine.
What I maintain here
I maintain everything on Reverb Calculator personally: the combined reverb and delay calculator on the home page, the focused tools such as the Vocal Reverb Calculator and the Snare Reverb Calculator, the printable BPM to MS Chart, and the RT60 Calculator for room acoustics. I also maintain the Methodology page, which is where the formulas and worked examples live.
Maintenance here means checking numbers, not just keeping the lights on. When a source changes or a reader reports a suspect value, I re-derive the affected figures by hand and fix the page if the report is right.
Elsewhere
I keep four public profiles, and they are the same ones linked from the footer of every page here. My code and project work are on GitHub. Occasional writing about building these tools is on Dev.to. A short standing profile is on About.me, and my avatar and public identity record are on Gravatar.
Those four profiles are the canonical list. If you find an account in my name somewhere else, it is either new and not yet linked here, or it is not mine.
