Our mission
Making good sound accessible to everyone
Clean, free audio tools were missing: no sign-ups, no wall of ads and no inflated results. So we built them ourselves.
AcusticaX is a sound-technology project for enthusiasts and professionals alike. We build apps that measure, test and calculate right on your device, and pair them with gear reviews and technical guides written to actually be understood. Our goal is that you leave knowing something you didn’t, with a tool that genuinely helps.
How we work
Four principles we don’t compromise on
They’re why you can trust what we measure, review and publish.
We measure, we don’t guess
Every tool is built on real physics —FFT, RT60, weightings, matched filter— and every figure is verified before we publish it. If something is a rough estimate, we say so.
Honesty by default
Hearing-safety notices, “indicative, not lab-grade” and clear limitations. We’d rather give you a figure with caveats than a promise that doesn’t hold up.
Everything in your browser
Sound is processed on your own device with Web Audio. We never upload your files or store your audio: your privacy isn’t the price of admission.
No sign-ups, no fluff
Free and account-free. Deliberately light and fast, with no unnecessary plugins and no wall of ads between you and the tool.
What you’ll find here
Three ways to get more out of your sound
Tools to measure, reviews to decide well and guides to understand the why.
Tools
17 audio apps: hearing test, ABX, sound-level meter, generator, RTA, room acoustics, turntable, mic measurement and more.
Reviews
Headphone, speaker and gear reviews with technical judgment and no hype: what it does well, what it doesn’t and who it’s for.
Technical guides
Acoustics and sound fundamentals explained step by step, so you understand the why and not just the how.
