Simple, Accurate SPL Measurement On Your iPhone | Step by Step Calibration
May 29, 2025I've been messing around with Smaart RTA, Rational Acoustics new iPhone app, on a few shows recently and wanted to make sure I got reliable SPL data. I don't think anyone makes a calibrator that fits an iPhone, so the next best thing is matching the microphone's readout to a know reference - like YOUR reference mic. Today I walk you through that exact procedure, step by step. And if you haven't calibrated your own measurement microphone before ever, you get that covered as a bonus!
