►► Get the updated Audio Toolkit 2025: https://www.producedbymkc.com/audioto... I'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! --- 🏗️ System Tuning Workshop For Beginners - https://www.producedbymkc.com/systemt... ⚒️ Audio Toolkit - https://www.producedbymkc.com/audioto... 🆕 New To Sound System Design?
