CarSweep: Car Audio Analyzer

Meet EQ Designer: CarSweep now learns the EQ of your own stereo. Every car stereo has its own EQ, and almost none of them tell you what a slider actually does. "Bass" can be a shelf below 60 Hz or a bump at 120 Hz, and one step can be half a decibel or two. Without knowing that, every setting is a guess. EQ Designer measures it. Tell CarSweep how many sliders you have, then move each one all the way up and all the way down while it listens. A few minutes later it knows every slider – filter type, frequency, width and dB per step – and EZ Tuning gives you the exact setting for each one, in your stereo's own steps. It works with any head unit that has an EQ, subwoofer slider included, and the iPhone microphone is enough. Your measured stereo then shows up wherever you pick your system. You will find EQ Designer on the home screen; it is part of CarSweep Pro.
