Frequently asked questions

A first measurement, then one after each adjustment. Every measurement is saved in the Library, where you can compare it with the previous one and see what changed.

The result applies to the spot where you hold the iPhone. Measure from the seat you use most; to get an idea of the others, take one measurement for each, at the same volume, and compare them.

They're two different starting points. Try both, one at a time, and use the Summation check to see which one plays better with your speakers in your room.

Slope measures what comes out of your speakers, correction included. Either way is fine, as long as it stays the same across all the measurements you want to compare. If you want to see how the room sounds without correction, turn it off before measuring.

Slope measures what's playing: if both subs play together, you see their sum. To adjust one at a time, turn the other off during the measurement.

You can still run the session: answer I don't know to the polarity question. Without a way to invert the phase, though, the Summation check can't compare the two positions.

Yes: Slope uses the built-in microphone of the device it runs on. Each device has its own microphone, so compare measurements taken with the same iPhone or the same iPad.

From a measurement you can share the PDF summary, with graph, key values and suggestions, or the Slope document, which opens in Slope on another device.

Yes: in Settings, under Guide, you'll find the Slope Tour. It teaches you to read a response and changes nothing in your measurements.
