Audio input may be acquired via the built-in microphone or an external measurement microphone. For best results we recommend using a calibrated measurement microphone connected via USB audio interface or iPhone dock connector. This allows for high precision and flat frequency response, as well as for stereo input.

Excellent app

This app works great and have a very pleasing look and feel. I design sound systems and this app is useful to get a visual on how my system is performing. This app is also going to be useful for training or testing employees. The app does what it's supposed to and if you get a good external mic it becomes a lot more precise. This tool is well worth the money and I really couldn't be more pleased with this purchase.

I was surprised how far to push my car stereo settings--nice!

Seems to work best if I attach the iPhone to the car via USB for pink noise generator, and use iPad for spectrum analysis. Doing both on the iPhone alone, the iPhone noticeably diminished the pink noise volume. I used iPhone 7+ and iPad Pro with iOS 10.3.2, and the screen is completely steady. Even with the iPhone 4S, the screen is completely steady.

I use this app for on the spot analysis of stringed instruments I construct and repair as well as checking out those I might purchase at retail. I find the octave RTA suits my purposes best. And you can't beat the price. Does the same thing as versions costing $75 or more.
