Description

***** "As a former IEEE Technical Committee Chair for Signal Processing, I find this app amazingly flexible and useful. Works very well with its proper designed-in control selections." - Roblake

Spectrum Analyzer for iOS is a powerful real-time audio analysis app. Designed with musicians and recording engineers in mind, it can also be used by anyone interested in the world of sound. Ideal for room tuning or speaker tuning, the app enables portable, precision audio measurement and visualization.

Feature Highlights:
● Octave Band Real Time Analyzer
● FFT Plot (Fast Fourier Transform)
● Spectrograph module
● Test Tone and White/Pink Noise Generator
● Native iPhone X graphics

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.

How to upload mic cal file?

I can’t upload anything in the mic section. How do you upload a file when it doesn’t let you? I click on it and it just exits out of the mic screen. Please fix.

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.

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.
