About Spectrum Analyzer RTA

***** "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.

● 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.
