Description

RTA Pro is a real time audio spektrum analyzer. It turns your iOS device into a powerful audio test system usually seen only in audio research laboratories and music studios. Such instruments are used to analyze the frequency spectrum of ambient noise, e.g. to be able to pinpoint frequencies which cause rumble in a room. Another use is the level setting setting of PA systems for concerts. Features: RTA Pro requires iOS11 or later and has been calibrated for the microphones of most iPhones. Custom calibration is also possible. The frequency range is 32Hz to 16kHz. Linear display, as well as weightings for measuring dB(A) and dB(C) is provided. Apart from 1/3 Octave Bands and Octave Bands, RTA Pro also features the display of a Fast Fourier Transform (FFT). The speed is adjustable to impulse, 128ms and 1 second.
