Ranger app for iPhone and iPad

Ranger is a 31 band audio spectrum analyser complete with a peak band histogram, microphone input level meter, frequency readout and a comprehensive music instrument frequency range library.

Ranger provides information regarding frequency ranges (fundamental, 2nd, 3rd and 4th harmonics) of over 30 music instruments along with five general ranges (sub-bass, bass, midrange, high mids and highs).

View the maximum and minimum bands for the range that is selected.

Use the frequency readout to assist with monitoring feedback. The frequency readout stabilises when a strong sinusoidal wave is present in the input signal.
