Description by Josef Dave Llorente Written by the developer, not by AppBrain. Click to read.

Spectrum Analyzer – Audio FFT transforms your iPhone microphone into a real-time live audio spectrum workspace from 20 Hz to 20 kHz. Using Fast Fourier Transform (FFT) processing, it displays a log-scale frequency graph, live input sound meter, and a peak-frequency readout to pinpoint dominant tones. Easily freeze the display to inspect static audio data. Ideal for musicians, engineers, and students, core features are free, with an optional one-time Pro upgrade for higher FFT resolution.
