AKLite is a real time spectrum analyzer for the iPhone and iPad. It is a lite version of the Spectrum part of Audio Kit iPhone App, also by Sinusoid Pty Ltd.

FFT (Fast Fourier Transform) is used to calculate the frequencies in the Spectrum Analyser and these are displayed in real time. The frequency is displayed in either logarithmic or linear scale and this is selectable.
