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.

The area under the line trace can be optionally filled or left blank.

The FFT length used in AKLite is 2048, giving good resolution of frequencies. Interpolation gives resolution to within 1Hz.

A Bartlett FFT window type is used for calculations and there are 3 FFT windows used.

The strongest frequency is displayed above the peak

Very basic but did the job. I used this to track down the source of an annoying noise in my house.
