Spectrum Pad
Spectrum Pad turns your iPhone, iPad or iPhone Touch into an audio spectrum analyzer. Frequencies up to 20 kHz can be displayed.
You can control the displayed frequency span, as well as the FFT size, from 1024 to 262144 bins. The larger the FFT size, the longer time between updates, but the higher the frequency resolution.
Logarithmic display is available, and the graph fill mode can be turned on and off.
Up to five frequency markers can also be displayed.
Buy your copy now, and have an audio spectrum analyzer with you, wherever you go.
