Spectrum Pad

Audio Spectrum Analyzer App for the iPad

Spectrum Pad turns your iPad 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 128 to 131072 bins.

Logarithmic display is available, and the graph fill mode can be turned on and off.

Visit the Spectrum Pad FAQ page for full details on how to use the app.
