FFT Lite is an ad-supported and limited feature version of the powerful Studio Six Digital FFT app, which is part of the AudioTools suite. FFT Lite uses the advanced FFT frequency analysis engine and microphone compensation from AudioTools, but removes most of the options and tools, such as the generator, screen GUI operations, and settings options.
Use FFT Lite to evaluate the performance of FFT, and upgrade to the full version by buying the in-app purchase if you wish to unlock all of the features.
See our demo video to see what options and tools will be available after upgrading.
FFT is a high-resolution audio analysis tool for the iPhone and iPod touch. It uses the Fast Fourier Transform to analyze incoming audio, and displays a very detailed graph of amplitude vs. frequency.
Use this app with the built-in iOS device microphone, or upgrade to our iAudioInterface2 or iTestMic for a complete professional solution.
*** Designed for Acoustical Analysis
This application has been designed for acoustics work, and so the bins have been normalized to octaves, to get a display that will show a flat line for pink noise.
The FFT size is fixed to 16k points in this app. It is a highly accurate and responsive acoustic analysis app.
Upgrade to get graph smoothing options, decay modes including peak and averaging, a signal generator, save/recall including compare modes, display multiple plots, tune the FFT parameters, add peak tracking, GUI options for zooming the graph, cursor readout, and much more.
