SPAN is a free real-time “fast Fourier transform” audio spectrum analyzer AAX, AudioUnit, and VST plugin for professional sound and music production applications.
SPAN provides you with a very flexible “mode” system which you can use to setup your spectrum analyzer preferences. You may specify Fourier block size in samples, FFT window overlap percentage, spectrum’s visual slope. Beside that you can choose to display secondary spectrum of a desired type (e.g. real-time maximum, all-time maximum). Spectrum can be smoothed out visually for an easier examination.
