SPAN is a real-time FFT spectrum analyzer. For the most part it was derived from Voxengo's GlissEQ and CurveEQ professional equalizers and it reproduces their spectrum analysis functionality.




Parameters:

* Block - specifies the block size of the FFT (Fast Fourier Transform) spectrum analyzer.
* Speed - specifies the speed (averaging coefficient) of the spectrum analyzer.
* Slope - allows you to adjust the spectrum analyzer display slope towards higher frequencies.
* Channel - specifies which audio channel gets analyzed. "Avg" means the average of the L and R channels will be analyzed. "Max" means the maximum of the L and R channels will be analyzed.
* Monitor - specifies the monitoring mode. "RealT" means real-time spectrum is displayed. "Avg" means "average of all time" is displayed. "Max" means "maximum of all time" is displayed.
