توضیحات زبان اصلی محصول:
SPAN is a free real-time “fast Fourier transform” audio spectrum 
analyzer AAX, AudioUnit and VST plugin for professional sound and music 
production applications. For the most part it was derived from Voxengo 
GlissEQ dynamic parametric equalizer and reproduces its spectrum 
analysis functionality.
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.
SPAN supports multi-channel analysis and can be set 
to display spectrums from two different channels or channel groups at 
the same time. Spectrum's color can be chosen to taste.
SPAN also
 features output level metering with adjustable ballistics and 
integration time, EBU R128, K-system metering (including calibration 
K-system metering). SPAN displays level metering statistics, headroom 
estimation and true peak clipping detection. Correlation metering is 
available as well
