SPAN Plus is a real-time "fast Fourier transform" audio spectrum
analyzer plug-in for professional music and audio production
applications. For the most part it was derived from Voxengo GlissEQ
dynamic parametric equalizer and reproduces its spectrum analysis
functionality. SPAN Plus is an extended version of the freeware SPAN
plug-in: SPAN Plus provides several additional features such as PNG
file export, real-time spectrum import/export and static spectrums
display.

SPAN Plus 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 Plus 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 Plus also features output level metering with adjustable
ballistics and integration time, K-metering (including calibration
K-metering). SPAN Plus displays level metering statistics, headroom
estimation and clipping detection. Correlation metering is available
as well.
