Description

SPAN Plus is a real-time “fast Fourier transform” audio spectrum analyzer AU and VST plugin 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 plugin: 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-system metering (including calibration K-system metering). SPAN Plus displays level metering statistics, headroom estimation and clipping detection. Correlation metering is available as well.

Who Uses Plugin Alliance?

...$25 in the Madness rotation sale which has all of this and more. Sir Audio Tools and Voxengo SPAN Plus are < $45 without any sale. From all the misses in the PA catalogue this easily takes crown, for me. YMMV, as usual.

Best Spectrum Analyzer Plugin

Try clicking on "Static", and an additional window should pop up. Here you do a "take" of the current graph and it will remain in your display. (Please note: I'm working with the paid version Span Plus. Should you use the free version, I don't know if it has that functionality available.)
