Voxengo has released SPAN Plus, a fast fourier transform spectrum analyzer VST/AU effect plug-in for Windows and Mac.
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.
