Voxengo has released version 3.0 of SPAN, a free real-time “fast Fourier transform” audio spectrum analyzer plugin for Windows and Mac.
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 also features output level metering with adjustable ballistics and integration time, K-system metering (including calibration K-system metering). SPAN displays level metering statistics, headroom estimation and clipping detection. Correlation metering is available as well.
Changes in SPAN v3.0
- Added “RT Sigma” analyzer type.
- Added “Spectrum Offset” display modes.
- Made bottom group selector switchable.
- Fixed “zoom in” function’s issue.
SPAN is a free download for Windows and Mac (VST/AU/AAX).
