Voxengo has announced the release of SPAN Plus version 1.4, an extended real-time “fast Fourier transform” audio spectrum analyzer plugin for Windows and Mac.

SPAN Plus is an extended version of the freeware SPAN plugin, providing 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.

Changes in SPAN Plus v1.4

  • Added “Spectrum Offset” display modes.
  • Fixed “zoom in” function’s issue.

SPAN Plus (VST/AU/AAX) is available for purchase for $44.95 USD. A demo version of SPAN Plus can be downloaded.
