Voxengo has released an update to its SPAN Plus extended real-time “fast Fourier transform” audio spectrum analyzer plugin.

SPAN Plus is an extended version of the freeware SPAN plugin, which was also recently updated. 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.

Changes in SPAN Plus v1.5

  • Fixed issue with “Spectrum Offset” display modes.
  • Fixed display “notching” of high-resolution spectrum.
  • Added Retina support on macOS, and automatic high-resolution UI size adjustment on Windows.
  • Added “anti-aliasing” spectrum display mode.

SPAN Plus is available from Plugin Boutique for $44.95 USD. It supports VST/VST3, AU and AAX plugin formats.
