Voxengo has released version 2.7 of SPAN, a free real-time “fast Fourier transform” audio spectrum analyzer effect 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.


Changes in SPAN v2.7

  • Increased “smoothed” graph drawing precision.
  • Fixed crash when 1/12 octave smoothing is enabled.
  • Increased overall spectrum drawing precision.


SPAN is available to download as a freeware plug-in for Windows and Mac (VST/AU).
