Sep 1, 2013: Voxengo SPAN version 2.6 update is now available for download.  SPAN is a free real-time “fast Fourier transform” audio spectrum analyzer plugin for professional music and audio production applications.  For the most part it was derived from Voxengo GlissEQ dynamic parametric equalizer and reproduces its spectrum analysis functionality.  SPAN is available in AudioUnit, VST and now VST3 plug-in formats (including native 64-bit support), for Mac OS X (v10.5 and later), and Windows computers.

List of changes in version 2.6:

  • Right-clicking on the spectrum will copy the frequency pointer to the clipboard.
  • "dBFS.30" and "dBFS.15" metering options added.
  • 1/9 and 1/12 octave smoothing options added.
  • 65536 block size option added.

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 features:

  • Output signal power statistics
  • Spectrum smoothing
  • User interface window resizing
  • Clipping statistics
  • Correlation meter
  • K-metering
  • Stereo and multi-channel analysis
  • Mid/side analysis
  • Internal channel routing
  • Channel grouping
  • Preset manager
  • Undo/redo history
  • A/B comparisons
  • Contextual hint messages
  • All sample rates support
