SPAN is a real-time “fast Fourier transform” audio spectrum analyzer plug-in 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.

Changes in SPAN v2.1

• Global options saving problem fixed.
• Clicking on the control surface now resets spectrums in all channel groups.
• “Show All Channel Meters” duplicate meters issue fixed.
• Incorrect spectrum’s power readout on zoom-in fixed.
• Incorrect correlation metering on anti-phase signal fixed.
• Graphics drawing performance improved considerably.
• Scroller positions are now preserved when the user interface closes.

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