Voxengo SPAN

SPAN is a "fast Fourier transform" audio spectrum analyzer plug-in that analyzes audio real time.

Span is derived from Voxengo's GlissEQ dynamic parametric equalizer and copies its spectrum analysis functionality. Span offers flexible options when analyzing audio. For example you can specify FFT window overlap percentage and Fourier block size in samples. You can also select a secondary spectrum for comparison and you can smooth out the spectrum for easier visual examination.

Span can analyze multiple channels and you can display the spectrum of different channel groups at the same time.

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
