Voxengo SPAN free spectrum analyzer plugin updated to v3.6

0

Voxengo has released an update to its SPAN free real-time “fast Fourier transform” audio spectrum analyzer plugin for Windows and Mac.

Voxengo SPAN 3.6

Version 3.6 includes new “Align 0 dB” spectrum display mode, enabling alignment of stationary 1 kHz sinewave of 0 dBFS peak level to 0 dB visual level, irrespective of the “Block Size” setting.

This mode may be useful for precise technical analysis of signals. When this mode is enabled, you may also need to set the “Slope” to 0, and adjust the “Range Low” and “Range High” values.

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 v3.6

  • Added the “Align 0 dB” spectrum display mode.
  • Fixed a minor frequency drift on deep zoom-in.
  • Fixed a minor spectrum power shift in non-Hann window modes.

SPAN is available as a free download in VST/VST3, AU and AAX formats from Voxengo and distributor Plugin Boutique.
