SPAN Plusis a real-time "fast Fourier transform” audio spectrum analyzer AAX, AudioUnit, and VST plugin for professional music and audio production applications.

SPAN Plus is an extended version of the freeware SPAN plugin: SPAN Plus provides several additional features such as PNG file export, real-time spectrum import/export for multi-track spectrum comparisons, static spectrums display, and a "wide” display mode.

SPAN Plus 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.

Beside multi-track spectrum comparison, SPAN Plus supports multi-channel analysis and can be set to display spectrums from two different channels or channel groups at the same time. Spectrum's color can be chosen to taste.

What's New

Version 1.23, February 17, 2023:

Fixed an issue with product key entry via the Paste button.

Version 1.22, January 17, 2023:

Removed SSSE3 requirement on Windows.

Reduced visual tearing on Windows.

Increased averaged spectrum calculation performance thus reducing time it takes to update the GUI.

Improved spectrum averaging precision for >1/3oct.

Static spectrum's name is now assigned/changed on "Take" only if it is currently "unnamed".

Changed FFT analyzer's minimal averaging time to 5ms (down from 50ms).

Changed static spectrum shift range to -42..42 dB (up from -32..32).

Added a small delay to the "Max Crest Factor" estimation, to reduce over-reaction to transients at playback start.

Fixed a system DPI scaling-related VST3 GUI resizing issue in Cubase, on Windows.
