Voxengo Span is a free real-time “fast Fourier transform” audio spectrum analyzer AAX, AudioUnit, and VST plugin for professional sound and music production applications. For the most part, it was derived from Voxengo GlissEQ dynamic parametric equalizer and reproduces its spectrum analysis functionality.

It provides you with a very flexible “mode” system which you can use to set up your spectrum analyzer preferences. You may specify Fourier block size in samples, FFT window overlap percentage, spectrum's visual slope. Besides that, you can choose to display the secondary spectrum of the desired type (e.g. real-time maximum, all-time maximum). Spectrum can be smoothed out visually for an easier examination.

It 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.

Voxengo Span also features output level metering with adjustable ballistics and integration time, K-system metering (including calibration K-system metering). Voxengo Span displays level metering statistics, headroom estimation, and clipping detection.  Correlation metering is available as well.

Voxengo Span 3.16

Voxengo Span 3.15
- Changed spectrum's "Freq Lo" maximum to 500 Hz (down from 1000 Hz), and "Freq Hi" minimum to 600 (down from 2000 Hz), to permit finer low- and mid-frequency range selections
- Added the "Spectrum, meter border" palette modifier. Updated palettes.
- Made a small speed-up of GUI loading and drawing
- Fixed an issue with popup-menus not functioning in Logic Pro on Apple M1 native
- Implemented "Portable Setups" support (portable settings), read more in the Primary User Guide


Voxengo Span 3.14
- Change log not available for this version


Voxengo Span 3.13
- Added the "Large Cursor Readouts" plug-in setting which enables larger mouse position readouts, useful when the plug-in is placed on a distant dedicated monitor
- Fixed a drawing bug with the "Flat Panels" global switch disabled
- By frequent user request, the "Solo" switch's state is now saved together with the preset (a part of the routing parameters). While this opens up a possibility of leaving the "Solo" switch enabled and forgotten, this provides more flexibility, e.g. when mid/side processing is used.

Improved:
- overall graphics drawing performance
- anti-aliased line rendering of the secondary spectrum
- knob's renderings


Voxengo Span 3.12
- Added the "Panel border" palette modifier
- Updated all palettes, to reduce "border" contrast. An existing palette may need to be reloaded for the change to be visible
- Modified spectrum window's sliders to look less contrasted


Voxengo Span 3.11
- Added Apple Silicon native compatibility
- Added 1/48 octave spectrum smoothing option
- Improved spectrum smoothing precision
- Enabled the "asynchronous drawing" window mode on macOS; may fix the user interface "lagging"
- The "Copy to" button is now called the "Copy": this button now copies parameters FROM the selected group, NOT TO the selected group. This should improve the workflow
- Improved font rendering slightly


Voxengo Span 3.10
- Internal channel letters were changed to numbers
- Level meters can now display input channel names instead of internal channel indices
- Added "Stereo Swap" and "Stereo To Mono" routing presets
- Added AudioComponents interface to AudioUnit as the ".rsrc" interface may be deprecated in the future


Voxengo Span 3.9
- Change log not available for this version


Voxengo Span 3.8
- Added the preset list sorting function to the preset manager
- Redesigned the knob image
- Extended the "Color Editor" with color modifiers
- Added the "Gray Blue" and "Navy" color schemes
- Implemented "anti-aliased" line drawing optimization
- Fixed a bug where the "Hold" switch was not holding statistics


Voxengo Span 3.7
- Version 3.7 adds the "True Peak/Sample Peak" switch which can be used to switch between true peak and sample peak indication


Voxengo Span 3.6
- Added the "Align 0 dB" spectrum display mode. This mode enables 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


Voxengo Span 3.6
- Fixed a minor frequency drift on deep zoom-in
- Fixed a minor spectrum power shift in non-Hann window modes


Voxengo Span 3.5
- Improved responsiveness during window resizing
- Improved visual quality at different visual interface scales
- Windows: implemented (switchable) higher-precision user interface update timer, for smoother display
