20-Feb-2020: Voxengo is happy to announce the release of SPAN Plus version 1.10 - an extended real-time “fast Fourier transform” audio spectrum analyzer plug-in for professional music and audio production applications. SPAN Plus is available in AAX, AudioUnit, VST and VST3 plug-in formats, for macOS and Windows computers.

SPAN Plus is an extended version of the freeware SPAN plug-in: SPAN Plus provides several additional features such as PNG file export, real-time spectrum import/export and static spectrums display.

Version 1.10 includes the following changes:

* Added the preset list sorting function to the preset manager.
* Added the "True Peak/Sample Peak" switch.
* Redesigned the knob image.
* Extended the "Color Editor" with color modifiers.
* Added the "Gray Blue" color scheme.


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.

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.

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

SPAN Plus features:

* Real-time spectrum import/export
* PNG file export
* Static spectrums display
* Output signal power statistics
* Spectrum smoothing
* User interface window resizing
* True peak and clipping statistics
* Correlation meter
* EBU R128 LUFS/LU metering
* 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
* All sample rates support
* Retina and HighDPI support

Demo version of SPAN Plus can be downloaded freely at the Voxengo web site: https://www.voxengo.com/product/spanplus/

Aleksey, I would buy the Span Plus immediately when it would support automatic instance setup. I'm waiting for this since years thinking... yes one day it will support it and then I will upgrade: :-)

Like drop Span Plus on channel 1, one on channel 2, ... and it's doing a setup automatically in a way that you see both spectrums in the plugin. Delete the plugin and this channel is removed. The manual way is too time consuming and complicated for me and therefore I use other analysers for multi channels, while Span is my favourite one for just one channel.

I have span plus but i agree with the above notion.
plugin intercommunication like iZotope or Fabfilter does it, where you can easily pull spectrum from any active instance (which is named after the track)

Thanks for your feedback. Currently, I have a limitation of backwards-compatiblity. Such easier selection of import tracks may be implemented in a future major update, not possible to implement in the current version.

Well, Voxengo was among the first to implement such feature in e.g. GlissEQ, others caught up much later, but with an improved user experience of course.
