Voxengo SPAN Plus 1.9
Description of Voxengo SPAN Plus 1.9
Voxengo is happy to announce the release of SPAN Plus version 1.9 – 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 1.9 includes the following changes:
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.
Fixed a minor spectrum power shift in non-Hann window modes.
Added FLAC file spectrum analysis.
macOS Catalina-compatible and notarized.
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.
