Voxengo SPAN Plus 1.6 spectrum analyzer plugin released - Press Release
Jun 16, 2019: Voxengo is pleased to announce the release of SPAN Plus version 1.6 - 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 (including native 64-bit support), for macOS (v10.7 and later), 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 1.6 includes the following changes:
- Implemented EBU-R128 "LUFS" and "LU" metering modes.
- Implemented "True Peak" peak level and clippings detection.
- Added 1/24 octave spectrum smoothing option.
- Added AIFF sound file support to Static spectrum load function.
- Increased resolution of saved static spectrum files.
- Added "Blackman" and "Hi-Res" spectrum window types.
This version improved smoothness of real-time graphics draws on Windows systems, now graphics is drawn with a lot better timing precision and less stuttering. This, however, may increase CPU load in comparison to the previous version: if this is unacceptable to you, simply decrease the "Frames Per Second" global Voxengo plugin setting.
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.
