Voxengo SPAN 3.6 (Win/Mac) Free
10.2019 | 35.5 MB
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.
SPAN 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 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 also features output level metering with adjustable ballistics and integration time, EBU R128, K-system metering (including calibration K-system metering). SPAN displays level metering statistics, headroom estimation and true peak clipping detection. Correlation metering is available as well.

This audio plugin can be loaded into any audio host application that conforms to the AudioUnit or VST plugin specification. Plugins with AAX version available can be loaded in ProTools 12+.
This plugin is compatible with Windows (32- and 64-bit Windows XP, Vista, 7, 8, 10 and later versions) and macOS (10.7 and later versions, 64-bit Intel processor-based) computers (2.5 GHz dual-core or faster processor with at least 4 GB of system RAM, SSE4.2 instructions support required, e.g. any Intel Core i-, AMD Bulldozer- or Zen-based processor). A separate binary distribution file is available for each target computer platform and audio plugin specification. If supported on a specific processor, the plugin may internally utilize AVX2-optimized code.
Compatible Windows and macOS plugin software: Cubase, Logic Pro, ProTools, Ableton Live, Reaper, Presonus Studio One, FL Studio, Cakewalk, Nuendo, WaveLab, GarageBand, Vegas, SoundForge, Audition, Samplitude, Digital Performer, Mixcraft, Bitwig Studio, Edius, others.
If you cannot get plugin to work on macOS High Sierra/Mojave, you have to logout from the system and login again, it's a known issue not caused by plugin's own bug.
List of changes in version 3.6:
Fixed a minor frequency drift on deep zoom-in.
Fixed a minor spectrum power shift in non-Hann window modes.
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 switch 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.
