Description

SPAN is a free real-time “fast Fourier transform” audio spectrum analyzer AAX, AudioUnit and VST plugin for professional sound and music production applications.

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.

Applications

  • Fast Fourier transform spectrum analyzer
  • Stereo, mid-side, surround spectrum analyzer
  • Stereo correlation meter
  • EBU R128, K-system meter
  • RMS, true peak level and clipping detector

Airwindows BitGlitter: Mac/Windows/Linux AU/VST

...more opaque sound which still lacks modern digital 'edge': you can plainly see on a metering plugin like Voxengo SPAN how the highs are softened. It's not a digital bright-maker, it's a texture-changer and impact-maker. Especially if you go for darker regions of the Bit Glitter control, you can use this to add ridiculous...

Gear for softer/spongy high end

Have you checked the overall spectral balance of your mix with Voxengo SPAN? At a 3 dB/Octave slope, the high end should look flat at most, maybe dropping down a bit. If it's not, you may be compensating for a lack of treble in your room. Also, a plugin combo to try out: Waves TG12345...
