Voxengo has released SPAN v3.1, a free real-time fast Fourier transform audio spectrum analyzer effect plugin for Windows and Mac.
Changes in SPAN v3.1:
- Fixed solo band-sweeping function issue.
- Added 175% visual scale.
SPAN is a free real-time “fast Fourier transform” audio spectrum analyzer AU, AAX and VST plugin for professional music and audio 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.
