Our favourite free analyzer gets an update!. Good news today for those who aren’t splashing out on Live 9, SPAN is a free real-time “fast Fourier transform” audio spectrum analyzer 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 is available in AudioUnit and VST plug-in formats (including native 64-bit support), for Mac OS X (v10.5 and later), and Windows computers.
SPAN has proven to be a very flexible and malleable tool for spectrum analysing and if you don’t already own this free plugin, then you can download the new updated version from Voxengo’s site.
