Voxengo has released version 2.6 of SPAN, a free real-time “fast Fourier transform” audio spectrum analyzer effect plug-in for Windows and Mac.
For the most part it was derived from Voxengo GlissEQ dynamic parametric equalizer and reproduces its spectrum analysis functionality. SPAN is available in AudioUnit, VST and now VST3 plug-in formats (including native 64-bit support), for Mac OS X (v10.5 and later), and Windows computers.
Changes in SPAN v2.6
- Right-clicking on the spectrum will copy the frequency pointer to the clipboard.
- “dBFS.30″ and “dBFS.15″ metering options added.
- 1/9 and 1/12 octave smoothing options added.
- 65536 block size option added.
SPAN is available to download as a freeware effect plug-in.
