Voxengo has updated SPAN to version 3.10. SPAN is a free real-time "fast Fourier transform" audio spectrum analyzer plugin for professional music and audio production applications. SPAN is available in AudioUnit, AAX, VST, and VST3 plugin formats, for macOS and Windows computers.
The list of changes in version 3.10:
- Internal channel letters were changed to numbers.
- Level meters can now display input channel names instead of internal channel indices.
- Added "Stereo Swap" and "Stereo To Mono" routing presets.
- Added AudioComponents interface to AudioUnit as the ".rsrc" interface may be deprecated in the future.
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.
