Voxengo has announced an update to the SPAN real-time “fast Fourier transform” audio spectrum analyzer plugin.
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.
Changes in SPAN v3.10
- 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 is available in VST/VST3, AU and AAX plugin formats for macOS and Windows.
