Beads library - FFT values??

in Contributed Library Questions • 1 year ago

Hi!

I'm new to this library (and in audio libraries generally) and i'm trying to use the FFT function. Does anyone know the maximum value returned when features[x] is called? I've seen values up to 2000!

float[] features = ps.getFeatures(); <-- just a 1D features array, nice and simple.

Thanks :)

I haven't used the Beads library yet, and the JavaDoc doesn't tell much.
I guess that the range of values is highly dependent on the produced sound, or on the sample data, etc.
You can loop over the obtained array and find the min and max values to use them in visualization.

Yea I couldn't find anything in the descriptions either! I'll do that and see what I get :)
