Hi all, wanting to build a frequency display something of the form of:

image

Is there anything in the new DSP library to make this kind of visualisation fairly straightforward? thx

Nope… It’s actually complicated and not complicated at the same time.
Not complicated because it’s a call to FFT, which is provided by JUCE, and because you have the OpenGL component for fast display.
Complicated because you need to bin the frequencies together and because you have to use OpenGL3 for performance.

ok, thanks. I’ll look into FFT.
