How to get (weighted) octave values

[vor0nwe]

Hello,

I’d like to use the AudioLab-components to create a (rudimentary) octave analyzer.

I’ve managed to create a scrope graph, which displays the amplitude versus frequency all right. So far, so good.

Now I’d like to get amplitude for a specific frequency band (either an octave, or for 1/3 octave). Where can I access that?

Also, I’ll be wanting to apply acoustic weighting. Is that supported out-of-the-box, or will I have to do that myself?
