I know that the frequency analyser is not a FFT one with 30 filter bands, but I'm wondering is it's possible to enhance the resolution in the future or for future hardware.

The hofa analyser for example can have 120 filter bands to show the spectrum (when I remember correctly).

Actually, I would love to see an equal detailed analyser suite like the Hofa analyser or the flux analyser. I would also pay for it. But that's just wishing.
