Ive been using the juce fft class for some time now and the bad resolution for low frequencies really bothers me. Im currently aware of two solutions and I know there are already threads out there, but I really want to know what the common approach is.

Implementing my own cqt transform?

Switching to some sort of fft with overlapping buffers?

A combination of both above?

Or is there another way to get high order ffts with good performance?
