OK so far I love this software - but in some instances when using the FFT Analyzer, I would like to obtain better frequency resolution over a narrow bandwidth of my choosing (like, say, 500-800Hz).  I've maxed out sample rate (96k) and minimized freq span (6kHz) but I still find myself wanting more frequency resolution.

This could also apply to the Spectrogram.

Is there anything I can do?

Reducing your sample rate will enable finer frequency resolution.

OK - slightly better but still bumpier than I'd prefer. 

Is there no way to concentrate the freq resolution within a specific user-defined window?
