I am new to GNURadio. I need to do realtime FFT (GUI is not required).
I need to feed this FFT to other components of the system so I ned
simple FFT values of the signal. I tried hacking the fftsink2.py and
was able to get the values but the problem is that the rate of data is
very less. I am getting 15-16 FFTs in a second. This is too less.
Can you suggest me a way to improve this?
