1 year ago I'll wait to see how many people actually care but I'm pretty sure almost nobody will use any of those and it'll just be more confusing and cause users to chose windows at random instead.
Remember SDR++ is a receiver. It is not (and never will be) a spectrum analyzer. Not only does the FFT not work by default in a mode where any signal is intercepted, but SDR doesn't give any calibrated amplitude measurement so wanting to get absolute data out of the spectrum is futile.
Hi there,
I'm a user of SDR++, and I'm very impressed with the software so far. One feature that I think would be really useful is the ability to choose from a wider range of FFT window functions. Some examples of window functions that I'd like to see included are:
Hann window: This window function has a smooth roll-off and low sidelobes, making it well-suited for spectral analysis applications.
Kaiser window: This window function can be customized to have a user-specified sidelobe attenuation level, making it very useful for applications where sidelobe suppression is important.
Hamming window: This window function has a good tradeoff between frequency resolution and sidelobe attenuation, and is often used in spectral analysis and signal processing applications.
Flat top window: This window function has a very flat frequency response, making it ideal for applications where precise amplitude measurements are required.
I believe that adding these window functions (and potentially others) would greatly enhance the functionality of SDR++ and make it more useful for a wider range of radio receiver applications. Thank you for considering this request.
