Increase FFT range #179

Closed devnulling closed 3 years ago

devnulling commented 3 years ago

This change increases the FFT range, which is helpful on ultra wide band captures.

I appreciate the PR, but I'd prefer to hold off on this for the moment. The problem is that right now the spectrogram plotting happens in the UI thread. We mostly get away with it as it's fast enough for smaller FFTs, but once they're bumped up too large the whole UI will become unresponsive for seconds at a time while the plot is drawn. Once that is threaded properly, I'm happy to increase the limit.
