Improving spectrum analyser and spectogram

FYI @taktik

This video is not dumb at all, he describes how to heavily improve the resolution of spectrograms in the low frequency area using “spectrum reassignment”. I think he actually nailed it. I guess this can be also applied for the anaylser mode. He also compares all the top notch analysers currently available:

Also the Renoise analyser - though surely better than the most - is certainly not precise in bass areas. It’s quite bad, if you use 44,1kHz instead 48kHz…
