[feature suggestion] [2D Spectrogram] analyze low frequencies with one FFT Size and high frequencies with another FFT Size

[axredneck]

e.g.:

• Capture some sound
• Analyze it with big FFT Size
• Render lower frequencies of FFT result
• Analyze if with small FFT Size
• Render higher frequencies of FFT result
• Maybe analyze it with medium FFT Size and render medium frequencies
• Scroll the spectrogram
• Repeat
  Possible advantages:
• Low frequencies would look sharper along frequency axis
• High frequencies would look sharper along time axis

Better suggestion: make something like this but without a gap between graphs and maybe 3 graphs instead of 2:

Something like implementing a CQT spectrogram would probably be a better solution long term

I can try adding a CQT 2D spectrum using gaborator on a fork of the repo during the next few days
