# v 2.4 included threading to avoid screen lockups
# v2.5 working on FIR/IIR filter addition
# increase update speed of display loop
# added BOLD text to selected radio button
# add new radio button fuction "Spectrogram"
# fixed - each band of spextrogram properly displayed
# window prevented from resize (to preserve button positions)
# added (with considerable effort) a spectrogram to display freq & Tame data
# added a scale bar (which only appears in spectrum/spectrogram plots) to adjust FFT sample size
# spectrum plots now in dB
# one side spectral outputs now scaled correctly and include a hanning window
