Dear Jim Peters:

Please compare your bwview display with the FFT waterfall and let me know "what you think" and which provides better data. This is not meant as a "mine is better than yours" discussion. At this point in the development of your bwview program, I believe the FFT waterfall works better. I hope you will incorporate it into your program as an option.

I really like the idea of the voice print display, and after you add color it will show a lot more.

I would also like to see the FFT waterfall display with a log frequency scale that you suggested a while ago.
  
The oscilloscope display is very important. Without looking at the brain wave display you cannot know what the FFT or voice print frequencies mean. A clipped waveform will produce a large number of "false" frequencies. It is also important to see the right and left hemisphere coherence.

If you look at the Downey file, you will see a series of low frequency pulses that look like eye blinks but are not. These have a Delta frequency component, but are half sine pulses that might be REM or sync pulses. Very interesting? I wish that I had 12 or 16 bit resolution while making this recording.

Oops -- sorry about that. I haven't looked at your web-site since I
downloaded the app all that time ago. I now have it more under
control.
