Dear Dave:
Thank you, thank you, thank you for working at compiling Jim Peter's code.
Jim Peter's code ran fine on my Win98/DOS System, but I know I do not have the software skill recompile it. Hopefully you will work out a system thatwill work on my PC so I can experiment with some code variations.
It is great that you (Dave) are close enough for a phone call in case I getstuck.
Dear Jim Peters:
I know that you are on "your own" path and want to "only" work on filters. I really appreciate the work you have done to make this much available, but I have some other things that I would like to see developed. I do not know if you have time or interest to work on this or whether some of the other programmers could jump in now that you have gotten us started. ( Dave?)
>From a user's perspective I would want to have a better oscilloscope display of the raw waveform data. Two channels slightly offset and 1 inch largerwill let you see whether what you are looking at is real data or an artifact. The filter (voice print) output does not tell enough of a story. So far I find the FFT waterfall display is easier to interpret. But I have to agree with you that the log display is better. ( see me eating humble pie )
What would be nice is to have some menu options as to how the data is to bedisplayed. Would it be possible to display the FFT waterfall as an option?
Thank you again for getting the software part of the project up and running!

I'll check into that, as it seems more likely this is a FFTW problem rather
than SDL or GCC. The graphics worked great, what was being displayed is in
question. If you want to see the screens + my compiled version of BWView, it
is at http://www.psychosensory.com/files/bwview-screens.zip. But it sounds
like it is probably a clash either between the Debian install/manual compile,
or linkage with the 64-bit libraries.

Whoops! I knew that--my typo.
Dave.
