Ben: Please try out my idea if you would be so kind. Take the speech audio output of a ADC and program each individual bit to be the complement of the original output. In other words where there is a one, program it to be a zero. Likewise, where ever the output is zero, program it to be 1. I think that by so doing the final audio output will be a great deal more understandable. If you want more details on the basis for this I will gladly provide it. I have no equipment in which I can try this out and that is why I am asking this favor of you. Thanks so very much. Nate Almond
