One thing that struck me about your description of Stopper's software was the delay in time between playing the note and seeing it displayed. I wonder if he has it set up to "skip the prompt tone" and just listen to the sustained tone in some fashion. A lot of the confusion in reading displays comes down to the prompt tone being different (usually noticeably sharp), so you see one thing, and then it shifts gears and shows you something else. Not very intuitive to follow. You can learn to ignore the prompt display, but it is hard to control reflexes. You also note that the display is very stable. I speculate that the software does some kind of smoothing operation, which could be in the form of averaging over very short spans of time, or perhaps throwing out pitches it identifies as anomalous. Jumpy display syndrome is the bane of the ETD. We learn (some of us, anyway) to "read through" and interpret, but it sure would be nice if the machine calculated and figured out what we wanted to be listening for, and displayed it. So maybe Stopper has figured out how to do that, in which case a big bravo to him! Regards, Fred Sturm University of New Mexico fssturm at unm.edu
