Of course, they are taught by older MDs, who < know what things sound like through hollow tubes ... < < Ed Nather One of the hot things in Digital Signal processing is taking old records from greats like Caruruso and filtering out some of the negative effects of the recording equipment used in those days. You wind up with some rather nice sounding records. You should be able to process the signal from a microphone and make it sound like it came through a hollow tube in the same manner. Just what the doctor ordered! Plus you can add controls that let them change the filter charcteristics to enhance certain sounds and a recording jack to help document the case. Now you have something that meets all of their expectations plus some additional value. If you go to the trouble of figuring out why a product isn't selling then fix it. John Eaton !hplabs!hp-pcd!john
