IDK if that's really the way you want to do it, but if I had to design some shit to turn 8kHz sound into 44.1 kHz, i'd perform a DFT on the signal, zero-pad the real and imaginary parts so the total length reaches the original size of the signal / 8 * 44.1, and then i'd IDFT it. Actually it's the only way I know to convert a sample rate, and it's fine I guess

i agree, for the most part. at Wikipedia, they call it "don't bite the newbie". there are other (unnamed) perennial jerk-offs that this might not apply to. hell, i might be one of them. :-) -- r b-j rbj@audioimagination.com "Imagination is more important than knowledge."

Radiologists are low on the MD totem pole. When I was working for a startup company that was trying to market to Cardiologists, I found out that there are turf wars between Radiologists and a number of other specialties. Cardiologists usually have their own ultrasound equipment. Orthropedic doctors will often have an in house Xray lab. They figure that since they have to look at the raw data anyway, why forgo the income of the procedure. They only tend to send people to radiologists for procedures like MRI's which require more expensive equipment. I think that if the US ever normalizes it's relationship with Cuba, the medical profession in the US will really start having to deal with international competition.

Those services are already being outsourced. Radiologist in India and Sri Lanka examine X ray images and report findings. Legal secretaries assemble boilerplate, all overseas.
