I have gotten around this problem in part by using my own recorded aural tunings which I record in the way we do for exams, by reading the fundamental starting at C5. The FAC program reads the 6th octave through the midrange, and fundamental starting at C6. This is my one criticism of the FAC, technically it is more accurate reading from an octave higher, but if the reading is poor that becomes a moot point. Perhaps it is not possible to calculate the FAC at the 6th octave but display it at the 5th octave throughout this range. You probably have noticed that the readings are somewhat better on fine pianos. Interestingly, I have noticed that the machine seems to get the clearest readings from right in front sitting on the stretcher, not far at all from where our human microphones are positioned. If these explanations don't make sense, give them a call. Dennis Johnson djohn@skypont.com
