http://www.reyburn.com/irct.html This page from a competitor's website cites an accuracy of 0.01 cents (which is musical terminology for 0.0000057). This is the industry standard for professional piano tuning devices. So an uncorrected 10^(-5) would not be competitive. That web page also mentions automatic calibration through something he calls the "CyberCloud" which I assumed was an NTP function through his server. I can't imagine how else he would do it. Of course his product is on the iPhone which does not have GC, so maybe that is the difference. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
