I'd think it's worldwide, but mainly among musicians and musical instrument tech folks - "one cent" being one hundredth of a semitone is a universal measure in tuning musical instruments. Cheap electronic guitar tuners (the ones with an old analog meter with a needle, or newer LCD simulations of same, or even two-digit digital displays) display the frequency error in cents. > >Cheers, >David _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
