FYI, some time has elapsed with one soundcard instead of two and the slow cycle is still present, same period, and the phase of the slow cycle did not make a step change.
Now I must take a careful look at how the centroid is being determined, the resampling, RC temperature, etc. Maybe the 'sawtoothness' of the cycle should be telling me something. If nothing jumps out at me, I'll change the rise/fall time constants of the RC network and see if that alters the slow cycle. -- Paul Nicholson http://abelian.org -- _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
