The real difference between the two methods is 'sample count'
versus 'time' as the source of the event that starts a period.
I always wondered why one would use a timer, it just amounts
to polling. Suppose you look every 1 ms to check if there
are enough samples for a period. That means you can be up
to 1 ms late. Compare that to the period time of 1.33 ms
when using 64 samples / 48 kHz. Up to 3/4 of the available
time to compute a period could be lost...
Or am I missing something ?
