To check up on the varispeed, I would log the timestamps it pulls you
for, e.g.:
pull 1:
It pulls you at time 1000 for 500 samples.
pull 2:
is the timestamp 1500? if not, error
time 1500, 499 samples
pull 3:
is the timestamp 1999? if not, error
If the timestamps aren't correct, let us know ... if they are, then
check your code further ...
I checked the time stamps using break points. The results are as
follows:
Pull sTime (output) # sTime (input) #
1 37,220,394 1116 16,721,708 512
2 42,873,218 1112 19,318,474 512
3 49,666,285 1116 22,439,039 512
4 55,237,383 1116 24,998,262 512
pulling at 96Ksps, VariSpeed converting to 44.1Ksps on it's input side.
This rate conversion appears to be working from the requested sample
numbers. The sample times however are all over the place. The delta
between pull 1 and 2 on the input side of the VariSpeed is >58 seconds
at 44.1Ksps. It took less than 20 seconds for me to write down the
numbers and continue execution, so the numbers don't seem to account
for that either.
Any ideas?
Ethan...
