yes - they use the same underlying resampler
Do they use the same resampler as in AudioConverter?
With AudioConverter I can specify both complexity and quality, while
with AUConverter and AUVarispeed only "quality". What complexity do
they use? Can I control it?
I also found that they produce initial zeroes in output frames, while
AudioConverter result doesn't have it. I attribute it to the values of
primeMethod & primeInfo that are controllable with AudioConverter,
(however I haven't figured out yet how to actually control these
values
correctly with AudioConverter). Anyway, is there a way to control
prime
information with AUConverter/AUVarispeed?
