What complexity do they use?
'norm'
Can I control it?
no
I'll file feature request to make complexity controllable.
BTW, changing kAudioUnitProperty_SampleRateConverterComplexity
seems to do nothing with AUConverter (while the SetPropety call
returns noErr). Isn't that a bug?
It should be implemented with AUConverter , but it isn't with the
varispeed

No - but what you do is a "latency pull" - you pull at least as
much latency samples through the AU providing correct input and
then throw out latency num samples of the output of the AU, then
you are good to go.
Though it is a bit convoluted, you can have a look at auprocess in
the examples, it does all of this for you
Thank you, I'll check this.
Mike
