Hi Everyone.
I am currently looking through ComplexPlayThru in order to understand
it better. One of the tests I've been doing is to use Soundflower
as the input, and built-in-audio as the output. Assuming both use
the sample sample rate (which they do, as confirmed in AMS) things
work fine.
If I change the default output device to use a sample rate of 48000,
then things are not quite as rosy. There is about 1s worth of audio
played, which is at a lower pitch (I think the varispeed conversion
ration was about 0.91 or thereabouts), and then it goes pear shaped.
Pear shaped, for the moment I don't mind. What's confusing me is
that I would have thought he varispeed unit would have accounted for
the differences in sample rate, and therefore the audio wouldn't be
heard at a different pitch. Is this correct?
Regards,
Neil Clayton
