Hi,
I'm looking to use the built-in Core Audio sample rate converter on OS X such that I get the highest quality output. To that end, I'm using the Pre prime method, however in the callback the PrimeInfo struct always has 0 for leading and trailing frames. I do notice that the first call to the callback requests more frames than subsequent calls, but it isn't clear to me when to provide leading or trailing frames. The only time leading and trailing frames are non-zero, is if I set None for the prime method.
Am I doing something wrong?
Also, I am trying to understand what the initial phase setting means. Does this control the amount of pre-ring vs. post-ring? If not, what kind of audible effect would this option have?
Thanks!
