Interesting discussion. I don't think we have much to add to it at this point.

We have of course, our internal evaluations of the SRC that we've used as we've worked on this with Leopard. We also made some incremental improvements - bug fixes - in one of the Tiger SUs. However, I don't think its totally appropriate to publish these figures ourselves; I'd rather see an objective evaluation so that any question of bias is removed. We would be happy to participate or help out though if that is necessary or useful.

As for usage, Logic and Sound Track are both using the SRC that is provided through the AudioConverter; I don't know however what the default quality setting is, or if this is placed in the hands of the user to change. The same is true for both QuickTime and iTunes too for that matter. The QT Exporter also provides a setting to adjust the quality of the SRC used in the export operation. So, there is no "iTunes SRC" or "Core Audio SRC", etc.. its just the same SRC being run at a different quality setting. That's why we thought we should make it good!

Thanks

Bill
