Still the case

I'm considering using AUAudioFilePlayer, but while researching it I
found a post from July, by Bill Stewart, stating that it doesn't
support offline rendering:

What I've tried:
- setting the kAudioUnitProperty_OfflineRender property. It's not
supported by AUAudioFilePlayer it seems (but I believe this
doesn't mean
that the file player can't be used at all in an offline context).
Currently, that is the case (and this is the cause of the problem).
As you are in an offline context, you could use the
ExtendedAudioFile API directly (so instead of connecting the
AUFilePlayer, you could use a callback and in the callback use the
ExtAudioFileRead call - it should work fairly easily I think).
Is this still the case in Leopard?
