Re: CABasicAnimation : Can I run a CABasicAnimation and get it's updated values on it's progress?
AudioQueueTimelineRef does not seem like it would let me make calls against it, so much as receive notifications from it. Do I have the wrong timeline or am I misunderstanding AudioQueueTimelineRef or am I completely missing the timeline you are talking about?

Re: CABasicAnimation : Can I run a CABasicAnimation and get it's updated values on it's progress?
There are likely some Core Audio gurus around the list that can help you with that. I'm not terribly familiar with it. I know you can use QTKit to load and play back audio files. The QTMovie object has a function called - (void)setVolume:(float)volume. -Matt On Jan 16, 2009, at 11:39 AM, Adam Venturella wrote: Set the volume on an Audio Queue (make a fade out/fade in) So on the interval, I will call: AudioQueueSetParameter (queueObject, kAudioQueueParam_Volume, value ); Where value is 0-1 On Fri, Jan 16, 2009 at 10:34 AM, Matt Long > wrote: Yes.

Re: CABasicAnimation : Can I run a CABasicAnimation and get it's updated values on it's progress?
Set the volume on an Audio Queue (make a fade out/fade in) So on the interval, I will call: AudioQueueSetParameter (queueObject, kAudioQueueParam_Volume, value ); Where value is 0-1 On Fri, Jan 16, 2009 at 10:34 AM, Matt Long wrote: > Yes.
