Hi
I recently started working with Core Audio. I looked at couple of sample Apps an noticed that monitor UI code typically use a NSTimer to poll for the audio state they display. Typically this is done to create some sort of progress view or maybe a level monitor. An alternative would to use Key Value Observing. Has anyone tried this? I do not know much about ObjC Key Value Observing how ever I assume it makes heavy use of ObjC messaging and is probably to much over head?
Any suggestions?
Andy
