Lifecycle of the APO is ruled by Audio Engine, but basically it is as follows:
Initialize ->LockForProcess -> APOProcess (actual data processing) ->
UnlockForProcess

Hi All,
Is there any documentation or blog where I can get the API flow diagram
for APO. I am trying to understand more about EFX and SFX. Currently I am not
able to find any information regarding these two.
Please advise on this.
Regards
