Mac Forum / Programming / CodeWarrior / December 2003audio play
Hello: I am trying to play a large file from the disk with the double buffer techniques in OSX. The old OS9 method does not work and I cannot get the callback function to work. Any Ideas?

Hello the good old way works just fine ( i use it in ptk : http://ptk.phelios.com ), You need to register the callbacks via NewSndCallBackUPP and free it via DisposeSndCallBackUPP http://developer.apple.com/documentation/QuickTime/RM/LegacyAPIs/SoundManager3.3 /index.html pat. |
