That's my point - I was talking about native playback. When I said one  
line of code I meant Obj-C not shell, so you don't need any external  
application. To be precise to play an audio file all you do is
[[[NSSound initWithContentsOfFile:fileName byReference:YES]  
autorelease] play];
Thats' all :)
