I recently created a quartz composer patch which will play a sound file in a Quartz Composer composition. It is very useful for playing a short sound file for a sound cue to an event or a basically any sound you want to include in a composition.
I created this patch for a toddler’s game in which the screen contains a bunch of objects which the toddler removes by moving the mouse over the objects. As each object is removed a very short sound file is played to give a audio cue that the object has been saved. It is also used in another animation to play a bubbles sound when fish are swimming by. I do offer it for sale along with support for a very reasonable $4.99. I made a short YouTube video to give some idea of what is does. It can be found here available here. It can be purchased here
