Caleb gives a good introduction and overview of how to think about the problem. In your particular case, here are some of the pieces you would might have given your description:

• Clip (M) - Responsible for holding the actual audio data. It would know how to interpret the data and given information about it, but it wouldn't actually play anything.

• Player (V) - Actually plays a clip on the speakers. Yes, that's a kind of view in MVC. Audio is just another kind of presentation. That said, you'd never call it "PlayerView" because that would suggest it were a subclass of UIView.

• PlayerView (V) - A screen representation of the Player. Knows nothing about Clips.

• ClipManager (C) - An object that would keep track of all the clips in the system and manage fetching them from the network, adding and removing them to caches, etc.

• PlayerViewController (C) - Retrieves a Clip from the ClipManager, and coordinates a Player and a PlayerView to display and play it, as well as any other UI elements (like a "back button" or the like).

This is just an example of how you might break it down for some theoretical audio player app. There are many correct MVC ways to do it, but this is one way to think about it.
