Pitch of an engine is dependent on RPM.
But sure the character of an engine sound changes as you change load.
Also the prop makes some noise of its own, and that certainly varies with load.
It might be cool to have a seperate blower sound. On DB engines the blower speed is independent of engine speed. And on the planes with two speed blowers, it would be cool to hear that thing shift when you reach a certain altitude.
