Unmuffle is formed from "un-" (meaning not or opposite of) and "muffle" (from Old French *mufler*, meaning to wrap up or cover). The word means to remove the covering or obstruction, allowing sound or clarity to emerge.
Think of 'un-' meaning not or the opposite, and 'muffle' meaning to cover or wrap up. So, to unmuffle is to remove the covering, letting the sound be clear.
