frequency to pass, while frequencies that lie further away (the lows and highs) are
filtered out. A sound that contains lots of mid range frequencies is the result. Also see

frequency, while allowing the frequencies that lie further away to pass. The mid range
frequencies will become softer and the lows and highs remain unchanged.
