A plastic structure separates white noise into pitches, like a rainbow splits light into colors, offering a novel way to manipulate sound.

Apart from the ARE, the researchers also designed a lambda splitter that takes in a mix of sound frequencies and directs low and high-frequency sound waves in different directions.
