[Expand Summary]
Reverberation is a property of concert halls that greatly adds to the enjoyment of a musical performance. Sound waves propagate directly from the stage to the listener, and also reflect from the floor, walls, ceiling, and back wall of the stage to create myriad copies of the direct sound that are time-delayed and reduced in intensity. In this module, learn about the concept of reverberation in more detail and ways to emulate reverberation using a digital filter structure known as a comb filter.
