An echo chamber is a hollow enclosure used to produce reverberated sounds, usually for recording purposes. For example, the producers of a television or radio program might wish to produce the aural illusion that a conversation is taking place in a large room or a cave; these effects might be accomplished by playing the recording of the conversation inside an echo chamber, with an accompanying microphone to catch the reverberation. Nowadays, digital, algorithmic, and convolution reverbs are more widely used to create such effects, but echo chambers are still used today, such as the famous echo chambers at Capitol Studios.
