An echo chamber is a hollow enclosure used to produce reverberation, usually for recording purposes. A traditional echo chamber is covered in highly acoustically reflective surfaces. By using directional microphones pointed away from the speakers, echo capture is maximized. Some portions of the room can be moved to vary the room's decay time.
Delay is an audio signal processing technique that records an input signal to a storage medium and then plays it back after a period of time. When the delayed playback is mixed with the live audio, it creates an echo-like effect, whereby the original audio is heard followed by the delayed audio.

The most common device is a handheld, battery-operated device pressed against the skin under the mandible which produces vibrations to allow speech; [1] other variations include a device similar to the "talk box" electronic music device, which delivers the basis of the speech sound via a tube placed in the mouth.

Echo suppression and echo cancellation are methods used in telephony to improve voice quality by preventing echo from being created or removing it after it is already present. In addition to improving subjective audio quality, echo suppression increases the capacity achieved through silence suppression by preventing echo from traveling across a ...
Microphones placed in echo chambers with specially designed acoustic properties simulated the sound of live performances in different environments. In the mid to late 1940s, recording engineers and experimental musicians such as Les Paul began manipulating reel-to-reel recording tape to create echo effects and unusual, futuristic sounds.
Users may adjust the bass and treble levels on the output sound, the number of echo repeats, the length of each echo, and the ratio of the echo and reverb sounds. [1] The Space Echo has two microphone inputs, one instrument input, and one input for a mixer or PA. [1] The character of the delay sound changes as the tape wears with use. [2]
A mixer intended for a live venue or a recording studio typically has a range of input jacks, such as XLR connectors for microphones and the outputs from DI boxes, and 1/4" jacks for line level sources. A DJ mixer typically has RCA connector inputs for pre-recorded music being played back on turntables or CD players, and a single mic input.
