The notion of delay pertains to the use of a device (or digital equivalent therefore) allowing for the introduction of one or more precisely timed delays to a given input signal. This can be used for a variety of effects including, for example, the creation of the sensation of spatial depth.
A process in which a given input signal is looped and repeated, but with some period of time (delay) between the original sound and the repeated sound. This can be used for a variety of effects including, for example, the creation of the sensation of spatial depth. [EARS]
Where echo implies sound reflection in a given space, delay can be applied to a single sound channel.
