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.
Delayed Auditory Feedback (DAF), also called delayed sidetone, is a type of altered auditory feedback that consists of extending the time between speech and auditory perception. [1] It can consist of a device that enables a user to speak into a microphone and then hear their voice in headphones a fraction of a second later.
It uses tape delay to create a delayed copy of an audio signal which is then played back at slightly varying speed controlled by an oscillator and combined with the original. The effect is intended to simulate the sound of the natural doubling of voices or instruments achieved by double tracking.
The effect of delayed auditory feedback (DAF) in reducing stuttering has been noted since the 1950s. [ 15 ] [ 16 ] A DAF user hears his or her voice in headphones, delayed a fraction of a second. Typical delays are in the 50 millisecond to 200 millisecond range. [ 2 ]
Solid-state flanging devices fall into two categories: analog and digital. The Eventide Instant Flanger from 1975 is an early example of a studio device that was able to successfully simulate tape flanging using bucket-brigades to create the audio delay. [13] The flanging effect in most newer digital flangers relies on DSP technology. Flanging ...
Latency refers to a short period of delay (usually measured in milliseconds) between when an audio signal enters a system, and when it emerges.Potential contributors to latency in an audio system include analog-to-digital conversion, buffering, digital signal processing, transmission time, digital-to-analog conversion, and the speed of sound in the transmission medium.

The precedence effect or law of the first wavefront is a binaural psychoacoustical effect concerning sound reflection and the perception of echoes.When two versions of the same sound presented are separated by a sufficiently short time delay (below the listener's echo threshold), listeners perceive a single auditory event; its perceived spatial location is dominated by the location of the ...
