Echo removal is the process of removing echo and reverberation artifacts from audio signals. The reverberation is typically modeled as the convolution of a (sometimes time-varying) impulse response with a hypothetical clean input signal, where both the clean input signal (which is to be recovered) and the impulse response are unknown.
If the delay is slightly longer, around 50 milliseconds, humans cannot hear the echo as a distinct sound, but instead hear a chorus effect. [3] In the earlier days of telecommunications, echo suppression was used to reduce the objectionable nature of echos to human users. One person speaks while the other listens, and they speak back and forth.
This noise is audio feedback which is stored to later be cancelled; An adaptive filter uses an algorithm to maximize the amount of the stored audio feedback that can be cancelled; The adaptive filter is implemented in an acoustic device, and the repetition of this process is adaptive feedback cancellation
In audio signal processing, ringing can cause echoes to occur before and after transients, such as the impulsive sound from percussion instruments, such as cymbals (this is impulse ringing). The ( causal ) echo after the transient is not heard, because it is masked by the transient, an effect called temporal masking .
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.
