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 ...
Audio signal processing is the electronic manipulation of audio signals using analog and digital signal processing. It is done for a variety of reasons, including: to enhance a sound, e.g. by applying an audio effect such as reverberation; to remove unwanted noises from a signal, e.g. echo cancellation in internet voice calls;
The process begins with background noise picked by a microphone getting amplified by a speaker in that same device. 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 waves combine to form a new wave, in a process called interference, and effectively cancel each other out – an effect which is called destructive interference.
