Echo Cancellation
Technology that removes acoustic echo from audio in real-time.
Full Definition
Echo cancellation (AEC - Acoustic Echo Cancellation) is a signal processing technique that removes the acoustic echo that occurs when audio from speakers is picked up by microphones in the same space. Without echo cancellation, remote participants in video calls would hear their own voice reflected back with a delay. Modern AEC algorithms adapt to changing room acoustics and handle situations like full-duplex conversation where multiple people speak simultaneously.
