Acoustic Echo Cancellation for Wideband Audio
Speech processing is at last starting the transition to wider bandwidths, whose benefits include increased intelligibility and comprehension, and a more pleasing communication experience. High quality, full-duplex Acoustic Echo Cancellation (AEC) is an integral component of a hands-free speakerphone communication system because it allows participants to converse in a natural manner, as they would in person. Some high-end telepresence systems already achieve life-like communication, but they are computationally demanding and prohibitively expensive. The challenge is to develop a robust Acoustic Echo Canceller that processes full-band audio signals while maintaining low computational complexity and reasonable memory consumption for an affordable telepresence experience.
