Echo cancelers are sometimes as simple as devices that attenuate the far-end received signal, but these are not particularly satisfactory. Most modern echo cancelers measure the round-trip delay and construct adaptive filters that mimic that delay, subtracting the originated signal from the returned signal. Alango Acoustic Echo Cancellation (AEC) technology was designed to enable high quality, full duplex communication in mobile phones, hands-free car kits, speakerphones and other types of voice terminals. These devices are characterized by several aspects making development of AEC technology a real challenge: Echo cancellation is a simple concept–a voice processing engine analyses an incoming voice stream, and simultaneously monitors the return voice stream prior to transmission.
