Release Information
The Acoustic Echo Cancellation/Removal (AER) removes or minimizes acoustic echo that is
generated by the coupling between the speaker and the microphone of a phone or similar device, particularly in hands-free mode. The primary purposes of the AER are:- Canceling echo so that it is not perceptible.
- Enabling full duplex operation.
- Controlling nonlinear distortion that is common at high speaker volumes.
- Suppressing near-end noise without affecting speech quality.
- Enabling phone manufacturers to achieve the required transmission characteristics of their phones as specified by various standards.
