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.
The secondary purpose of the AER is:
Enabling phone manufacturers to achieve the required transmission characteristics
of their phones as specified by various standards.
The deliverables in this release include a Windows or a Linux installation executable for
the supported processors. Each executable installs a component package repository,
a documentation directory, an Eclipse plugin directory and an expanded component
directory structure with all component libraries, header files and test examples.
