23 * <p>Acoustic Echo Canceler (AEC) is an audio pre-processor which removes the contribution of the
25 * <p>AEC is used by voice communication applications (voice chat, video conferencing, SIP calls)
27 * is highly disturbing. AEC is often used in conjunction with noise suppression (NS).
28 * <p>An application creates an AcousticEchoCanceler object to instantiate and control an AEC
34 * <p>On some devices, an AEC can be inserted by default in the capture path by the platform
36 * call AcousticEchoCanceler.getEnable() after creating the AEC to check the default AEC activation
59 * @return AcousticEchoCanceler created or null if the device does not implement AEC.
