Processing the audio data

The KinectAudioSource class not only helps to capture the audio data from the sensors but also offers to take control over many aspects of audio data processing by interacting with the underlying DMO.

Echo cancellation

Echo cancellation helps to increase the sound quality. The Acoustic Echo Cancellation (AEC) component within the audio-processing pipeline is responsible for removing the echoes that we are sending to the microphone. To make the AEC work, you need to set the EchoCancellationMode property of kinectAudioSource.

EchoCancellationMode uses a set of enumeration values to set the type of echo cancellation as listed in the following table:

Name	Description
CancellationOnly	With the value of CancellationOnly, the audio DMO will perform only cancellation of acoustic echo.
CancellationAndSuppression	This enables the cancellation of echo as we perform the echo suppression using AES (Acoustic Echo Suppression ).
None	No echo cancellation will be performed...
