When certain devices, particularly mobile devices, or devices with integrated input and output devices, are being used, there's a chance that the input device will pick up on the audio from the output device. Vivox includes Acoustic Echo Cancellation (AEC), which helps to prevent this situation from occurring. While devices will often have their own hardware acoustic echo cancellation, Vivox's software Acoustic Echo Cancellation can be further enabled using the

VivoxService.Instance.EnableAcousticEchoCancellation()

method, and can be disabled using the

VivoxService.Instance.DisableAcousticEchoCancellation()

. This provides a second level of AEC on top of the platform’s AEC, if the device has AEC already, or it becomes the only layer of AEC if the device doesn’t have its own AEC. Often, platform AEC will only activate in certain scenarios while the Vivox AEC ensures that at least one form of AEC will activate in most circumstances.
