Abstract
Media, methods, and systems are provided for audio rerouting to echo cancel audio in web browsers hosting video streams. Spoken audio from a presenter in a video stream may be received via a microphone on a presenter computing device using a first audio connection. Echo cancellation for the presenter may be enabled. Media audio from the presenter may be received originating from a second audio connection. In response to receiving the media audio, a loopback connection for the presenter may be created. In the loopback connection, the presenter may act as both the sender and receiver of the media audio. The loopback connection may have echo cancellation enabled and use the first audio connection. Once the loopback connection is created, the audio may be routed through the loopback connection. The audio may then be played out of an audio output device for the presenter with echo cancellation enabled.
