Systems and methods for computer and voice conference audio transmission during conference call via VoIP device

摘要

A new approach is proposed that contemplates systems and methods to support canceling audio streams leaked from a speaker to a microphone so that a clean audio stream of a presenter or viewer speaking at a conference call is transmitted. Here, the audio streams being canceled includes the computer audio stream of an application being run or a material being presented online during a web conference and/or the audio stream received from the rest of the group of participants at the conference call. The computer audio stream is then transmitted in addition to the presenter or viewer audio stream, and separate from any other audio stream captured by the hosting device during the conference call.

主权项

1. A system, comprising:
processing hardware; a host associated with a viewer; a computer audio engine of the host, which in operation, captures and outputs, using the processing hardware and via a voice conferencing bridge, a computer audio stream of an application or a presentation material to a voice audio engine; a sound mixing component of the host, which in operation, captures and outputs a mix of the computer audio stream and a conference audio stream from the voice audio engine to a speaker, wherein the computer audio engine is coupled to one or more sound capturing devices of the host and invokes application programming interfaces (APIs) to communicate with the one or more sound capturing devices; said voice audio engine running on the host, which in operation, transmits, without accessing the voice conferencing bridge, a clean viewer audio stream to the voice conference bridge hosting the conference call by cancelling, from an output of the sound mixing component, audio from participants in the conference different from the viewer.
