A new approach is proposed that contemplates systems and methods to support canceling audio streams leaked from a speaker to a PSTN so that only the audio stream of a presenter or viewer speaking at a conference call is transmitted. Here, the audio streams being canceled includes the audio stream of an application being run or a material being presented online during a web conference. The voice audio stream of a presenter or viewer is then transmitted in addition to the computer audio stream, clean from any other audio stream of echoes or feedbacks captured by the hosting device during the conference call.
La présente invention concerne une nouvelle approche, qui envisage des procédés et des systèmes visant à prendre en charge l'annulation de flux audio fuyant d'un haut-parleur vers un téléphone rtpc de manière à ne transmettre que le flux audio d'un présentateur ou d'un spectateur s'exprimant lors d'une conférence téléphonique. Ici, les flux audio annulés comprennent le flux audio d'une application en cours d'exécution ou d'un matériel en cours de présentation en ligne, lors d'une conférence Web. Le flux audio vocal d'un présentateur ou d'un spectateur est ensuite transmis en plus du flux audio informatique, nettoyé de tout autre flux audio d'échos ou de rétroactions capturé par le dispositif d'accueil lors de la conférence téléphonique.
