Abstract

In accordance with the principles of the present invention, an audio-conference bridging system and method are provided. The present invention discards the traditional notion of a single mixing function for a conference. Instead, the novel, flexible design of the present invention provides a separate mixing function for each participant in the conference. This new architecture is described generally herein as “EdgePoint mixing.” EdgePoint mixing overcomes limitations of traditional conferencing systems by providing each participant control over his/her conference experience. EdgePoint mixing also allows, when desired, the simulation of a “real-life” conference by permitting each participant to receive a distinctly mixed audio signal from the conference depending on the speaker'"'"'s “position” within a virtual conference world. The present invention also preferably accommodates participants of different qualities of service. Each participant, thus, is able to enjoy the highest-level conferencing experience that his/her own connection and equipment will permit.

Claims

1. A method for facilitating an audio conference, comprising the steps of:

generating an audio-conference bridge operatively connecting participant stations in an audio conference, including at least a first participant station and a plurality of other participant stations, and adapted to receive incoming audio signals from the participant stations;

receiving first mixing control data for the first participant station, including data necessary to derive individual mixing parameters for at least two of the incoming audio signals from the other, participant stations;

receiving the incoming audio signals from a plurality of the participant stations;

setting a first set of audio conference mixing parameters based on at least the first mixing control data received for the first participant station;

mixing N of the incoming audio signals according to the first set of audio-conference mixing parameters to produce a first mixed, audio signal, where N is an integer greater than one; and

outputting the first mixed audio signal.
