Abstract: Some embodiments provide an architecture (100) for establishing multi-participant audio conferences over a computer network. This architecture (100) has a central distributor (125) that receives audio signals (205, 210, 215) from one or more participants (110, 115, 120). The central distributor (125) mixes the received signals and transmits them back to participants (110,115,120). In some embodiments, the central distributor (125) eliminates echo by removing each participant's audio siganl from the mixed signal that the central distributor (125) sends to the particular participant.
