An exemplary method for controlling audio data being communicated between a plurality of users over a packet based network comprises steps of combining a plurality of audio data streams into a single master stream, receiving at least one volume value for at least one of the plurality of audio data streams from each of the plurality of users, and creating a second or decompositor stream for each of the plurality of users using the at least one volume value from said each of the plurality of users. The exemplary method further includes steps of creating a volume adjusted master stream for each of the plurality of users by modifying the master stream with the decompositor stream for said each of the plurality of users.
