Abstract
The present invention discloses a signal processing method, system and apparatus for 3-dimensional (3D) audio conferencing. The implementation is: a server obtains at least one audio stream relative to one terminal; the server allocates identifiers for the obtained at least one audio stream relative to the terminal; and the server combines the obtained at least one audio stream and the identifiers of the at least one audio stream and sends the combination to the terminal. With the technical solution of the present invention, the issue of excessive transmission channels required in the prior art is resolved and the terminal is capable of determining the sound image positions of other terminals freely.
