Abstract:
1. A method for processing audio signals using a Multipoint Control Unit (MCU) in communication with multiple terminals in a conference system, wherein the multiple terminals include more than one sending terminal and at least one receiving terminal, the method comprising: receiving, by the MCU, audio signals sent from the more than one sending terminal; determining, by the MCU, that a channel quantity of a first receiving terminal of the at least one receiving terminal is bigger than one, and that a channel quantity of a first sending terminal of the more than one sending terminal is different from the channel quantity of the first receiving terminal; processing, by the MCU, based on the determining, a first audio signal received from the first sending terminal based on location information assigned by the MCU to the first sending terminal, to obtain a processed audio signal capable of indicating a location represented by the location information at the first receiving terminal, wherein a channel quantity of the processed audio signal is the same as the channel quantity of the first receiving terminal; mixing, by the MCU, the processed audio signal and a second audio signal originated from a second sending terminal of the more than one sending terminal to obtain a mixed audio signal, wherein a channel quantity of the second audio signal is the same as the channel quantity of the first receiving terminal; encoding, by the MCU, the mixed audio signal; and sending, by the MCU, the encoded mixed audio signal to the first receiving terminal.
