1. A method for processing an audio signal performed by an audio coding system, comprising:
- receiving a downmix signal comprising at least one object signal and at least one channel signal;
receiving object information determined when the downmix signal is generated;
receiving first multi-channel information;
receiving mix information including mode information indicating whether the first multi-channel information is applied to the processed downmix;
processing the downmix signal using the object information and the mix information; and
,generating second multi-channel information using the object information and the mix information, according to the mode information;
transmitting one of the first multi-channel information and the second multi-channel information according to the mode information.
