Abstract: An apparatus for processing an audio signal and method thereof, the method including receiving a downmix signal including at least one normal object signal, and a bitstream including object information determined when the downmix signal is generated; extracting, from an extension part of the bitstream, an extension type identifier indicating whether the downmix signal further includes a multi-channel object signal; generating spatial information using the object information and mix information when mode information indicates that the multi-channel object signal is to be suppressed and the extension type identifier indicates that the downmix signal further includes the multi-channel object signal; and transmitting spatial information. The mix information is to control an object position or an object level of the at least one normal object signal.

Abstract: An apparatus for processing an audio signal and method thereof are disclosed. The present invention includes receiving a downmix signal and side information; extracting control restriction information from the side information; receiving control information for controlling gain or panning at least one object signal; generating at least one of first multi-channel information and first downmix processing information based on the control information and object information, without using the control restriction information; and, generating an output signal by applying the at least one of the first multichannel information and the first downmix processing information to the downmix signal, wherein the control restriction information relates to a parameter indicating limiting degree of the control information.

The spatial information is determined when a multi-channel source signal is downmixed into the multi-channel object signal. The mix information is to control an object position or an object level of the at least one normal object signal.
