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 an extension type identifier indicating whether the downmix signal further includes a multi-channel object signal, from an extension part of the bitstream; extracting spatial information from the bitstream when the extension type identifier indicates that the downmix signal further includes the multi-channel object signal; and transmitting spatial information when mode information indicates that the least one normal object signal is to be suppressed. 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.

Abstract: Method and apparatus for processing audio signals are provided. The method for decoding an audio signal includes extracting a downmix signal and spatial information from a received audio signal, generating surround converting information using the spatial information and rendering the downmix signal to generate a pseudo-surround signal in a previously set rendering domain, using the surround converting information. The apparatus for decoding an audio signal includes a demultiplexing part extracting a downmix signal and spatial information from a received audio signal, an information converting part generating surround converting information using the spatial information and a pseudo-surround generating part rendering the downmix signal to generate a pseudo-surround signal in a previous set rendering domain, using the surround converting information.
