Method and Apparatus for Decoding an Audio Signal |
摘要 |
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. |

1. A method for decoding an audio signal, the method comprising:
receiving the audio signal; demultiplexing the audio signal to core codec signal and spatial information, wherein the core codec signal is made by downmixing multi-channel signals and the spatial information is extracted when the downmixing is performed at an encoding device; decoding the core codec signal to output a decoded downmix signal; generating surround converting information by applying HRTF (Head-Related Transfer Function) parameters to the spatial information; and generating a pseudo-surround signal for an surround effect in a rendering domain by applying the surround converting information to the decoded downmix signal. |
