Abstract: A method and apparatus for outputting an audio signal corresponding to a user position are disclosed. The method includes receiving an audio signal and providing a decoding audio signal and decoded metadata, checking whether a user position is changed in an arbitrary space using user position information including a user position change indicator and user position change offset, when the user position is changed, providing modified metadata obtained by correcting the decoded metadata based on the user position change offset, and rendering the decoded audio signal using the modified metadata. Accordingly, it is possible to provide an audio sound image that is changed in response to change in user position in an arbitrary space, thereby providing more realistic audio output.
