Claim Text:
1. An apparatus for controlling rendering of audio signals, comprising: an SAC decoder for decoding an input audio signal, which is a down-mixed signal that is encoded in a Spatial Audio Coding (SAC) method, by using an SAC decoding method; and a spatial cue renderer for receiving spatial cue information and control information on rendering of the input audio signal and controlling the spatial cue information in a spatial cue domain based on the control information, wherein the control information includes audio scene information including output position and output level of an input audio signal, wherein the SAC decoder performs rendering onto the input audio signals based on a controlled spatial cue information controlled by the spatial cue rendering means, and wherein the spatial cue renderer extracts audio signal information from the from the spatial cue, adjusts the extracted audio signal information based on the control information, and creates the controlled spatial cue using the adjusted audio signal information.
