Title:

DEVICE AND METHOD FOR PROCESSING INTERNAL CHANNEL FOR LOW COMPLEXITY FORMAT CONVERSION

Document Type and Number:

WIPO Patent Application WO/2016/204583

Kind Code:

A1

Abstract:

A method for processing an audio signal, according to an embodiment of the present invention for achieving the technical objectives, comprises the steps of: receiving a signal to which internal channel gains (ICGs) have been pre-applied and which is for one channel pair element (CPE); if a reproduction channel configuration is not stereo, obtaining inverse internal channel gains (ICGs) for the CPE on the basis of rendering parameters in correspondence with MPS212 output channels defined in a format converter and MPS212 parameters; and generating output signals on the basis of the received signal for one CPE and the obtained inverse internal channel gains.
