Apparatus and method for frontal audio rendering in interaction with screen size

Abstract

Provided is an apparatus and method for frontal audio rendering in interaction with a screen size, the method including measuring playback environment information used to play back input content; and correcting an audio signal to be output based on the measured playback environment information and production environment information included in the input content.

What is claimed is: 
     
         1 . A method for processing an audio signal, the method comprising:
 determining whether a left speaker and a right speaker are located at both edge of a screen in a playback environment;   processing an audio signal based on the playback environment, when the left speaker and the right speaker are not located at both edge of a screen in the playback environment;   reproducing the processed audio signal,   wherein the audio signal is processed using (i) information with respect to the left speaker and the right speaker away from the screen and (ii) information for a horizontal axis length of the screen.   
     
     
         2 . The method of  claim 1 , wherein the audio signal is processed based on an angle between a user and the both edge of the screen in the playback environment. 
     
     
         3 . The method of  claim 1 , wherein the audio signal is processed based a size of the screen and an angle between the screen and a user. 
     
     
         4 . A method for processing an audio signal, the method comprising:
 identifying an audio signal for reproducing;   determining a playback environment for reproducing the audio signal;   processing the audio signal using the playback environment;   reproducing the processed audio signal,   wherein the audio signal is processed using (i) information of a screen in the playback environment, (ii) information of a left speaker or a right speaker disposed adjacent of the screen, (iii) information for relation between a user and the screen.   
     
     
         5 . The method of  claim 4 , wherein the audio signal is processed based on an angle between a user and the both edge of the screen in the playback environment. 
     
     
         6 . The method of  claim 4 , wherein the audio signal is processed based a size of the screen and an angle between the screen and a user. 
     
     
         7 . A device for processing an audio signal, the device comprising:
 one or more processor configured to:   determine whether a left speaker and a right speaker are located at both edge of a screen in a playback environment;   process an audio signal based on the playback environment, when the left speaker and the right speaker are not located at both edge of a screen in the playback environment;   reproduce the processed audio signal,   wherein the audio signal is processed using (i) information with respect to the left speaker and the right speaker away from the screen and (ii) information for a horizontal axis length of the screen.   
     
     
         8 . The device of  claim 7 , wherein the audio signal is processed based on an angle between a user and the both edge of the screen in the playback environment. 
     
     
         9 . The device of  claim 7 , wherein the audio signal is processed based a size of the screen and an angle between the screen and a user.
