Method of setting an equalizer in an apparatus to reproduce a media file and apparatus thereof
A method and apparatus to reproduce a media file including reading mapping information from a predetermined position of the media file, searching for a sound field effect file of the media file by referring to the mapping information, and setting an equalizer of the audio data on the basis of the sound field effect file. A user can reproduce a media file by using an optimized equalizer of each media file even though the user himself does not set the equalizer. Also, since an equalizer setting of the reproducing apparatus can be applied to another reproducing apparatus, a user can enjoy listening to a media file in the other reproducing apparatus under the same reproducing conditions as those of the reproducing apparatus.
1. A method of reproducing a media file comprising audio data, the method comprising:
reading mapping information from the media file;
searching for sound field effect files of the media file by referring to the mapping information;
selecting a sound field effect file located by the searching unit, if the searching unit locates more than one sound effect file; and
setting an equalizer of the audio data on the basis of the selected sound field effect file.
2. The method of claim 1 , further comprising:
recording the mapping information in the predetermined position of the media file.
3. The method of claim 2 , further comprising:
extracting an equalizer setting while the media file or another media file is being reproduced; and
generating the sound field effect file by using the extracted equalizer setting.
4. The method of claim 1 , wherein the selecting comprises selecting the sound effect file based on input from a user.
5. The method of claim 1 , wherein the mapping information comprises information representing a position of the sound field effect file in a local directory of an apparatus to reproduce the media file.
6. The method of claim 1 , wherein the mapping information comprises a uniform resource locator (URL) of the sound field effect file.
7. A computer readable recording medium having embodied thereon a computer program to execute the method of claim 1 .
8. An apparatus to reproduce a media file comprising audio data, the apparatus comprising:
a mapping information reading unit to read mapping information from the media file;
a file searching unit to search for sound field effect files of the media file by referring to the mapping information;
a selecting unit to select a sound field effect file located by the searching unit, if the searching unit locates more than one sound effect file; and
an equalizer setting unit to set an equalizer setting of the audio data on the basis of the selected sound field effect file.
9. The apparatus of claim 8 , further comprising:
a mapping information recording unit to record the mapping information in the predetermined position of the media file.
10. The apparatus of claim 9 , further comprising:
an extracting unit to extract an equalizer setting while the media file or another media file is being reproduced; and
a file generating unit to generate the sound field effect file by using the extracted equalizer setting.
11. The apparatus of claim 8 , wherein the selecting unit selects the sound effect file based on input from a user.
12. The apparatus of claim 8 , wherein the mapping information comprises information representing a position of the sound field effect file in a local directory of the apparatus to reproduce the media file.
13. The apparatus of claim 8 , wherein the mapping information comprises a uniform resource locator (URL) of the sound field effect file.
