Apparatus for playing and producing realistic object audio

1. An apparatus for playing realistic object audio, the apparatus comprising:

a deformatter unit individually separating scene description (SD) compression data and object audio compression data from inputted audio files;

an SD decoding unit decoding the SD compression data to restore SD information;

an object audio decoding unit decoding the object audio compression data to restore object audio signals which are respective audio signals of a plurality of objects;

an object audio effect unit adding an audio effect for each object to the object audio signals according to SD information for each object corresponding to the object audio signals among the restored SD information to produce a realistic object audio signal corresponding to each of the object audio signals;

an audio mixing unit synthesizing each of the realistic object audio signals into at least one sound;

wherein the audio mixing unit further receives a user object audio signal which is not included in the inputted audio files and synthesizes the received user object audio signal into the at least one sound.

2. The apparatus of claim 1 , further comprising:

a user SD inputting unit receiving user SD information,

wherein the object audio effect unit adds the audio effect for each object to the object audio signals according to the SD information for each object corresponding to the object audio signals among the received user SD information to produce the realistic object audio signal.

3. The apparatus of claim 1 , further comprising:

an integrated audio effect unit adding an integrated audio effect to the at least one sound produced by the audio mixing unit.

4. The apparatus of claim 3 , wherein the integrated audio effect unit receives the restored SD information from the SD decoding unit to add the integrated audio effect to the at least one sound produced by the audio mixing unit according to the restored SD information.

5. The apparatus of claim 3 , further comprising:

a user object producing unit adding the user object audio signal according to user input and storing the user object audio signal which is an audio signal of the added user object audio signal.

6. The apparatus of claim 1 , wherein the SD information for each object includes at least one of information regarding the number of audios for each object, name information of audio for each object, type information of audio for each object, effect information of audio for each object, effect application time information of audio for each object, volume information of audio for each object, angle and distance information of audio for each object, angle and distance information for an externalization effect of audio for each object, 3D effect information of audio for each object and parameter information for the 3D effect information, background information of audio for each object, application start time information of audio for each object, application termination time information of audio for each object, playing-related time information of audio for each object, and parameter information of audio for each object.

7. The apparatus of claim 1 , wherein the deformatter unit individually separates the scene description (SD) compression data including conference SD information regarding a conference scene and the object audio compression data including voice signals of a plurality of conference participants from the inputted audio file.

8. The apparatus of claim 7 , wherein the object audio effect unit adds a conference audio effect to the voice signals of the plurality of conference participants according to the conference SD information to produce the realistic object audio signal.

9. An apparatus for playing realistic object audio, the apparatus comprising:

an object audio effect unit receiving scene description (SD) information and adding an audio effect for each object to object audio signals according to SD information for each object corresponding to each of the object audio signals in the received SD information to produce a realistic object audio signal corresponding to each of the object audio signals;

an audio mixing unit synthesizing each of the realistic object audio signals into at least one sound; and

a user object producing unit adding object audio according to user input and storing a user object audio signal which is an audio signal of the added object audio,

wherein the audio mixing unit further receives the user object audio signal to synthesize the received user object audio signal into the at least one sound.
