Stereophonic sound generating method and apparatus using multi-rendering scheme and stereophonic sound reproducing method and apparatus using multi-rendering scheme

1. A stereophonic sound reproducing method performed by a stereophonic sound reproducing apparatus, the method comprising:

receiving a channel sound signal based on a channel, an object sound signal based on an object, and metadata;

determining a rendering scheme based on a characteristic of the object sound signal;

reproducing the channel sound signal based on a preset rendering scheme; and

reproducing the object sound signal based on the metadata including the determined rendering scheme.

2. The stereophonic sound reproducing method of claim 1 , wherein the determined rendering scheme is changed on a time-by-time basis while the object sound signal is reproduced.

3. The stereophonic sound reproducing method of claim 1 , wherein the reproducing comprises compensating for a latency due to a difference in rendering scheme of the object sound signal.

4. The stereophonic sound reproducing method of claim 1 , wherein the reproducing comprises correcting a sound tone change and a sound volume change due to a difference in rendering scheme of the object sound signal.

5. The stereophonic sound reproducing method of claim 1 , wherein the preset rendering scheme of the channel sound signal includes a channel format for reproducing the channel sound signal, and the channel format is converted based on a reproduction environment.

6. A stereophonic sound generating method performed by a stereophonic sound generating apparatus, the method comprising:

identifying a channel sound signal based on a channel and an object sound signal based on an object;

determining a rendering scheme based on a characteristic of the identified object sound signal; and

generating metadata including the determined rendering scheme.

7. The stereophonic sound generating method of claim 6 , wherein the determined rendering scheme is changed on a time-by-time basis while the object sound signal is reproduced.

8. The stereophonic sound generating method of claim 7 , wherein the determined rendering scheme is changed based on a movement of an object corresponding to a target of the object sound signal.

9. A stereophonic sound reproducing apparatus comprising:

a processor configured to:

receive a channel sound signal based on a channel, an object sound signal based on an object, and metadata;

determine a rendering scheme based on a characteristic of the object sound signal;

reproduce the channel sound signal based on a preset rendering scheme; and

reproduce the object sound signal based on the metadata including the determined rendering scheme.

10. The stereophonic sound reproducing apparatus of claim 9 , wherein the processor is configured to change the determined rendering scheme on a time-by-time basis while the object sound signal is reproduced.

11. The stereophonic sound reproducing apparatus of claim 9 , wherein in response to reproducing the object sound signal, the processor is configured to compensate for a latency due to a difference in rendering scheme of the object sound signal.

12. The stereophonic sound reproducing apparatus of claim 9 , wherein when reproducing the object sound signal, the processor is configured to correct a sound tone change and a sound volume change due to a difference in rendering scheme of the object sound signal.

13. The stereophonic sound reproducing apparatus of claim 9 , wherein the processor is configured to perform conversion, based on a reproduction environment, on a channel format included in the preset rendering scheme of the channel sound signal.
