Abstract

There is provided a system and method for playing a venue-specific object-based audio in a venue, the system comprising a memory, and a processor configured to receive an object-based audio including a plurality of audio components and create a venue-specific object-based audio based on a modification metadata by adjusting a level of at least one of the plurality of audio components of the object-based audio, the processor executing the object-based audio rendering software to render the venue-specific object-based audio in the venue.

Claims

1. A system for playing a venue-specific object-based audio in a venue, the system comprising:

a memory storing an audio enhancement software, a modification metadata, and an object-based audio rendering software; and

a processor executing the audio enhancement software to;

receive an object-based audio including a plurality of audio components; and

create the venue-specific object-based audio based on the modification metadata by adjusting a level of at least one of the plurality of audio components of the object-based audio;

the processor executing the object-based audio rendering software to;

render the venue-specific object-based audio in the venue;

wherein the modification metadata is based on one or more venue-specific measured parameters obtained by measuring one or more acoustic properties of the venue.

2. The system of claim 1, wherein the processor is further configured to:

transmit the venue-specific object-based audio to a plurality of loudspeakers in the venue.

3. The system of claim 1, wherein the plurality of audio components include a dialog component, a music component, and an effects component.

4. The system of claim 1, wherein creating the venue-specific object-based audio includes adjusting at least one of a surround-sound balance and an overhead balance of at least one of the plurality of audio components of the object-based audio based on the modification metadata.

5. The system of claim 1, wherein creating the venue-specific object-based audio includes adjusting a suhwoofer level of the object-based audio based on the modification metadata.

6. The system of claim 1, wherein the modification metadata includes static modifications.

7. The system of claim 1, wherein the modification metadata includes one of dynamic modifications and film-specific modifications.

8. The system of claim 1, wherein measuring the one or more acoustic properties of the venue comprises recording, using a microphone, a sound at one or more locations in the venue.

9. The system of claim 8, wherein the one or more acoustic properties of the venue include at least one of a reverberation time of the venue, a low-frequency reverberation time of the venue, and a resonance of the venue.

10. A method for playing a venue-specific object-based audio in a venue using an audio system including a memory storing a modification metadata and a processor, the method comprising:

receiving, using the processor, an object-based audio including a plurality of audio components;

creating, using the processor, the venue-specific object-based audio by adjusting a level of at least one of the plurality of audio components based on the modification metadata; and

rendering, using the processor, the venue-specific object-based audio in the venue;

wherein the modification metadata is based on one or more venue-specific measured parameters obtained by measuring one or more acoustic properties of the venue.

11. The method of claim 10, wherein the processor is further configured to:

transmit the modified audio to a plurality of loudspeakers in the venue.

12. The method of claim 10, wherein the plurality of audio components include a dialog component, a music component, and an effects component.

13. The method of claim 10, wherein creating the venue-specific object-based audio includes adjusting at least one of a surround-sound balance and an overhead balance of at least one of the plurality of audio components of the object-based audio based on the modification metadata.

14. The method of claim 10, wherein creating the venue-specific audio includes adjusting a subwoofer level of the object-based audio based on the modification metadata.

15. The method of claim 10, wherein the modification metadata includes static modifications.

16. The method of claim 10, wherein the modification metadata includes one of dynamic modifications and film-specific modifications.

17. The method of claim 10, wherein measuring the one or more acoustic properties of the venue comprises recording, using a microphone, a sound at one or more locations in the venue.

18. The method of claim 17, wherein the one or more acoustic properties of the venue include at least one of a reverberation time of the venue, a low-frequency reverberation time of the venue, and a resonance of the venue.
