Binaural audio systems and methods

1. A system for delivery of binaural audio to a consumer comprising:

a computing device comprising at least one processor;

a non-transitory computer readable medium, having stored thereon, instructions that when executed by the computing device, cause the computing device to perform operations for delivery of the binaural audio to the consumer through at least one consumer device, wherein at least some of the operations occur within the at least one consumer device, the operations comprising:

enabling a delivery server to associate the at least one consumer device with at least one binaural audio file associated with at least a portion of an event attended by the consumer;

enabling the at least one consumer device to retrieve and download at least a portion of the at least one binaural audio file from the delivery server;

receiving, at the at least one consumer device, synchronization information associated with at least a portion of the event and the at least one binaural audio file; and

processing the at least one binaural audio file and delivering audio through an audio emitting device coupled to the at least one consumer device, wherein the delivered audio is synchronized with at least a portion of the event.

2. The system of claim 1 , wherein at least some of the operations cause the delivery server to access or record at least a portion of a live or previously recorded audio file associated with the event.

3. The system of claim 2 , wherein at least some of the operations cause the delivery server to process or convert at least a portion of the audio file to the at least one binaural audio file.

4. The system of claim 1 , wherein the at least one binaural audio file is delivered to the at least one consumer device prior to the event.

5. The system of claim 1 , wherein at least a portion of the at least one binaural audio file is delivered to the at least one consumer device during the event.

6. The system of claim 1 , wherein the synchronizing is accomplished via an audio sync signal emitted from loudspeakers in a venue for the event.

7. The system of claim 6 , wherein the audio sync signal encodes a series of tones representing an audio offset value, the series of tones comprising different frequencies representing consecutive identical digits in the audio offset value.

8. The system of claim 6 , further comprising re-synchronizing of the delivered audio while the event is in progress.

9. The system of claim 1 , wherein the synchronization information comprises audio information having a frequency above about 17.9 kHz.

10. The system of claim 1 , wherein the event is a motion picture.

11. The system of claim 10 , wherein the operations cause the at least one consumer device to download an audio track for the motion picture, the audio track encoded with binaural audio information.

12. The system of claim 11 , wherein the at least one consumer device comprises a mobile computing device.

13. The system of claim 1 , wherein the synchronization information is received by at least one microphone of the at least one consumer device or associated device associated or coupled to the at least one consumer device.

14. A system for delivery of binaural audio to consumer comprising:

a computing device comprising at least one processor;

a non-transitory computer readable medium, having stored thereon, instructions that when executed by the computing device, cause the computing device to perform operations wherein at least some of the operations occur within at least one consumer device, the operations comprising:

causing a delivery server to access or record at least a portion of a live or previously recorded audio file associated with an event, and processing or converting at least a portion of the audio file to least one binaural audio file;

enabling a delivery server to associate the at least one consumer device with the at least one binaural audio file associated with at least a portion of the event;

enabling the at least one consumer device to retrieve and download at least a portion of the at least one binaural audio file from the delivery server;

during the event, receiving at the at least one consumer device, at least one audio sync signal, the at least one audio sync signal associated with at least a portion of the event and the at least one binaural audio file; and

processing the at least one binaural audio file and delivering audio through an audio emitting device coupled to the at least one consumer device, wherein the delivered audio is synchronized with at least a portion of the event.

15. The system of claim 14 , wherein at least a portion of the at least one binaural audio file is delivered to the at least one consumer device during the event.

16. The system of claim 14 , wherein the at least one binaural audio file is delivered to the at least one consumer device prior to the event.

17. The system of claim 14 , wherein the audio sync signal emitted from loudspeakers of the event.

18. The system of claim 14 , wherein the audio sync signal encodes a series of tones representing an audio offset value, the series of tones comprising different frequencies representing consecutive identical digits in the audio offset value.

19. The system of claim 18 , further comprising re-synchronizing of the delivered audio while the event is in progress.

20. The system of claim 14 , wherein the audio sync signal is received by at least one microphone of the at least one consumer device or associated device associated or coupled to the at least one consumer device.
