Abstract

Certain embodiments of the invention may include systems, methods, and apparatus for recording three dimensional audio. According to an example embodiment of the invention, the method may include orienting a three-dimensional (3-D) microphone with respect to a predetermined spatial direction, selectively receiving sounds from one or more directions corresponding to directional receiving elements, recording the selectively received sounds in a 3-D recorder having a plurality of recording channels, recording time code in at least one channel of the 3-D recorder; and mapping the recorded channels to a plurality of output channels.

Claims

1. A method for recording multi-dimensional audio, the method comprising:

orienting a three-dimensional (3-D) microphone with respect to a predetermined spatial direction;

selectively receiving sounds from one or more directions corresponding to directional receiving elements;

recording the selectively received sounds in a 3-D recorder having a plurality of recording channels;

recording time code in at least one channel of the 3-D recorder; and

mapping the recorded channels to a plurality of output channels, wherein the mapping comprises defining a plurality of sub-regions oriented on at least three vertical levels, each of the vertical levels comprising a substantially horizontal plane in a listening environment, and sounds are customized for each of the sub-regions.

2. The method of claim 1, wherein recording the selectively received sounds comprises recording signals from each of the directional receiving element in separate recording channels.

3. The method of claim 1, wherein orienting the 3-D microphone comprises orienting three or more directional receiving elements with respect to a predetermined spatial direction.

4. The method of claim 1, wherein recording time code in at least one channel of the 3-D recorder comprises recording time code associated with at least one video camera.

5. The method of claim 1, wherein mapping the recorded channels comprises directing recorded channels to output paths corresponding to a predetermined speaker layout.

6. The method of claim 1, wherein mapping the recorded channels comprises directing recorded channels to output paths corresponding to six speakers.

7. The method of claim 1, wherein mapping the recorded channels comprises directing recorded channels to output channels corresponding to a relative position of an object within a video frame.

8. A system for recording multi-dimensional audio and video, the system comprising:

at least one video camera;

a three-dimensional (3-D) microphone comprising a plurality of directional receiving elements, the 3-D microphone oriented with respect to a predetermined spatial direction associated with the video camera;

a 3-D recorder configured to selectively receive sound information from the 3-D microphone, and further configured to;

record the selectively received sound information in channels corresponding to the plurality of directional receiving elements;

record time code; and

map the recorded channels to a plurality of output channels, wherein a plurality of sub-regions is defined oriented on at least three vertical levels, each of the vertical levels comprising a substantially horizontal plane in a listening environment, and sound information is customized for each of the sub-regions.

9. The system of claim 8, wherein the 3-D microphone comprises four or more directional receiving elements.

10. The system of claim 8, wherein the 3-D recorder is further configured to record time code associated with the at least one video camera.

11. The system of claim 8, wherein the 3-D recorder is further configured to direct recorded channels to output paths corresponding to a predetermined speaker layout.

12. The system of claim 8, wherein the 3-D recorder is further configured to direct recorded channels to output paths corresponding to six speakers.

13. The system of claim 8, wherein the 3-D recorder is further configured to direct recorded channels to output channels corresponding to a relative position of an object within a video frame associated with the at least one video camera.

14. The system of claim 8, comprising two video cameras, wherein the two video cameras are operable to provide parallax information for mapping the recorded channels to a plurality of output channels.

15. An apparatus for recording multi-dimensional audio, the apparatus comprising:

a three-dimensional (3-D) microphone comprising a plurality of directional receiving elements, the 3-D microphone oriented with respect to a predetermined spatial direction;

a 3-D recorder configured to selectively receive sound information from the 3-D microphone, and further configured to;

record the selectively received sound information in channels corresponding to the plurality of directional receiving elements;

record time code; and

map the recorded channels to a plurality of output channels, wherein a plurality of sub-regions is defined oriented on at least three vertical levels, each of the vertical levels comprising a substantially horizontal plane in a listening environment, and sound information is customized for each of the sub-regions.

16. The apparatus of claim 15, wherein the 3-D microphone comprises four or more directional receiving elements.

17. The apparatus of claim 15, wherein the 3-D recorder is further configured to record time code associated with at least one video camera.

18. The apparatus of claim 15, wherein the 3-D recorder is further configured to direct recorded channels to output paths corresponding to a predetermined speaker layout.

19. The apparatus of claim 15, wherein the 3-D recorder is further configured to direct recorded channels to output paths corresponding to six speakers.

20. The apparatus of claim 15, wherein the 3-D recorder is further configured to direct recorded channels to output channels corresponding to a relative position of an object within a video frame.
