Abstract

Conventional stereo audio recordings do not factor in natural ear spacing or “head shadow” of a user'"'"'s head and ears. The hinged computing devices disclosed herein incorporate a pair of microphones that approximate the user'"'"'s ear-to-ear spacing and orientation, as well as a physical structure that approximates the user'"'"'s head shadow. A resulting recording of the computing device'"'"'s environment may be conditioned and reproduced as a binaural stereo audio feed for selective playback to the user or other users.

Claims

1. A binaural computing device comprising:

a first device component including a first microphone;

a second device component including a second microphone, wherein the second device component is pivotally connected to the first device component, and wherein the first microphone and the second microphone are each positioned at a location of the binaural computing device distal from the pivotal connection; and

a binaural processing module to receive audio input from the first microphone and the second microphone and incorporate a head shadow corresponding to the binaural computing device to generate a binaural audio stream.

2. The binaural computing device of claim 1, further comprising:

an angular orientation sensor that detects an angle between the first device component and the second device component for generating the binaural audio stream.

3. The binaural computing device of claim 2, further comprising:

a hinge pivotally connecting the first device component to the second device component, wherein the angular orientation sensor detects an angular position of the hinge.

4. The binaural computing device of claim 1, further comprising:

a camera to capture one or more face characteristics for customizing the binaural audio stream for a user.

5. The binaural computing device of claim 1, wherein the first microphone and the second microphone are both forward-facing when the binaural computing device is oriented in a binaural audio recording position.

6. The binaural computing device of claim 1, wherein both of the first microphone and the second microphone are high-fidelity omnidirectional microphones.

7. The binaural computing device of claim 1, wherein one or both of the first device component and the second device component includes a touchscreen.

8. The binaural computing device of claim 1, wherein both of the first microphone and the second microphone are positioned 9 to 15 cm from the pivotal connection.

9. A method of using a computing device to create a binaural recording comprising:

pivoting a first device component with reference to a second device component to create an angle between the first device component and the second device component;

recording an audio stream from a first microphone within the first device component and a second microphone within the second device component onto the computing device; and

conditioning the recorded audio stream using a head shadow corresponding to the computing device to generate a binaural audio stream.

10. The method of claim 9, further comprising:

orienting the computing device such that a hinge pivotally connecting the first device component to the second device component points toward an audio source and both the first device component and the second device component angle away from the audio source, prior to recording the audio stream.

11. The method of claim 10, wherein orienting the computing device places the first device component 65 to 180 degrees from the second device component.

12. The method of claim 9, further comprising:

outputting the conditioned binaural audio stream to a playback device.

13. The method of claim 12, wherein the playback device is a set of headphones.

14. The method of claim 9, further comprising:

detecting the angle between the first device component and the second device component, wherein the conditioning the recorded audio stream includes adjusting the binaural audio stream based on the detected angle.

15. The method of claim 9, further comprising:

capturing one or more user face characteristics via a camera on the computing device, wherein the conditioning the recorded audio stream includes adjusting the binaural audio stream based on the captured user face characteristics.

16. A tangible computer-readable medium containing processor-executable instructions that, when executed by a processor, cause the processor to:

record an audio stream from a first microphone within a first device component and a second microphone within a second device component onto a binaural computing device, the first device component pivotally connected to the second device component; and

condition the recorded audio stream using a head shadow corresponding to the binaural computing device to generate a binaural audio stream.

17. The tangible computer-readable medium of claim 16, wherein the processor-executable instructions further cause the processor to:

output the conditioned binaural audio stream to a playback device.

18. The tangible computer-readable medium of claim 17, wherein the playback device is a set of headphones.

19. The tangible computer-readable medium of claim 16, wherein the processor-executable instructions further cause the processor to:

detect an angle between the first device component and the second device component, wherein the conditioning the recorded audio stream includes adjusting the binaural audio stream based on the detected angle.

20. The tangible computer-readable medium of claim 16, wherein the processor-executable instructions further cause the processor to:

capture one or more user face characteristics via a camera on the binaural computing device, wherein the conditioning the recorded audio stream includes adjusting the binaural audio stream based on the captured user face characteristics.
