Abstract

A method for encoding three dimensional audio by a wireless communication device is disclosed. The wireless communication device detects an indication of a plurality of localizable audio sources. The wireless communication device also records a plurality of audio signals associated with the plurality of localizable audio sources. The wireless communication device also encodes the plurality of audio signals.

Claims

1. A method performed by a wireless communication device, comprising:

determining an energy profile of a plurality of audio signals;

displaying the energy profiles of each of the plurality of audio signals;

detecting an input that selects an energy profile;

associating a codec with the input; and

increasing bit allocation to the codec used to compress audio signals based on the input.

2. The method of claim 1, further comprising transmitting the packet over the air.

3. The method of claim 1, further comprising transmitting a channel identification.

4. The method of claim 1, wherein compression of the audio signals results in four packets being transmitted over the air.

5. The method of claim 1, wherein displaying the energy profiles comprises displaying a first energy profile representing a front left audio signal and displaying a second energy profile representing a front right audio signal.

6. The method of claim 1, wherein displaying the energy profiles comprises displaying a first energy profile representing a back left audio signal and displaying a second energy profile representing a back right audio signal.

7. The method of claim 1, wherein the energy profiles are associated with a standard channel format surround sound system.

8. A wireless communication device, comprising:

a processor configured to;
