Abstract

A system and method for enhancing comprehensibility through spatialization may receive two or more audio signals each associated with one of two or more audio sources. A respective panning gain may be calculated for each of the two or more audio signals using a count of the total number of audio sources and a count of a total number of output channels. The respective panning gain may be calculated further responsive to audio source metadata associated with each of two or more audio sources. Each of the two or more audio signals may be gain adjusted responsive to the respective panning gain. Each of the two or more gain adjusted audio signals may be mixed to create two or more output channels wherein a reproduction of the output channels produces enhanced comprehensibility.

Claims (26)

1. A method for enhancing comprehensibility through spatialization comprising:

receiving two or more audio signals each associated with one of two or more audio sources;

calculating a respective panning gains for each of the two or more audio signals, respectively based on the total number of audio sources and the total number of output channels;

gain adjusting each of the two or more audio signals responsive to the respective panning gain; and

mixing each of the two or more gain adjusted audio signals to create two or more output channels wherein a reproduction of the output channels produces enhanced comprehensibility.

2. The method for enhancing comprehensibility through spatialization of claim 1 , further comprising receiving audio source metadata associated with each of the two or more audio sources.

3. The method for enhancing comprehensibility through spatialization of claim 2 , calculating the respective panning gains for each of the two or more audio signals, respectively, based on the audio source metadata associated with each of the two or more audio sources.

4. The method for enhancing comprehensibility through spatialization of claim 3 , where the audio source metadata comprises any one or more of audio source priority, audio source grouping, and audio source role assignment.

5. The method for enhancing comprehensibility through spatialization of claim 3 , where the audio source metadata comprises an Internet Protocol address.

6. The method for enhancing comprehensibility through spatialization of claim 3 , calculating the respective panning gain further responsive to a received near end panning control.

7. The method for enhancing comprehensibility through spatialization of claim 1 , further comprising reproducing the two or more output channels to create a sound field.

8. The method for enhancing comprehensibility through spatialization of claim 1 , where calculating the respective panning gain comprises a calculation to direct each of the two or more audio signals to separated positions in the sound field.

9. The method for enhancing comprehensibility through spatialization of claim 4 , where calculating the respective panning gain comprises a calculation to direct each of the two or more audio signals to a relative location in the two or more output channels responsive to the audio source meta data.

10. A system for enhancing comprehensibility through spatialization comprising:

two or more gain adjusters to receive audio signals associated with one of two or more audio sources;

a panning controller to calculate panning gains for each of the two or more audio signals, respectively, based on the total number of audio sources and the total number of output channels;

the two or more gain adjusters gain adjust each of the two or more audio signals responsive to the respective panning gain; and

two or more mixers to mix each of the two or more gain adjusted audio signals to create two or more output channels wherein a reproduction of the output channels produces enhanced comprehensibility.

11. The system for enhancing comprehensibility through spatialization of claim 10 , where the panning controller is configured to receive audio source metadata associated with each of two or more audio sources.

12. The system for enhancing comprehensibility through spatialization of claim 11 , where the panning controller calculates the panning gains for each of the two or more audio signals using the audio source metadata.

13. The system for enhancing comprehensibility through spatialization of claim 11 , where the panning roller calculates the panning gains for each of the two or more audio signals, respectively, based on audio source metadata designating any one or more of audio source priority, audio source grouping, and audio source role assignment.

14. The system for enhancing comprehensibility through spatialization of claim 13 , where the audio source metadata comprises an Internet Protocol address.

15. The system for enhancing comprehensibility through spatialization of claim 11 , there the panning controller is responsive to a received near end panning control.

16. The system for enhancing comprehensibility through spatialization of claim 10 , further comprising two or more audio transducers to reproduce the two or more output channels to create a sound field from the two or more output channels.

17. The system for enhancing comprehensibility through spatialization of claim 10 , where calculating the panning gains comprises a calculation to direct each of the two or more audio signals to separated positions in the sound field.

18. The system for enhancing comprehensibility through spatialization of claim 13 , where calculating the panning gains comprises a calculation to direct each of the two or more audio signals to a relative location in the two or more output channels responsive to the audio source meta data.
