Abstract

A communication device and method for adapting to audio accessories are provided. The communication device includes a memory; a first microphone, a connector for receiving data from an accessory device having a second microphone, and a processor interconnected with the memory, the microphone and the connector. The processor is configured to receive audio input and, when the audio input originated at the second microphone, to automatically apply equalization settings corresponding to the second microphone.

Claims

1. A communication device, comprising:

a memory;

a first microphone;

a connector for receiving data from an accessory device having a second microphone; and

a processor interconnected with the memory, the microphone and the connector, the processor configured to;

receive audio input;

when the audio input originated at the second microphone,

automatically apply equalization settings corresponding to the second microphone.

2. The communication device of claim 1, the processor further configured to:

when the audio input originated at the first microphone, determine a first frequency spectrum of the audio input; and

store the frequency spectrum in a voice profile in the memory.

3. The communication device of claim 2, the processor further configured to:

when the audio input originated at the second microphone, determine a second frequency spectrum of the audio input; and

generate the equalization settings by comparing the second frequency spectrum to the voice profile.

4. The communication device of claim 3, the processor further configured to:

store the equalization settings in the memory in an accessory profile corresponding to the second microphone.

5. The communication device of claim 3, wherein the equalization settings comprise at least one gain value corresponding to at least one frequency band;

the processor further configured to generate the equalization settings by selecting the at least one gain value based on the difference between an amplitude of the at least one frequency band in the first frequency spectrum and an amplitude of the at least one frequency band in the second frequency spectrum.

6. The communication device of claim 1, the processor further configured to:

when the audio input originated at the second microphone, retrieve the equalization settings from the memory in an accessory profile in corresponding to the second microphone.

7. The communication device of claim 1, the processor further configured to determine whether the audio input originated at the second microphone, prior to applying the equalization settings.

8. A method in a communication device having a processor, a memory, a first microphone and a connector, comprising:

receiving audio input at the processor;

determining whether the audio input originated at the first microphone or at a second microphone of an accessory device coupled to the processor via the connector; and

when the audio input originated at the second microphone, automatically applying equalization settings corresponding to the second microphone.

9. The method of claim 8, further comprising:

when the audio input originated at the first microphone, determining a first frequency spectrum of the audio input; and

storing the frequency spectrum in a voice profile in the memory.

10. The method of claim 9, further comprising:

when the audio input originated at the second microphone, determining a second frequency spectrum of the audio input; and

generating the equalization settings by comparing the second frequency spectrum to the voice profile.

11. The method of claim 10, further comprising:

storing the equalization settings in the memory in an accessory profile corresponding to the second microphone.

12. The method of claim 10, wherein the equalization settings comprise at least one gain value corresponding to at least one frequency band;

the method further comprising;

generating the equalization settings by selecting the at least one gain value based on the difference between an amplitude of the at least one frequency band in the first frequency spectrum and an amplitude of the at least one frequency band in the second frequency spectrum.

13. The method of claim 8, further comprising:

when the audio input originated at the second microphone, retrieving the equalization settings from the memory in an accessory profile in corresponding to the second microphone.

14. A non-transitory computer-readable medium storing a plurality of computer-readable instructions executable by a processor of a communication device having a memory, a first microphone and a connector coupled to the processor, for performing a method comprising:

receiving audio input at the processor;

determining whether the audio input originated at the first microphone or at a second microphone of an accessory device coupled to the processor via the connector; and

when the audio input originated at the second microphone, automatically applying equalization settings corresponding to the second microphone.

15. The non-transitory computer-readable medium of claim 14, the method further comprising:

when the audio input originated at the first microphone, determining a first frequency spectrum of the audio input; and

storing the frequency spectrum in a voice profile in the memory.

16. The non-transitory computer-readable medium of claim 15, the method further comprising:

when the audio input originated at the second microphone, determining a second frequency spectrum of the audio input; and

generating the equalization settings by comparing the second frequency spectrum to the voice profile.

17. The non-transitory computer-readable medium of claim 16, the method further comprising:

storing the equalization settings in the memory in an accessory profile corresponding to the second microphone.

18. The non-transitory computer-readable medium of claim 16, wherein the equalization settings comprise at least one gain value corresponding to at least one frequency band;

the method further comprising;

generating the equalization settings by selecting the at least one gain value based on the difference between an amplitude of the at least one frequency band in the first frequency spectrum and an amplitude of the at least one frequency band in the second frequency spectrum.

19. The non-transitory computer-readable medium of claim 14, the method further comprising:

when the audio input originated at the second microphone, retrieving the equalization settings from the memory in an accessory profile in corresponding to the second microphone.
