5. The headset of claim 4 , wherein during the second mode the application is further configured to record the sound corresponding to voice communications between the headset wearer and the conversation participant in adjacent proximity to the headset wearer in the memory.
6. The headset of claim 4 , wherein during the second mode the application is further configured to transmit the sound corresponding to voice communications between the headset wearer and the conversation participant in adjacent proximity to the headset wearer to a remote device over the communications interface.
7. The headset of claim 4 , wherein the second set of signal processing parameters are further configured to normalize an audio level of a headset wearer speech and a conversation participant speech prior to recording or transmission.
8. The headset of claim 4 , wherein second set of signal processing parameters are configured to process the sound corresponding to voice communications between the headset wearer and the conversation participant in adjacent proximity to the headset wearer to isolate a headset wearer voice in a first channel and isolate a conversation participant voice in a second channel.
9. The headset of claim 1 , further comprising a sensor providing a sensor output, wherein the application is further configured to process the sensor output to determine a direction or a distance of a person associated with a voice in proximity to the headset wearer, wherein the application is further configured to utilize the direction or the distance in the second set of signal processing parameters.
10. The headset of claim 9 , wherein the sensor is a video camera, an infrared system, or an ultrasonic system.
11. The headset of claim 1 , wherein the application is further configured to switch between the first mode and the second mode responsive to a user action received at the user interface.
12. The headset of claim 1 , wherein the application is further configured to switch between the first mode and the second mode responsive to an instruction received from a remote device.
13. A method comprising:
operating a headset in a user selectable first mode comprising a telephony mode or a user selectable second mode comprising an interview mode of operation for selection when a headset wearer is in a face to face conversation with a conversation participant, the headset comprising a microphone array arranged to detect sound, the headset having both the user selectable first mode and the user selectable second mode;
receiving sound at the microphone array and converting the sound to an audio signal;
eliminating a voice of the conversation participant in the audio signal in the user selectable first mode comprising the telephony mode;
detecting and recording the voice of the conversation participant in the audio signal in the user selectable second mode comprising the interview mode.
14. The method of claim 13 , wherein detecting and recording the voice of the conversation participant in the audio signal in the user selectable second mode comprises utilizing a beam forming algorithm to isolate the voice in proximity to the headset wearer.
15. The method of claim 13 , wherein the user selectable first mode comprises telephony voice communications between the headset wearer and a voice call participant and the user selectable second mode comprises voice communications between the headset wearer and the conversation participant.
16. The method of claim 13 , further comprising transmitting the voice of the conversation participant in the user selectable second mode to a remote device.
17. The method of claim 13 , further comprising normalizing an audio level of a headset wearer speech and the voice of the conversation participant in the user selectable second mode.
18. The method of claim 13 , further comprising processing the audio signal to isolate a headset wearer voice in a first channel and isolate the voice of the conversation participant in a second channel in the user selectable second mode.
19. The method of claim 13 , further comprising switching between the user selectable first mode and the user selectable second mode responsive to a user action received at a headset user interface or responsive to an instruction received from a remote device.
20. One or more non-transitory computer-readable storage media having computer-executable instructions stored thereon which, when executed by one or more computers, cause the one more computers to perform operations comprising:
operating a headset in a first mode comprising a telephony mode or a second mode comprising an interview mode of operation for selection when a headset wearer is in a face to face conversation with a conversation participant, the headset comprising a microphone array arranged to detect sound and the headset having both the first mode and the second mode;
receiving sound at the microphone array and converting the sound to an audio signal;
