1. A method comprising:
- detecting a general listening zone comprising the audibly detectable areas surrounding a microphone array;
detecting an initial listening zone within the general listening zone, wherein the general listening zone comprises audibly detectable areas outside of the initial listening zone;
capturing an initial sound emanating from a sound source through the microphone array based on the initial listening zone wherein the initial sound includes sounds within the initial listening zone;
detecting an adjustment event, wherein the adjustment event comprises a change in a position of the sound source;
adjusting the initial listening zone and forming an adjusted listening zone in response to detecting the adjustment event; and
capturing an adjusted sound emanating from the sound source through the microphone array based on the adjusted listening zone wherein the adjusted sound includes sounds within the adjusted listening zone.

15. A method comprising:
-
detecting a sound field covered by a microphone array; defining a plurality of listening zones wherein each listening zone represents a portion of the sound field; designating a selected listening zone from the plurality of listening zones; and storing the selected listening zone within a profile; capturing sounds within the selected listening zone; detecting an adjustment event comprising a change in a position of a sound source; and capturing sounds from another one of the plurality of listening zones instead of the selected listening zone in response to detecting the adjustment event. - View Dependent Claims (16, 17)

18. A system, comprising:
-
an area detection module configured for detecting a listening zone wherein the listening zone is to be monitored for sounds emanating from a sound source by a microphone array that also detects sounds from outside the listening zone; a storage module configured for storing sounds from the listening zone; an area adjustment module configured for detecting an adjustment event and adjusting the listening zone to form an adjusted listening zone in response to detecting the adjustment event, wherein the adjustment event comprises a change in a position of the sound source; and a sound detection module configured for detecting sounds emanating from the sound source originating from the listening zone and the adjusted listening zone. - View Dependent Claims (19, 20)

21. A computer-readable medium having computer executable instructions for performing a method comprising:
-
detecting a general listening zone comprising the audibly detectable areas surrounding a microphone array; detecting an initial listening zone within the general listening zone, wherein the general listening zone comprises audibly detectable areas outside of the initial listening zone; capturing an initial sound emanating from a sound source through the microphone array based on the initial listening zone wherein the initial sound includes sounds within the initial listening zone; detecting an adjustment event, wherein the adjustment event comprises a change in a position of the sound source; adjusting the initial listening zone and forming an adjusted listening zone in response to detecting the adjustment event; and capturing an adjusted sound emanating from the sound source through the microphone array based on the adjusted listening zone wherein the adjusted sound includes sounds within the adjusted listening zone.
