Abstract
A method, computer program product, and computing system for receiving a signal from each microphone of a plurality of microphones, thus defining a plurality of signals. One or more inter-microphone gain-based augmentations may be performed on the plurality of signals, thus defining one or more inter-microphone gain-augmented signals.
Claims17
A computer-implemented method, executed on a computing device, comprising:
- receiving a signal from each microphone of a plurality of microphones, thus defining a plurality of signals;
- and
- performing one or more inter-microphone gain-based augmentations on the plurality of signals, thus defining one or more inter-microphone gain-augmented signals, wherein performing the one or more inter-microphone gain-based augmentations on the plurality of signals includes applying a gain level from a plurality of gain levels to the signal from each microphone, and wherein the plurality of gain levels is based upon a maximum and minimum gain introduced by each microphone relative to the plurality of microphones.
A computer program product residing on a non-transitory computer readable medium having a plurality of instructions stored thereon which, when executed by a processor, cause the processor to perform operations comprising:
- receiving a signal from each microphone of a plurality of microphones, thus defining a plurality of signals;
- and
- performing one or more inter-microphone gain-based augmentations on the plurality of signals, thus defining one or more inter-microphone gain-augmented signals, wherein performing the one or more inter-microphone gain-based augmentations on the plurality of signals includes applying a gain level from a plurality of gain levels to the signal from each microphone, and wherein the plurality of gain levels is based upon a maximum and minimum gain introduced by each microphone relative to the plurality of microphones.
A computing system comprising:
- a memory;
- and
- a processor configured to receive a signal from each microphone of a plurality of microphones, thus defining a plurality of signals, and wherein the processor is further configured to perform one or more inter-microphone gain-based augmentations on the plurality of signals, thus defining one or more inter-microphone gain-augmented signals, wherein performing the one or more inter-microphone gain-based augmentations on the plurality of signals includes applying a gain level from a plurality of gain levels to the signal from each microphone, and wherein the plurality of gain levels is based upon a maximum and minimum gain introduced by each microphone relative to the plurality of microphones.
