1. An apparatus for identifying a vocalization of a game animal, comprising:
an audio receiving device having a recording mode, the audio receiving device placed in an outdoor hunting location for receiving sound patterns during the recording mode in proximity to the audio receiving device and for converting the received sound patterns into a plurality of audio signals, the audio receiving device comprising two or more microphones configured to receive the sound patterns and a clock unit configured to enable the recording mode during a predetermined game activity period, the predetermined game activity period comprising a period of time during which the hunter is/will be absent from the outdoor hunting location and the game animal is likely to make a vocalization; a controller in communication with the audio receiving device; wherein the controller receives the plurality of audio signals from the audio receiving device: a band-pass filter connected to the controller; the band-pass filter initially filters the plurality of audio signals; a processing unit connected to the controller; the processing unit evaluates the plurality of audio signals and identifies which of the plurality of audio signals are the vocalization of the game animal; the clock unit connected to the controller for determining a present time for the vocalization of the game animal; a user interface connected to the controller for receiving instructions from a user; a location detector connected to the controller configured to determine a direction from which the vocalization of the game animal originates based upon a relative energy estimation of the sound patterns received by the microphones and a combination of a distance and a direction of the vocalization of the game animal; a storage unit connected to the controller to store the vocalization of the game animal, the time of the vocalization of the game animal, the distance of the vocalization of the game animal and the direction of the vocalization of the game animal; and a sound producing device connected to the controller and a pre-recorded sound recording of a sound from wildlife known to elicit the vocalization of the game animal stored in the storage unit connected to the controller, the sound producing device located proximate the outdoor hunting location and configured to play the pre-recorded sound recording of the sound from wildlife known to elicit the vocalization of the game animal at a plurality of timed or trigger-dependent intervals to the outdoor hunting location during the predetermined game activity period while the apparatus is in the recording mode for receiving the sound patterns. |
