1. A system for transmitting neural data extracted from an electrical signal of a non-human mammal to a human, comprising: an electrode implantable into the animal auditory nerve, brainstem, or midbrain of the non-human mammal, configured to record the electrical signal of the non-human mammal, wherein the electrical signal is in the form of sequences of pulses or pulse trains encoding frequency information of the non-human mammal; a processing device electrically coupled with the electrode, configured to process the electrical signal and convert the processed electrical signal into a digital signal; a transmitting device electrically coupled with the processing device, configured to transmit the digital signal; and a receiving device electrically coupled with the transmitting device, configured to receive the transmitted digital signal, convert the received digital signal into a sensory output perceptible to the human, and apply the sensory output to the human.
