Recorded using 3d sound technology.

Field recording is the term used for an audio recording produced outside of a recording studio. The recording is typically recorded in the same channel format as the desired result, for instance, stereo recording equipment will yield a stereo product. This is in contrast to a multitrack remote recording which captures many microphones on multiple channels to be creatively modified, augmented and mixed down to a specific consumer format.

Field recording of natural sounds, also called phonography, was originally developed as a documentary adjunct to research work in the field and foley work for film. With the introduction of high-quality portable recording equipment, it has subsequently become an evocative artform in itself.
