==Binaural recording==
{{Further|Binaural recording}}
Engineers make a technical distinction between "binaural" and "stereophonic" recording. Of these, [[binaural recording]] is analogous to [[Stereoscopy|stereoscopic photography]]. In binaural recording, a pair of microphones is put inside a [[kunstkopf|model of a human head]] that includes external ears and ear canals; each microphone is where the [[eardrum]] would be.  The recording is then played back through headphones, so that each channel is presented independently, without mixing or crosstalk. Thus, each of the listener's eardrums is driven with a replica of the auditory signal it would have experienced at the recording location. The result is an accurate duplication of the [[auditory spatiality]] that would have been experienced by the listener had he or she been in the same place as the model head. Because of the inconvenience of wearing headphones, true binaural recordings have remained laboratory and audiophile curiosities.  However "loudspeaker-binaural" listening is possible with [[Ambiophonics]].

Numerous early two-track-stereo reel-to-reel tapes as well as several experimental stereo disc formats of the early 1950s branded themselves as binaural, however they were merely different incarnations of the above-described stereo or two-track mono recording methods (lead vocal or instrument isolated on one channel and orchestra on the other sans lead.)
