Indeed it may be surprising that "stereo sound" (and later analogues like "stereo vision") have nothing, etymologically, to do with having two channels; it was essentially introduced as a marketing term referring to the more "solid" or tangible sensory quality compared to single-channel sound.
- jacobsimon 4y agoI think stereo vision predates the usage in sound, and refers more to the 3D depth perception of shapes that it allows. Stereography was invented sometime in the mid 1800s [1]. Stereo sound similarly is meant to give a more realistic perception of sound in space compared to mono. 1. https://www.smithsonianmag.com/innovation/sterographs-original-virtual-reality-180964771/ https://www.smithsonianmag.com/innovation/sterographs-origin...
- Sharlin 4y agoOops, very good point. I forgot that stereograms were a thing already in the 1800s (being indeed a rather obvious application of photography).
