Which company proved instrumental in encoding multichannel audio, such as with Dolby Stereo in the late 1970s?

Answer

Dolby Laboratories.

Dolby Laboratories played a pivotal role in standardizing and delivering cinema-quality audio separation to a wider audience, bridging the gap between theater technology and home electronics. Their technological contributions spanned from early work on noise reduction to the development of sophisticated multichannel audio encoding methods. Specifically, the introduction of Dolby Stereo in the late 1970s began translating cinema sound separation capabilities, first via optical film prints and subsequently through encoded signals provided for home video releases, establishing a standardized method for delivering audio channels beyond just the traditional left and right.
