The popular history of quadraphonics (4-channel sound from LP records, tapes, and radio broadcasts) chronicles a spectacular failure. The major record labels, led by CBS/Columbia and JVC/RCA, invested millions in ill-fated schemes to convince music lovers to ditch 2-channel stereo for 4-channel surround sound. The concept was killed, so the story goes, by competing and incompatible LP formats, high prices on the better-sounding discrete-channel reel tapes, and a collective shrug by the buying public.
That story is mostly true, though the format thrived for a while in Japan and Germany, and it never fully died. Now, modern tech has made possible rereleases of 1970s quad albums on relatively common formats: multichannel SACD and Blu-ray discs (BD). No more “meh” LP formats, no more fussy 1970s-tech decoders.
With a few hardcore adherents in the worlds of professional recording and music labels, the quad fire was never fully extinguished. Very early drafts of the “Red Book” Compact Disc standard included provisions for four audio channels; in fact, there were fringe efforts to revive quad on and .
