How stereophonic sound systems work. The main diagram shows a simplified situation in nature. The inset shows the electronic simulation. Notably, such electronic systems require more than one speaker. Time difference in a stereophonic recording of a car going past
Over the next two years, Blumlein developed stereo microphones and a stereo disc-cutting head, and recorded a number of short films with stereo soundtracks. In the 1930s, experiments with magnetic tape enabled the development of the first practical commercial sound systems that could record and reproduce high-fidelity stereophonic sound .
Named after its early proponent audio engineer David Hafler, the circuit exploits the high amount of stereo separation between Left and Right channels and sound phase. [2] This type of system is called 2:2:4, since the rear channels are simulated from a two-channel stereo track, with no actual extra tracks encoded. The rear channels will ...
The systems all did this in similar (but not completely compatible) ways. As with FM stereo, all of the AM stereo designs used pilot tones (unheard parts of the broadcast signal) to alert the receiver electronics that a stereo signal was coming in and to switch the receiver into the proper decoding mode. [4]
In the CD-4 system, the quadraphonic audio was divided into left and right channels, which were recorded orthogonally in the vertical plane of the disc groove, which is the case with normal stereo. The CD-4 record track is broader than a conventional stereo track, so the playing time is less than a conventional stereo record.

There’s a moment in David Adjmi’s play “Stereophonic” when a discordant, mid-’70s band-on-the rise hears one of its songs played back to them in the recording studio for the first time ...
Since they are para-virtualization stereo systems, the major goal of them is to simulate stereo sound information. Traditional stereo systems use sensors that are quite different from human ears. Although those sensors can receive the acoustic information from different directions, they do not have the same frequency response of human auditory ...
