The 1950s affered a combination of sounds name five?

Answer 1

A system of sound recording or transmission in which two or more http://www.answers.com/topic/microphone channels are connected to corresponding loudspeakers in the listening room in order to create a sound field at the listener's ears which is perceived to be very much like that in the original space. Binaural is a special form of http://www.answers.com/topic/stereophonic sound in which two microphones replace the ears of a http://www.answers.com/topic/dummy head and are connected through an amplifier/recorder system to a pair of headphones worn by the listener. Quadraphonic is a special case of stereo in which four channels and loudspeakers are employed. There are three basic microphone techniques for stereophonic pickup: http://www.answers.com/topic/coincident, spaced apart, and individual instrument (also called close milking). The techniques are sometimes combined. The coincident technique employs two microphones located very close together, often enclosed in the same case. Usually the two microphones will have http://www.answers.com/topic/cardioid pickup patterns, or one will be a cardioid and the other a figure-eight. The coincident technique relies only on differences in sound intensity to determine position of the phantom images. See alsohttp://www.answers.com/topic/microphone. By placing the microphones several feet apart, it is possible to provide a good pickup of a large group without moving the microphones as far into the reverberant field. The spaced-apart technique provides both time and intensity cues. Beginning in the late 1960s it became common for most popular music to be recorded in an acoustically dead studio using a large number of microphones, each located close to one instrument or small group of instruments. By proportionally mixing the microphone outputs between the two stereo channels, it is possible to provide the intensity cues necessary for perceiving phantom images. No time cues are produced.
