How can we make surround recording for pure audio applications more successful? Musical content and good sound (among other concerns) are as important in surround as they are in two-channel stereo. But the manufacturers of home playback equipment and the producers of program material have not yet exhausted all the possibilities. Surround must offer both localization and a sense of spaciousness throughout an enlarged listening area if it is to justify its higher costs. Success therefore depends greatly on the use of recording methods which extract maximum benefit from the center channel. Various possibilities exist for surround microphone arrangements; eight different methods for 5.0 pickup will be described, along with the issues of crosstalk and "stereo down-mix compatibility."
