Columbia claims that the tone of its phonograph, which will sell for $139.50 and $144.50 (depending on the cabinet), is a match for all but the most expensive custom-made hi-fi sets. It reproduces tones from a low of 50 cycles per second to a high of 12,000 (the ordinary hi-fi range), compared to a smaller tonal range of 80-6,000 c.p.s. in most phonographs. Columbia gets its reproduction chiefly by an extra thick, solid wooden cabinet (which eliminates "tinny" vibration) and two 6-in. speakers located at each side of the phonograph, instead...
...living room to make his recordings sound just as good as a performance in a concert hall-maybe better. Half a dozen years ago, there was hardly a platoon of them in the whole U.S. Last week in Manhattan, 15,000 of them trooped to the fourth annual hi-fi roundup, known as the Audio Fair. Partsmakers and plain fans, they took over 116 rooms of the New Yorker Hotel, set up their wares and turned on the switches...
There was plenty to sample in the resulting hi-fi bedlam-speakers that looked like kettledrums or corner cupboards, tape recorders the size of a wallet or a washing machine, amplifiers that cost from $40 to $400, complete hookups from $150 (Spartan economy) to $3,500 (Sybaritic luxury). But as the fair went on, most of the excitement centered around something called "binaural" (or "stereophonic") sound. Aim of binaural sound: to give the ears the same effect of realistic "presence" that Cinerama films-or the old-fashioned stereoscope-give the eyes...
...early radio engineers and, in the recording field, by Manhattan's Audak Co. a generation ago proved that it was technically possible to get extremely high fidelity of tone by the use of duplicate, spaced microphones, duplicate recordings and duplicate speakers. It has taken the popularity of hi-fi to bring the idea out of the labs. Last week two tape recorder manufacturers, one disk equipment firm and one record company were demonstrating working models...
