hone from the addition of a motor, the replacement of shellac discs with vulcanite, and the mass-duplication of cylinders made from celluloid.
One recording technique that was developed in the late 19th century and is considered superior in sound quality to other stereo recording techniques to this day is the binaural recording technique, though it was note patented as a stereo recording method until one was awarded to Alan Blumlein in England in 1931 (Schoenherr 6). The biggest reason binaural recording techniques offer superior sound is because of their superior spatial performance compared to other recording methods “The basic idea of the binaural recording technique is to record and reproduce signals to the human hearing accurately. This is done by replicating the sound pressures at both eardrums” (Jarvinen and Maijala 1). While the use of an artificial head dominated binaural recording techniques, it is possible to use a real human subject fitted with microphones. Recent studies have demonstrated this kind of binaural recording techniques to be as effective in creating realistic sound as the use of artificial heads “The quality of real head recordings made using a randomly selected subject is at least as good as artificial head recordings” (Moller 171).
In 1931, Dr. Fritz Pfleumer and AEG began to build the first magnetic tape recorders. Innovation of stereo recording techniques and equipment would continue through the first decade of the twentieth century, including the first phonograph to come with a tapered tone arm, a ten-inch disc that had a 4-minute capacity, and the introduction of the Victrola “Victor introduced the first all-enclosed cabinet phonograph in 1907…widely advertised as the ‘Victrola’ upright with enclosed tapered horn; Victor would spend $50,000,000 on print advertising and $17,000,000 on catalogs and brochures by 1929, creating the generic name victrola that is applied to all phono...
