Magnetic Sound Recording

Magnetic sound recording was one of the important inventions by using magnetic tape and the tape recorder. On this page we will look into the details about magnetic tape sound recording. Read on.

Paper-based tape was first used for Magnetic sound recording but it was soon outdated by polyester and acetate backing. However, as Acetate was more fragile and breakable than polyester, it went out of the picture soon. The basis of the technology behind magnetic tape sound recording was invented by German audio engineers in the 1930s. Discovering the technique of AC biasing, they significantly improved the frequency response of magnetic tape for sound recording. American audio engineer John T. Mullin with the help of Crosby Enterprises perfected Magnetic sound recording just after the war. In the late 1940s, Ampex Company was the first to produce the first commercially available tape recorders based on Magnetic sound recording.

Magnetic tape for sound recording brought about revolutionary changes in both radio and the recording industry. Now, sound could be recorded, re-recorded or erased on the same tape many times. The sounds could be copied from tape to tape with only slight loss of quality. It was possible to edit the recordings very precisely by physically cutting the tape and rejoining it.

Within a few years of the introduction of the first commercial tape recorder, the first multitrack tape recorder was invented by American musician-inventor Les Paul. This opened the path for the audacious sonic experiments of the Musique Concrète school and composers like Karlheinz Stockhausen. This in turn led to the original and new pop music recordings by artists like Frank Zappa, The Beatles and The Beach Boys. The Magnetic sound recording had changed the face of music for ever.

Magnetic tape sound recording also helped the radio industry to pre-record many sections of program content for the first time, for example advertising, which earlier had to be presented live. It was also possible to create and duplicate complex, high-fidelity, long-duration recordings of complete programs. Using magnetic tape for sound recording also led to innovations like multi-tracking and tape echo, which allowed the radio programs and advertisements to be pre-produced. The sophistication and the level of complexity that was previously unattainable, was possible, thank to the introduction of Magnetic sound recording.
