Dynagroove

From Wikipedia, the free encyclopedia

Dynagroove is a recording process introduced in 1963 exclusive to RCA Victor that, for the first time, utilized computers ("electronic brains") to modify the audio signal fed to the recording stylus (chisel-shaped) of a phonograph record to make the groove shape conform to the tracking requirements of the playback stylus (ball-point shaped). RCA indicated that Dynagroove had the effect of adding brilliance and clarity, realistic presence, full-bodied tone and virtually eliminated surface noise and inner groove distortion. In addition, Dynagroove recordings were mastered on RCA Magnetic Tape. Hans H. Fantel (who wrote liner notes on the first Dynagroove releases) summed it up with, "[Dynagroove] adds up to what is, in my opinion, a remarkable degree of musical realism. The technique is ingenious and sophisticated, but its validation is simple: the ear confirms it!"

The process was not received well by some industry commentators, such as the founder of Stereophile magazine, who in December 1964 wrote a highly unfavourable article entitled "Down with Dynagroove!".

Not to be confused with Dynaflex, a technique of reducing the thickness and quality of vinyl used in mass-market L.P. manufacturing also marketed by RCA Victor.
