      .......in Rolling Stone cited a line that used to appear on album covers throughout the 1960's - as best I recall, the letter asked:

       

      All I want to know is, what the hell is the RIAA high-frequency roll-off characteristic with a 500 cycle crossover?"

        Due to recording mastering and manufacturing limitations, both high and low frequencies were removed from the first recorded signals by various formulae. With low frequencies, the stylus must swing a long way from side to side, requiring the groove to be wide, taking up more space and limiting the playing time of the record. At high frequencies noise is significant. These problems can be compensated for by using equalization to an agreed standard. This simply means reducing the amplitude at low-frequencies, thus reducing the groove width required, and increasing the amplitude at high frequencies. The playback equipment boosts bass and cuts treble in a complementary way. The result should be that the sound is perceived to be without change, thus more music will fit the record, and noise is reduced.

        The agreed standard has been RIAA equalization since 1952, implemented in 1955. Prior to that, especially from 1940, some 100 formulae were used by the record manufacturers.

        In other words it's an encode/decode process that makes music sound better and fit better on one piece of vinyl.
