| With vinyl technology, technical problems and requirements always exist and without any doubt, are inherent in phonographic recording. Whereas both phonograph recordings and audiotape have a limited dynamic range and frequency response, compared to the compact disc which has both a greater dynamic range over 90 decibels and a linear frequency response from less than 20 hertz to over 20,000 hertz, in fact this proves to be much greater than that of the range of the human ear.
