Mechanical modelling of the frequency response of a vinyl audio turntable : comparison with digital music formats

This project serves to investigate how the frequency spectrum of vinyl music, specifically stereophonic vinyl Long Play records played at a speed of 331⁄3 rpm on a 12-inch disc, compares to that of high-temporal-resolution digital music. We have developed an electromechanical model for the frequency...
