Context: <response>: 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 gats waka far from side to side, wey go make the groove wide, wey go chop space and limit the time wey the record fit play. At high frequencies, noise, pops, and ticks dey plenty. These wahala fit reduce if dem use equalization wey everybody don gree on. During recording, the size of low frequencies dey reduce, so the groove width wey dem need go reduce, and the size of high frequencies dey increase. The equipment wey dem go use for playback go boost bass and cut treble so the original sound balance go dey intact; e go also reduce the high frequency noise. So more music go fit enter the record, and noise go reduce.
