Bass boost settings
De-emphasis
De-emphasis is controlled by bit 4 of control register 0. The de-emphasis filter can be switched on or off. The digital
de-emphasis filter is dimensioned to produce the de-emphasis frequency characteristics for the sample rate 44.1 kHz.
De-emphasis is synchronized to the sample clock, so that operation always takes place on complete samples.
