accuracy depends on the accuracy of MCLK. If MCLK changes, the sample rates change
proportionately.
Note that some sample rates (e.g. 44.1kHz in USB mode) are approximated, i.e. they differ from their
target value by a very small amount. This is not audible, as the maximum deviation is only 0.27%
(8.0214kHz instead of 8kHz in USB mode). By comparison, a half-tone step corresponds to a 5.9%
change in pitch.
