> There is no reason the DAC or ADC can't internally do the resampling itself. You are describing alternative (b) i mentioned above: digital filtering plus oversampling. This also isn't without side effects. Oversampling a 44KHz signal is not the same as having a 192Khz material to start with. Very different.
