The DAC's output is analog.

that's why the second letter is 'a'. digital-to-analog converter.

The tuning I am referring to takes place
inside the DAC.

unlikely, but regardless, it's an alteration which can be done outside
of the dac, either in the digital or analog domain, or both.

A DAC gets fed with digital data.

that's why the first letter is 'd', for *digital* to analog converter.

This defines the wave form in finite
steps. The job of the DAC is to output an analog wave form which is as
close as possible to the original analog signal. Turning digital data
into analog is not easy or straight-forward. That's why there are so
many ways of trying to do it.

it's very easy and very straightforward, and no, there aren't 'so many
ways', at least not correct ones.
