I recently (maybe a couple years ago) did a redesign of a product that sent audio through an audio taper pot. In the new design, DC is put on the pot, the wiper voltage measured, and a gain value sent to a DSP. I ended up going with a linear pot because the resolution "at the bottom" of the pot was poor.
