The linear taper is, well, linear; the audio taper is logarithmic, so,
for a volume control, you'd want to use an audio taper as your hearing
is non-linear.  For most other things, you'd usually want to use a
linear taper.

In that schematic, it looks like R7 would be an audio taper pot, and, R5
and R1 would be linear taper pots.   Am I overlooking anything?
