Well i guess encoding absolute time should not be too hard.
A simple solution could be to have the two stereo channels with different
frequencies, with the ratio corresponding to the radial position.
Or is that not accurate enough?

How fine-grained is the time resolution of the final-scratch system?

Rising slope, i guess.
