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? > > I wondering how Mr "x" (ack, btw) calculates time?
