Forgot to add - insert the measure delay into the start of the preceding
I doubt it is a micro second -
If the delay is constant here is what you can do
Split the stereo track to mono
use "analyze ->splot spectrum-and use the autocorrelation
get rid of the grid
if the delay is constant you should see a sharp peak
export the date and you can zero in on the delay with the largest peak -
artificially 0.1 second in the sample I sent.
If the delay is not constant the peak will be smeared so pic the
midpoint or throw one channel away or save it separately if it is
smeared over too wide a time distribution
