[PD] Measuring position between two microphones?

Hi,
I made a patch to locate the position of a sound source between two
microphones, which looks like this:
[adc~]
| |
| [threshold~ 0.2 100]
| |
[threshold~ 0.2 100] |
| [delay 10]
| |
[timer]
So a number of 10ms means that the source is exactly between the two
microphones. This patch works kind of reliable and accurate. But I was
wondering if there is a better possibility with higher resolution? At
the moment I can distinguish the position with an accuracy of 1.333 ms,
means I get about 12 different values out of my tube.
Has anyone an idea how I can get more precise readings? I thought about
comparing the amplitudes of the two waves I get, but I have no idea how
to do this or if this would be more exact.
Thanks for any help,
Chris
