The measurement of sound arrival-times at the hydrophones of a three- dimensional array has been the difficult part of the analysis for biological acoustic source location. The development of a system that relegates these signal comparisons and measurements to computer analysis is described. The essential steps which require human judgment are retained allowing a flexible analytic procedure that requires less time, has greater accuracy, and less operator bias than manual measurements.
