Howto calculate the delay time
The optimum delay time varies depending on the position where the
listener is located. Calculate the optimum delay time referring to the
following illustration,
Delay time (ms) = 20 ms + 3 ms x (A - B)
For example, if A = 5 m and B = 3 m;
20 ms + 3 ms X (5 - 3) = 26 ms
