Formula and source

Speed of sound c = 331.3 + 0.606 × T_C (m/s). Delay-tower delay (ms) = distance_m / c × 1000. Haas-window offset 10-30 ms recommended for delayed system natural-source perception.

Classical acoustics; AES (Audio Engineering Society) information documents on time-alignment by name.
