Speaker delay calculator
Distance offsets → millisecond delay for time-aligning speakers.
Compute the delay you need to push into your DSP so two (or more) speakers arrive in phase at the listener. Speed of sound follows the air temperature you enter (°C or °F); default 20 °C.

Distance is always measured from the front row, not the previous row. Some designers add a few extra milliseconds (the "Haas trick") so the front row perceptually localizes the sound source — keeps the audience feeling like the music is coming from the stage.
Speed of sound used: 343.4 m/s (1127 ft/s) at 20.0 °C
multi-row layout (top view)
Each row behind the front gets its own delay so its wavefront re-aligns with the front row's late-arriving sound.
