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. Uses the speed of sound at 20°C — adjust the temperature if your room is unusual.

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
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.
