Audio Delay Calculator: planning guide
Sound arrival time
Sound travels through air at approximately 343.4 metres per second near 20 °C. The speed changes with temperature, so an acoustic offset expressed in distance should be converted using the current environment. The acoustic arrival-time estimate equals distance divided by speed. At 20 °C, a 10-metre path takes about 29.1 milliseconds.
Understanding DSP delay
This calculator translates distance to milliseconds and sample equivalents. It does not tell you unconditionally which speaker to delay. In a distributed loudspeaker design, the technician measures arrival times at the alignment position and delays the earlier-arriving source if appropriate, also considering precedence, coverage geometry, system processing, and artistic goals.
Recording and digital audio
At 48 kHz, one millisecond represents 48 samples. Convert the total time to samples when programming a delay line or comparing digital timing. Added offset may represent measured processing differences. A negative final result means the proposed net setting is not a valid positive delay on a simple delay processor; revisit the alignment plan.
Common questions
Does temperature matter at indoor events
A few degrees changes acoustic travel time slightly, especially over longer distances.
Will this calculate video lip-sync delay
It provides a physical timing conversion, not an end-to-end latency measurement of video and audio devices.
