Sound Tools

Calculate the delay time needed for secondary speakers based on distance from the main source. Accounts for temperature and humidity effects on the speed of sound.

Calculate voltage, current, resistance, and power using Ohm's Law and the power equation. Enter any two known values to solve for the rest.

Convert between delay time in milliseconds and the distance sound travels in feet or metres. Adjustable for ambient temperature and humidity.

Calculate total impedance for series, parallel, and series-parallel speaker wiring. Supports mixed impedance drivers with power share and amp safety checks.

Combine dB levels, calculate inverse square law distance attenuation, and convert between dBu, dBV, dBFS, Vrms and Watts.
