The fundamental idea behind this PlugIn is a hundred percent accurate computation of the deceleration time in consideration of the effects of the temperature on the speed of sound. "Exact Delay" has primarily the purpose to solve problems caused by run-time -differences of different microphone signals to adjust. Therefore it offers the possibility to enter the distance in centimeters and it generates, in dependence of the temperature and the speed of sound, the necessary delay time automatically. It can, however if necessary, also be used as a calculating help, without really retarding audio data in real time.

Usually for the calculation of the delay time the constant value of the speed of sound is used at a temperature of 20° Celsius. This value amounts at this temperature 343 m/s..
