Audio Precision analyzers it is possible to measure consistency between a reference signal and different signals. This coherence analysis is carried out using one of the parameters of the Transfer function measurement.

The following example has selected a 30-second audio file with a tone of 1 kHz. This tone has been assigned to output 1 of the generator (which has a connected speaker) and the output of the generator has been set as a reference signal and the average value of Average = 80).

The measurement measures the consistency of the reference signal with input channel 1 signal (which has a connected microphone) and input channel 2 (which has nothing connected).
