5.2.7 Change Inputs Set-up
This function allows changing the input sensitivity, the input description, the unit name and
the dB reference set-up. This function has been added to allow the calibration of an
existing wave file, which is not recorded with the Tenor system. When opening an external
wave file, the Tenor system generates a standard associated configuration file with an
input sensitivity of 1. Then, the function Change Inputs Set-up can be used to change the
default sensitivity to obtain a calibrated signal. We suggest to estimate the sensibility
correction with a spectrum analysis through the function Average FFT. The dialog box to
change the inputs set-up is shown on the next figure:

The input sensitivities can be changed with the Sensitivity control or using the ±dB control
if the dB correction value is known in dB.
Note: the Start Time control allows changing the starting time of the wave file. This
modification can be useful if absolute time scale for the global historic graph is desired.
