Pre-D/A sound card output amplitude

These settings will set output:

Inverts the output signal if it is checked. If the measured impulse response has a negative peak, toggling this will invert the peak.

The edit box gives the full-scale amplitude in Decibels of the measurement output signal (and for the relative sound card mixer calibration). Its maximum value is 0, which is the maximal amplitude for the Digital-to-Analog converter.

The edit box gives the full-scale amplitude in Decibels of the signal used for absolute calibration of the sound card.
