Yes, with loop-back, no end-check

Same as the mode above, except that the end-check is not performed. This means that this mode measures the initial time delay exact, but errors in the measurement caused by non-continuous play or record are not detected. The loop-back settings (see below) must be properly set.

 

gives the delay of the sound card in samples. This is found by doing a MLS measurement of the sound card with its input connected to the output using a cable. Plotting the first part of the resulting impulse response using Time Data as plot-type and Samples as x-axis, will show the delay.
