Basic operation
Compute the delay
Press the 
button to find the delay using the most recent incoming audio.
The resulting figure is displayed almost instantly as a:
- Delay in samples (smp).
- Distance in meters (m) or Imperial feet (ft.) depending on whether Metric system is enabled.
- Delay in milliseconds (ms).
Compensate the delay
Pressing the 
button activates a delay line in the source signal path to compensate for the currently displayed delay value, effectively time-aligning source and response signals.
Pressing again deactivates the delay line, which allows for quick comparison between uncompensated and compensated signal paths.
Fine-tune manually
If necessary, you can manually adjust the delay figure using either of these methods:
- Direct keyboard numeric value entry as time or distance figure.
- Increment / decrement by clicking the +/- icons.
- Increment / decrement using the +/- numeric keys.
Perform a new measurement
Press the button again to perform a new measurement.
This will overwrite any previous value.
