12.9.3 TAKING THE MEASUREMENTS
You are now ready to begin the measuring session. We suggest you to take an
initial measurement (with the speaker in place over the turntables in position 0 –
on-axis - and with the turntables link button not pressed) to verify all the
parameters, especially viewing the acquired impulse response and setting the start
and stop values of the measurement window. These values will be applied to all the
measurements taken; consider, in this respect, the problem of the trajectory of the
acoustic center of the speaker during the rotation.
The last thing to do is to start the procedure by clicking the start button on the
turntables control dialog:
Figure 12.21
A message box alerting about the number of measurements that will be taken is
showed:
Figure 12.22
After the 73 measurements are taken the session should end while the autosave
reset. The procedure can be halted and restarted from the point where it stopped
using the stop and resume buttons in the turntables control dialog.
