12.10.3 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 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 12.24
A message box alerting about the number of measurements that will be taken is
showed:
Press Yes. After each MLS measurement is taken you will see the turntables
rotating and CLIO waiting the specified delay time before automatically taking the
next measurement. Should this time be insufficient you have to reset the turntable
delay value accordingly. The autosave function will refresh the file name after each
measurement (Fig.12.25).
Figure 12.25
After the 2664 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.
