5.3 Automatic Calibration Using GLM AutoCal
GLM AutoCal is a powerful monitoring system calibration algorithm running in the Genelec Cloud.
Sweeps are generated by each monitor in a group. Responses are recorded with the GLM
measurement microphone into your computer.
NOTE: Adaptive Woofer Systems will be calibrated in WooferCal page after Autocal and
Autophase.
The algorithm analyzes the sweeps and calculates the frequency responses for all monitors and
subwoofers, then optimizes level and delay to compensate for differences between monitors, and
sets equalization for the individual room responses to remove colorations caused by the room and
the location where the monitors have been installed. The end result is to have sound from all
monitors arriving at the listening position at the same time, same level, and compensated for the
effects of the room acoustics, resulting in very accurate imaging and reliable monitoring.
Each monitor group has its own acoustic settings. This is one of the important features of GLM.
Each setup file can contain several preset definitions. Each monitoring group can have different
AutoCal calibrations.
Even the same set of monitors you can have several calibrated listening positions. To do this,
define each position as a new group preset and then calibrate each preset separate. For example,
one group can be ‘Engineer Position’ and another ‘Producer Position’. Each can have its own
