Signal Delay Used for:
• Compensating for physical placement of multiple drivers in a cluster—to
align points of acoustic origin in the same plane.
• Ensure matching arrival times at listeners from multiple loudspeaker drivers.
• Using the Haas effect to maintain localization of the source, even with a
distributed system.
Signal Generator A device for generating a reference tone for sound system
calibration purposes.
Site file A site file is a file created by G-Ware which is saved on your computer. The
site file contains all information about a particular installation including all unit
settings and properties. It also provides G-Ware with the necessary informaiton to
communicate with the site hardware using your PC.
Site properties The Site Properties window opens when you select New Site from
the File menu or click on the New Site button on the toolbar. It allows you to enter
information about the site as well as configure the communication and security
settings.
Speech Leveler Essentially an AGC applied to a speech signal after processing by
a noise cancellation stage. Acts only on voice signals. Does not pull up the noise floor
during periods of no signal.
Table View Displays the numerical values of the filter parameters for all nodes of
the active filter display.
Threshold The upper or lower level at which a signal processing mechanism begins
or terminates operation.
Unit properties The Unit Properties window opens when you add a new unit to the
site. It allows you to enter information about the unit as well as configure the
communication and security settings.
Virtual reference Virtual references are echo cancellation reference points.
Multiple signals can be included in each of the four virtual references thus allowing
you to reference multiple signals without sacrificing an analog output. You can open
the Virtual Reference window from the G-Ware toolbar or from the Acoustic Echo
Cancellation window.
White Noise Acoustical noise with equal energy throughout a given frequency
range.
