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.
