Automatic Terminal Information Service

Beat Frequency Oscillator

Digital sound data that is stored in binary format (i.e., a Microsoft WAVE file)

An output route where sounds are allocated and dispatched

Commercial-Off-The-Shelf

A V+ visual program constructed of objects and ports, connected via nets that are placed upon a worksheet.

Distance Measuring Equipment. This system uses a VHF radio receiver to measure the distance to a tuned navaid

An individual sound card used in the SimPhonics sound system

Digital Signal Processor

Electronic Flight Instrument System

Federal Aviation Agency

Ground Proximity Warning System

Input/Output

A sample that continually repeats itself

Linear Function Interpolator

An event triggered by a simulation model (e.g., a navigation radio model) and sent to the SimPhonics sound system (typically by ethernet).

Specific to this document, a model is defined as a V+ representation of an aircraft sound

A method of sound reproduction whereby one or more sources are routed to a single channel

Radio Navigation Aid transmitter. Provides navigation cues on various instruments in the cockpit

Non-Directional Beacon

The connecting “wire” between V+ objects

One of many V+ constructs used for implementing a design (e.g., Logical And, Logical Or, High Pass Filter, Constant Float, Looped FXDirect Player)

Open Database Connectivity

Public Address

Varying the proportion of an audio signal between channels, typically left and right

A subjective quality of a complex sound that is dependent on frequency, loudness, and intensity, most often measured by frequency. In the SimPhonics sound system, the pitch of a sound is, for all intents and purposes, its frequency.

An input/output object connecting a V+ design to real-world signals

Short for potentiometer. A volume control knob.

Push-To-Talk

Revolutions Per Minute

A digitally stored representation of a sound.

A method of sound reproduction in which two channels are used to give an illusion of a more natural distribution of sources of sound.

Traffic Collision Avoidance System

United States of America

Object-oriented visual application development system created by SimPhonics

Very High Frequency. Navigation and communications radios operate in this bandwidth.

An internal mixing channel of a sound card

Windows digital audio file

A V+ window on which to place objects and ports (saved as a design file)
