Abstract : Subcontractor (Southwest Research Institute) provides a description of the hardware assembled and software created to develop the 3-D AOI. A macintosh llx computer is the heart of the system, acting as a general controller and processor of data flowing from the Flight Information Package to the Audio Localization Cue Synthesizer, audio mixer, headphones, and data recording equipment. A National Instruments NB-DSP2300 digital signal processing board and NB-A2100 audio 1/0 board generate the audio signals, and National instruments LabView software is used to control the auditory display. The majority of this report is a description of the 18 LabView software modules created to control the 3-D AOI display.
