Abstract :
An auditory evoked potential and psychoacoustic system which integrates a host personal computer with an Ariel DSP-16 digital signal processing board for optimal flexibility in the design and programming of experiments are discussed. The software on the signal processing board operates in parallel with the ASYST scientific language on the host computer. The system allows for the elaborate sequencing of digital stimuli and signal averages, in parallel with real-time processing for quality control. A library of easy-to-use macro functions is provided for customized algorithm development to realize innovative experimental protocols. Because the system is centered in a personal computer, it is an inexpensive yet powerful experimental tool
