A multi-purpose voice recording and encoding device using a micro computer

Abstract

A device for recording and encoding voice stimuli was developed with the NEC-PC 9801 micro computer. Sampling times are 100μs (10kHz), and one recording time can be lasted up to 15s. The sound stimuli are monitored on the computer display. These stimuli could be edited directly by the cursor and saved onto a floppy disk. A multi purpose program was also developed for this apparatus. This program allows the user to manipulate the stimuli for various auditory experiments such as dichotic listening tests etc.
