From simple sounds to music, and from still images to videos, various audio-visual stimuli can be provided. Dedicated hardware enables synchronization that is difficult to achieve with software alone.
The audio-visual stimulus system EFRP-ST is designed to meet the creative needs of researchers, featuring simple sound stimuli for event-related potential measurement and auditory experiments, as well as complex sequence stimuli and video display functions. - High-performance graphics with a refresh rate of 360Hz and a response speed of 1ms - Variable refresh rate synchronization function eliminates tearing and stuttering during image presentation - Supports sound stimuli, still image stimuli, and combined audio-visual video stimuli - A cost-effective image presentation system can be achieved by combining optical sensors with vertical synchronization on standard monitors - Easy to set trigger thresholds based on the display's emission state and emission patterns - Capable of simultaneous audio and visual stimulation, making it ideal for multimedia-related research - Dedicated hardware and stimulus-specific software enable high-speed repetitive stimulation and precise synchronization timing - Equipped with specialized functions for easy creation and editing of stimulus sounds, setting trigger positions for videos, and constructing stimulus patterns - By classifying stimulus forms into nine types, it efficiently accommodates diverse experimental sequences.
