A computer program for sequencing and presenting complex sounds for auditory neuroimaging studies

This paper describes a computer program, named ASAP (audio sequencing and presentation), that runs on IBM PC compatible hardware with a Microsoft Windows operating system and has been specially designed for facilitating auditory neuroimaging studies. The program's main characteristics are: (1) the ability to generate sequences of complex sounds; (2) an easy-to-use, graphical user interface; (3) full compatibility with Microsoft Windows 95 or later and Windows NT version 4.0 or later software; (4) precise timing of selected sound sequences; (5) the capability of triggering other devices; (6) the capability of being triggered to deliver stimuli; (7) support for both monotic and dichotic sound sequences; and (8) rudimentary support for the simultaneous presentation of pictures/text and sound.
