If you mean piecemaker it is rather dangerous place to change it, but for now it is only available there, and this file will be changed in today update:
http://www.modularweb.net/content/en/piecemaker/documentation.pdf here is documentation, but if you wish to change delay between slides search for Autoplay="10" in file airborn/advance/shortcodes/sliders.php line 90 in new update. 10 is number of seconds. You will have to change it again after update of theme(in future will move it to theme options). Hope that helps.
