I am planning to use "Screen('PlayMovie'..." to play a large set of QT
movies. The trick is that I would like to be able to separately
manipulate the left and right sound channels in the stereo audio
track. Basically I would like (on a trial by trial basis) to decide on
the amplitude and onset (start time of playback) relationship between
the left and right channels so as to adjust the perceived location of
the sound in space. PlayMovie doesn't seem to have any hooks for
controlling the sound playback independently of just starting the
movie playing (I could easily control the relationship and position of
the image based on how images in the movie sequence are shown...). Any
suggestions? Mario - is there a way to manipulate the sound data
structures and then use PlayMovie?
Thanks, Mike Tarr
