Ah you must mean this:
http://en.wikipedia.org/wiki/Stereo_imaging
Your delay idea only covers one part of the psychoacoustics of the stereo image: the difference in time when a sound reaches each ear. Psychoacoustics are a bit more complicated than that I'm afraid. You might look up HRTF (head related transfer functions) to get a better idea of the time differences involved. But there are a lot of other factors. An intro book on psychoacoustic might be a good place to start.
Maybe some of the ambisonics experts around here will chip in some other things...
best, Derek

What is an imager supposed to do? I've never heard of this effect and Google isn't too helpful on the subject.

hello people,
i like to build an imager effect in pd but have some trouble with it. what i´ve acually tryed is very simple: sending one signalchannel of an stereo pair into delaywrite~ (while the other goes directy into dac~) after 6 - 26 ms later i read out of it with delread~ and is connected to the second input of dac~.
is this the right way to build an imager?
does anybody know the theoretic background of the imager?
some other ideas how i can do an imager in pd?
