I am guessing you want to do more than just present a dichotic stimulus and that there is a psychoacoustics experiment underlying this question. There are a number of toolboxes that you can use to do psychoacoustic experiments ...

MLP is a MATLAB toolbox for doing auditory psychophysics

Psychtoolbox is a MATLAB toolbox for doing general, including auditory, psychophysics

If you are willing to leave MATLAB, I would suggest looking at the Python package PsychoPy
