Directional microphone



Dear All,

        Is  it  possible  to  simulate  the  effect of a highly directional
microphone  using an array of two or more omni-directional microphones ?  I
suspect  that  this could be done by using a simple time-delay filter,but I
am not sure how...

        Any ideas or pointers ?

Thanks in advance,

Argiris Kranidiotis.
