Post your code in the body of the message, then highlight and click the {}Code icon. Do not post your code as tags.

The pattern is associated with the array itself. Once the beamform is obtained, the wav file is just a time domain representation, all the spatial domain information is collapsed in it. Therefore I'm not sure if you can recover the pattern from the wav file, unless you have wav file for each direction.
