DOASimulation

Overview

Simulate specified DOA for specified mic array

Discussion

This module implements a synthesized direction of arrival for a specified mic geometry. Module argument NUMMICS sets number of microphones. Module parameter MicPositions allows user to enter x,y coordinates of the microphones. Module parameter Angle appears on inspector and allows user to select direction of arrival. A mono signal is input to the module. The module outputs a N channel signal with delays set to simulate the desired DOA.
