I have just released a tool for simulating the response of microphone beamforming arrays. This allows you to simulate the spatial and frequency response of a two-microphone array in either an endfire or broadside configuration. Full documentation for the installation and use of the tool is on the Analog Devices wiki page here. There is both a 64-bit and 32-bit version available for Windows PCs and the tool requires that you either have Matlab or the Matlab Compiler Runtime installed.

The tool can be used together with the application note on Microphone Beamforming Arrays (AN-1140). The tool is basically an interactive version of the application note and is what was used to generate all of the directionality and frequency response plots in the app note.

 

Here is a screen shot of the tool itself. Feel free to leave any comments or suggestions below. I hope that this is useful for anyone investigating multi-microphone arrays.
