Abstract
The present invention comprises an adaptive directionality dual microphone system in which the time domain data from the first and second microphones is converted into frequency domain data. The frequency domain data is then manipulated to produce a noise-canceled signal which is converted in an Inverse Fourier Transform block into noise-cancel time domain data.
