Abstract: A computer-implemented method executed by data processing hardware that causes the data processing hardware to perform operations to design an audio filter. The operations include receiving multiple audio signals from a sensor array, the multiple audio signals including a target audio signal and interference audio signals and leveraging the interference audio signals. The multiple audio signals are processed using short-time Fourier transform (STFT) for each of the multiple audio signals. The operations also include designing the audio filter using the determined prior-SNR and enhancing the target audio signal using the leveraged interference audio signals and the designed audio filter and attenuating the interference audio signals.
