DSP-Implemented Broadband Superdirective Microphon e Array with Audible Noise Suppression
In this proposed paper, a novel microphone linear array is presented and implemented for real-time processing. The prototype works on a DSP board and operates in the frequency domain. The array, which is composed of 15 microphones in nested configuration, combines two multichannel techniques for speech improvement: SuperDirective beamforming (SD) and Audible Noise Suppression (ANS). The SD beamforming technique is an alternative to conventional or Delay and Sum beamforming (DS) which has worse low frequency spatial selectivity. ANS processing is based on the masking properties of the human auditory system and can benefit the perceived and objective quality of the processed signal. Several on-line experiments will be described, assessing the real-time prototype.
