Digitally Enhanced Shotgun Microphone with Increased Directivity
Shotgun microphones are still state-of-the-art when the goal is to achieve the highest possible directivity and S/N ratio with high signal fidelity. As opposed to beamformers, properly designed shotgun microphones do not suffer greatly from inconsistencies and sound color artifacts. A digitally enhanced shotgun microphone is proposed, using a second backward-oriented microphone capsule and digital signal processing with the goal of improving directivity and reducing diffuse gain at low and medium frequencies significantly, while leaving the sound color essentially unchanged. Furthermore, the shotgun microphone's rear lobe is attenuated in level.
