AB  - The paper presents Long Range Noise Canceling (LRNC) microphone array technology developed in Alango Ltd. LRNC is a digital signal processing technology utilizing near field signals from two unidirectional or four omnidirectional microphones. It allows differentiation between user 's voice originating in a closed region in front of LRNC microphone and other sounds that are effectively blocked. The pick up range of LRNC microphone may be as large as 70cm in front of the microphone and, if necessary, may be easily reduced by changing corresponding software parameters. This unique property makes LRNC microphone attractive for a variety of voice applications where distant sounds, noises or acoustic echoes must be blocked.
