Autodirective Dual Microphone
The paper describes Autodirective Dual Microphone (ADM) technology and its applications. ADM digital signal processing technology developed by Alango Ltd. is a far-field, adaptive beamforming technology that uses only two closely spaced omnidirectional sound pressure sensors. ADM technology provides the optimal and variable directivity in every frequency region. The adaptation time is very fast leading to very good improvement in signal-to-noise ratio in fast changing noisy environments. Contrary to regular directional microphones, an ADM technology based microphone is much less sensitive to wind noises and does not a proximity effect. Its DSP implementation is simple requiring very modest computational resources.
