Technology

Ambisone offers ahead-of-the-game far-field voice pickup technology, which goes far beyond common hands-free algorithms. This includes accurate 3-D localization of multiple speakers and noise sources by using acoustics only. On this basis advanced speech processing is used to extract a crystal-clear speech signal. The algorithms run on embedded hardware and are wrapped up in an appealing product design while maintaining full acoustical performance.
