Microsemi AcuEdgeTM Technology Microsemi AcuEdgeTM Technology for the Connected Home Microsemi AcuEdgeTM Technology HD Voice Audio for IP Camera New High-performance Audio Processors Enable the Streamlined Development of IP Camera for HD Voice Capabilities Designed for High Definition (HD) Voice 2 way audio in IP Camera, Microsemi's new audio processors ZL38050 and ZL38051 feature the company's innovative AcuEdgeTM acoustic technology, which is a set of highly-complex and integrated algorithms that allow the user to extract intelligible information from the audio environment from which they are communicating. ZL38050/51 Block Diagram Audio Processor for IP Camera Microsemi's AcuEdge Technology integrates industry leading features and dedicated firmware to deliver high-quality hands-free voice performance while reducing system design complexity. In complex noisy environments, Microsemi's AcuEdge Technology cancels echo and reduces ambient noise. While the most solutions deliver only half-duplex operation, Microsemi's proprietary algorithm is able to converge and track changes in the echo path to support full-duplex operation. DVR, NVR, or security camera users have difficulty trying to monitor a large number of video feeds for certain incidents, crimes, or events. By adding audio to the surveillance camera, it will enable security personal at the control room to make judgment calls on security concerns. Microsemi AcuEdge Technology will provide audio enhancement to allow more accurate monitoring. The ZL38051 audio processor adds audio enhancement functions such as far field microphone, detection of sound location, and beam forming capabilities.
