In complex noisy environments, Microsemi's AcuEdge Technology cancels echo and reduces ambient noise. While 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. 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, sound location, and beam forming capabilities. The ZL38052 audio processor increases the functionality by enabling surveillance of smoke detectors (T3), carbon monoxide detectors (T4) and provide glass break detection. 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 Getting Started Use the following resources to explore: Microsemi AcuEdgeTM Technology MiTunerTM Automatic Tuning Kit * ZL38050 IP Camera Audio Processor * ZL38051 Advanced IP Camera Audio Processor * ZL38052 Advanced IP Camera with Sound Classifier Audio Processor * MiTunerTM Information * MiTunerTM GUI Software Guide * ZLS38508 MiTunerTM GUI Microsemi Timberwolf TM Audio Processor HD Voice Audio for IP Camera Features and Benefits * * * * * * * * * * * Flash Full duplex AEC (Narrowband and Wideband) Mid field audio pick up to 3 meters (ZL38050) Far field audio pick up to 10 meters (ZL38051) Sound location estimation (ZL38051) Beam forming for effective noise attenuation (ZL38051) Long tail echo cancellation (up to 256 ms) Advanced Noise Reduction to reduces background noise from the near-end speech signal Equalizer Howling cancellation: prevents oscillation in echo canceller audio path Smoke/CO alarms detection (ZL38052) Glass break detection (ZL38052) SPI Analog Amplifier ZL38050/51/52 Digital PCM VoIP PoE Ethernet SPI/UART Microprocessor Camera Motor Control LCD Display Control Room IP Camera Block Diagram Microsemi Auto Tuning Tool (ZLE38470) Microsemi's MiTunerTM Kit eases the system tuning complexity and speed up design cycle for quick development.
