Microsemi AcuEdge™ Technology
HD Voice Audio for IP Camera
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 AcuEdge™ 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.
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 solu-
tions 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 moni-
tor 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.
