Microsemi AcuEdge
™
Technology
Microsemi’s AcuEdge Technology integrates industry leading features and dedicated firmware to deliver high-quality
hands-free voice performance while reducing system design complexity.
The new Microsemi AcuEdge Technology consists of license-free,
royalty-free intelligent audio IP algorithms. When combined with
Microsemi’s highly-integrated ZL380 series of audio processors,
the solution accelerates customers’ time-to-market via validated
reference design and easy-to-use development tools including the
Microsemi Audio Interface Box (AIB) Kit which utilizes the MiTuner™
GUI software.
Hands-free communications equipment must support high quality
voice in severe noise conditions. For example, speakerphone
designers must compensate for vibration created by plastic
enclosures, echo, and double-talk.
As illustrated in the application block diagrams, Microsemi’s AcuEdge
Technology simplifies design and delivers voice quality improvements
in hands-free communication systems.
In complex noise environments such as large conference rooms and
building lobbies, Microsemi’s AcuEdge Technology cancels echo,
maintains a constant ambient noise (comfort noise) and converges
during double-talk situations.
DVR (Digital Video Recorders), NVR (Network Video recorders) 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 judgement calls on security concerns.
Microsemi AcuEdge Technology will provide audio enhancement to
allow more accurate monitoring.
Microsemi Audio Processor delivers excellent performance in
double-talk situations. While most solutions deliver only half-
duplex operation, Microsemi’s proprietary algorithm is able
to continuously converge and track changes in the echo path to
support full duplex operation during double-talk situations.
