Preliminary Data Sheet
Description
The ZL38052 is part of Microsemi’s Timberwolf audio
processor family of products. These devices feature
Microsemi’s innovative
AcuEdge
acoustic technology,
which is a set of highly-complex and integrated
algorithms. The Microsemi
AcuEdge
Technology
ZL38052 is designed to provide leading edge far field
microphone processing with advanced features
targeted for IP and security cameras with high
definition (HD) 2-way hands-free voice.
The Microsemi
AcuEdge
Technology license-free,
royalty-free intelligent audio Firmware provides
Beamforming, Sound Location Estimation, Acoustic
Echo Cancellation (AEC), Noise Reduction and a
variety of other voice enhancements to improve both
the intelligibility and subjective quality of voice in harsh
environments. The ZL38052 also incorporates a sound
classification feature allowing the system to recognize
smoke detector alarms (T3), carbon monoxide
detector alarms (T4) and glass break detection.
Microsemi offers additional tools to speed up the
product development cycle. The
MiTuner™
ZLS38508
or ZLS38508LITE GUI software packages allow a
user to interactively configure the ZL38052 device.
The optional
MiTuner
ZLE38470BADA Automatic
Tuning Kit provides automatic tuning and easy control
for manual fine tuning adjustments.
