Description
The ZL38042 is part of Microsemi’s new Timberwolf
audio processor family of products that feature the
company’s innovative AcuEdge acoustic technology,
which is a set of highly-complex and integrated
algorithms. These algorithms are incorporated into a
powerful DSP platform that allow the user to extract
intelligible information from the audio environment.
The ZL38042 device supports 4 digital microphones
and provides advanced Acoustic Echo Cancellation
(AEC) and stationary Noise Reduction (NR) for up to 3
parallel microphone paths for Super Wideband
conference phone applications. For additional mics, a
ZL38042 device can be configured as a master to
control up to 4 slave ZL38042 devices.
The Microsemi AcuEdge Technology license-free,
royalty-free intelligent audio Firmware provides AEC,
NR and a variety of other voice enhancements to
improve both the intelligibility and subjective quality of
voice in harsh acoustic environments.
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 ZL38042 device.
The optional MiTuner ZLE38470BADA Automatic
Tuning Kit provides automatic tuning and easy control
for manual fine tuning adjustments.
