Description
The ZL38090 is part of Microsemi's Timberwolf audio
processor family of products that features Microsemi’s
innovative AcuEdge™ firmware, which uses a set of
highly-complex and integrated algorithms designed for
audio enhancement. These algorithms are incorporated
into a powerful DSP platform that allows the user to
extract intelligible information from adverse audio
environments.
The Microsemi AcuEdge Firmware for the ZL38090
device is specifically designed for USB headset and USB
microphones. The ZLS38090 AcuEdge firmware is
royalty-free and provides an advanced audio feature set
including beam forming (BF), noise reduction (NR),
equalizers (EQ), and a compressor, limiter and expander
(CLE) 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 ZL38090 device. The optional
ZLE38470BADA Automatic Tuning Kit provides
automatic tuning and easy control for manual fine tuning
adjustments.
