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.
