ZL38050 Datasheet | Microsemi

Description The ZL38050 is part of Microsemi’s new Timberwolf audio processor family of products that feature the pany’s innovative Acu Edge acoustic technology, which is a set of highly-plex 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 Microsemi Acu Edge Technology ZL38050 device is ideal for IP and security camera applications. Its license-free, royalty-free intelligent audio Firmware (ZLS38050) provides Acoustic Echo Cancellation (AEC), Noise Reduction (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 Mi Tuner™ ZLS38508 or ZLS38508LITE GUI software packages allow a user to interactively configure the ZL38050 device. The optional Mi Tuner ZLE38470BADA Automatic Tuning Kit provides automatic tuning and easy control for manual fine tuning adjustments.
