These algorithms are incorporated into a Council to minimize the environmental impact of electrical equipment. powerful DSP platform that allow the user to extract intelligible information from the audio environment. Microsemi AcuEdge Technology The Microsemi AcuEdge Technology ZL38060 device ZLS38060 Firmware is designed for applications of the connected home. Its license-free, royalty-free intelligent audio Firmware Full Narrowband and Wideband Acoustic Echo (ZLS38060) provides Acoustic Echo Cancellation cancellation operation (AEC), Noise Reduction (NR) and a variety of other Supports long tail AEC (up to 256 ms) voice enhancements to improve both the intelligibility Non-Linear AEC provides higher tolerance for and subjective quality of voice in harsh acoustic speaker distortions environments. Non-Linear processor Microsemi offers additional tools to speed up the G.168 Line Echo Canceller product development cycle. The MiTuner ZLS38508 or ZLS38508LITE GUI software packages allow a Howling detection/cancellation user to interactively configure the ZL38060 device. Prevents oscillation in AEC audio path The optional MiTuner ZLE38470BADA Automatic Advanced noise reduction reduces background Tuning Kit provides automatic tuning and easy control noise from the near-end speech signal using for manual fine tuning adjustments.
