Timberwolf Digital Signal Processor family, powered by AcuEdge™ Technology Advanced Multi-Channel Super Wideband Audio Processor ZL38042 Preliminary Data Sheet 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 from which they are communicating. The ZL38042 device supports 4 digital microphones and provides advanced Acoustic Echo Cancellation (AEC) and non-stationary Noise Reduction (NR) for up to 3 parallel microphone paths for Super Wideband conference phone applications.
