Introduction

The XVF3800 is a high-performance voice processor optimized for voice communications. It uses microphone array processing and an advanced audio processing pipeline to capture clear, high-quality speech from any position in a room. Based on the xcore.ai processor, the device supports a range of integrated and accessory voice communication applications. The XVF3800 is a highly customizable design that integrates the processor and application firmware into a single solution, providing system designers with the flexibility to integrate into different designs. The powerful architecture of the xcore.ai processor delivers high-performance, real-time audio processing, while the XVF3800 firmware is designed for easy customization, allowing users to modify it as needed. In addition to audio processing capabilities, the XVF3800 includes a range of standard interfaces that enable it to connect to a variety of devices. It supports a simple and intuitive control interface, allowing designers to quickly and easily configure the system and perform common tasks. In most applications, the XVF3800 device will work in conjunction with an external host processor.
