Today's digital audio and voice market is more prosperous and diversified than ever before. A good audio product or edge intelligent voice solution may be warmly welcomed by global end consumers or system design manufacturers. However, to capture opportunities in the global market, it is necessary to develop platform products based on the most popular, flexible and easy-to-develop transmission protocols and core components, while leaving enough flexibility for the specific needs of the product for the market segments or regional markets, as well as fast differentiated product development time.

In terms of protocols, the USB transmission protocol originated from the PC platform has long been widely used in audio applications including voice and music, and has been applied to new applications such as new telephone systems, conference systems and human-machine interfaces developed based on PCs and emerging edge intelligent systems in recent years, thus becoming an important driving force for the audio market. From the perspective of ensuring audio quality, the bandwidth that USB connection can provide is far higher than the audio demand. It can support audio data and transmission with high-quality features such as high sampling rate, high encoding rate and multi-channel. Therefore, USB connection can be used to support traditional audio functions such as phone calls, music playback, recording, etc., and its convenient connection is widely used in voice-based intelligent human-machine interfaces in home appliances, cars, offices and other scenarios.

Now, more and more audio devices and smart devices are using USB connections and multi-channel audio solutions. As a product architect, you need to choose a high-performance and high-flexibility audio processing solution, and then you can start designing and producing a new generation of high-quality USB audio devices. XMOS's flexible microcontrollers are ideal for rapid product design and innovation in professional multi-channel audio and consumer high-resolution USB audio markets. Whether you need audio playback, recording, or both, the company's multi-channel and USB audio solutions can get perfect audio on time from multiple inputs.

The xcore®.ai multi-channel audio platform supports a wide range of consumer and professional audio products, providing a scalable and flexible hardware and software solution
