What is USB Audio
USB Audio is a digital audio standard used in PCs, smartphones, and tablets for interfacing with audio peripherals. The source device that produces the data is called the USB host, and the sink is the USB client. So if a smartphone is connected to a computer, the computer is the host and the phone is the client. But if the DAC is connected to a smartphone, the phone is now the host and the DAC is the client.
Below we can see a Schematic diagram for USB audio, in order to realize the USB AUDIO function, we use an MCU USB peripheral to connect to the PC. The whole process is as follows: When the PC plays music, the data stream representing the music is transmitted from the PC to the MCU through USB, and the MCU The terminal then forwards it to an external Codec, and finally plays the music through speakers or headphones connected to the Codec.
