The GOWIN UAC (USB Audio Class) to I2S Audio Card Reference Design provides an example of using various IPs to play and record Audio from a PC using GOWIN FPGAs. The reference design connects GOWIN Semiconductors USB 2.0 PHY, Device Controller, I2S RX and TX IP Cores as well as provides some basic control logic via USB HID (Human Interface Device). This provides a starting point to develop ...
A very successful application space for USB continues to be audio. From basic USB speakers to high-resolution audiophile headphone amplifiers, and from a USB microphone to a multi-channel mixing and recording desk, USB connectivity has enabled a rich and diverse range of audio products. Behind this success is the USB Audio Class (UAC) standard, which defines an extensive and robust set of ...
UAC/UAD defines the implementation and control functions of devices that implement audio under the USB specification. These functions include not only the digital part of the audio, but also the analog part. These audio data (analog and digital) and are used to directly control the functions of the audio environment, such as volume and tone ...
