USB Audio Class 10 and 20 Devices:

USB Audio Class 10 and USB Audio Class 20 are specifications for USB audio devices that allow high-quality audio input and output over a USB connection. These classes are part of the USB Audio Class standards, which define how audio devices (such as microphones, headphones, soundcards, and speakers) communicate with a computer or other USB-enabled device. The USB Audio Class 10 and 20 are specific versions that describe newer features and capabilities for USB audio devices.

• USB Audio Class 10 (often associated with newer hardware) includes enhancements in power management, extended audio capabilities, and support for higher resolutions in audio playback and recording.
• USB Audio Class 20 (a newer version) expands on the features of USB Audio Class 10, adding even more advanced audio features, including support for higher bit rates, more audio channels, and improved audio synchronization. It is expected to become more widespread as it matures in the industry.

These standards are designed to be supported by both Windows and macOS operating systems, but you might need the appropriate driver for your specific device to work optimally with your computer.
