Intel Smart Sound Technology for USB Audio is a driver component that enables support for Intel Smart Sound Technology (SST), a platform feature designed to enhance audio processing capabilities for USB audio devices. This technology is often used in devices such as external USB sound cards, audio interfaces, or USB microphones that are powered by Intel processors.

Intel Smart Sound Technology is part of the broader Intel Audio family and is designed to offload audio processing from the main CPU to a dedicated audio DSP (Digital Signal Processor) for better performance, reduced power consumption, and enhanced audio quality, particularly in devices that handle real-time voice or sound data, like virtual assistants, gaming, or video conferencing apps.
