USB Audio

USB Audio is the industry standard for transmitting high-fidelity digital sound between host devices and peripherals like the Focusrite Scarlett or Sennheiser HD series.

USB Audio leverages specific Device Class definitions (ADC 1.0, 2.0, and 3.0) to bypass noisy internal computer circuitry and deliver clean data to external DACs. Version 2.0 is the current pro-audio benchmark: it supports 24-bit/192kHz sample rates and asynchronous synchronization to eliminate clock jitter. This protocol powers everything from plug-and-play Shure MV7 microphones to complex 64-channel studio interfaces. By utilizing standardized drivers (UAC), it ensures low-latency performance across macOS, Windows, and mobile hardware without requiring proprietary software for basic operation.
