USB sound is an USB audio controller.It supports 32KBZ,44.1KHZ.(which two need driver or application software support) and 48KHZ sampling rate in digital recording,48KHZ sampling in analog recording and 48KHZ in digital/analog audio playback.

In digital payback mode,it receives audio stream from PC via PCB interface and transmits audio according to the AES/EBU,IEC60958,S/PDIF consumer interface standards. Only R,L channel can be conveyed in digital playback mode. In analog playback MODE,it supports 6 channel codes for analog playback.

In digital recording mode, it receives S/PDIF digital audio input and sends back to PC through USB. Three sampling rates,includes 32KHZ,44.1KHZ are automatically locked internally. In analog recording mode,fixed 48KHZ sampling rate is supported by analog audio recording.
