Features:_x000D_
USB sound is an USB audio controller. It supports 32KBz, 44.1khz.(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._x000D_
In digital playback mode, it receives audio stream from PC via USB interface and transmits audio data according to the AES/EBU,IEC60958,S/PDIF consumer interface standards. Only R, L channel PCM audio in 5.1 channel can be conveyed in digital playback mode. In analog playback mode, it supports 6 channels codec for analog playback._x000D_
In digital recording mode, it receives S/PDIF digital audio input and sends back to PC through USB. Three sampling rates; includes 32KHz, 44.1 KHz are automatically locked internally, in analog recording mode, fixed 48KHz sampling rate is supported by analog audio recording._x000D_
