    PSoC 4 Pioneer Kit Community Project#102 – USB Audio using the PSoC 5LP



      In today’s example we are including a demonstration project for supporting Audio playback and audio recording using USB digital audio. The PSoC 5LP communicates with any USB host, provides a high-quality recording interface to it, and extras high-quality digital audio from the USB host. In this example we show the PSoC 5LP device communicating to:

      • Windows
      • Mac
      • Linux
      • Android
      • Raspberry Pi
      • BeagleBone Black
