I was checking out the new features of Android and I stumbled across a bullet point for USB Audio. Additionally, from the Android website:
USB audio output support allows hardware vendors to build hardware such as audio docks that interface with Android devices. This functionality is also exposed with the Android Open Accessory Development Kit (ADK) to give all developers the chance to create their own hardware.
Is there some standard out there for audio data across USB? Can anyone point me to some references/specifications?
