"GROM Audio announces USB audio steaming for Android Jelly Bean devices, giving users the best possible sound quality for in-car listening.
GROM is the first and only car audio company to deliver fully digital audio connection from any Android Jelly Bean devices (via USB2P or MST3P interfaces) to many factory car stereos. The direct USB Digital Audio connection provides high-quality sound, making a huge impact on Android users in-car media experience.
"The majority of car audio sound systems and radios will not allow high fidelity sound through wireless Bluetooth or aux-in, which was the main reason for developing direct Android USB Audio connection. Connecting audio digitally allows the music signal to remain in a digital form until it gets converted into an analog signal at amplifier or DAC; meaning no unnecessary manipulations are made to the signal on the way to your ears."- GROM Audio
GROM's direct USB Digital Audio connection via the GROM-USB2P adapter is the best way to get high quality sound in the car. Android users (Jelly Bean onwards) can play any music app including Pandora, SoundCloud and others to listen to their music library via the USB Digital Audio connection."
An Android Jelly Bean-powered smartphone/tablet can have:
. an Android-specific USB audio out capability (or USB audio accessory capability), or/and
. a standard USB audio out capability (or USB audio host capability)
An Android Jelly Bean-specific USB DAC acts as a USB host, and an Android Jelly Bean smartphone/tablet acts as a USB peripheral.
The Android-specific USB DAC acts as a USB host, and provides power to the Android Jelly Bean smartphone/tablet.
A standard USB DAC compatible with PC / Mac acts as a USB peripheral, and a PC / Mac / OTG-capable Android smartphone/tablet acts as a USB host.
The USB host provides power to a bus-powered USB DAC.
The USB host doesn’t provide power to a self-powered USB DAC.
A standard ACA-capable USB DAC could provide power to an ACA-capable USB host.
