📝 About this app

1.What's Android USB type-C audio?

There are two ways to send audio data through the USB type-C port - Analog and Digital. Analog audio can be converted with an onboard DAC and amplifier inside your phone then sent out through the port to a passive set of headphones or an adapter. For this to work, the device needs to support whats called "audio accessory mode" and the headphones or adapter are just "dumb" connections that pass along the signal.

If you are using an active set of headphones or adapter, the audio signal being sent through the USB port is still in its digital form.… View full description on the official store →
