Audio specification of usb type port released

The USB Type-C connector has the great advantage of being multipurpose since it allows transmitting a large amount of information from data to audio, video or power. For this it is necessary that there are some official specifications to avoid having to use adapters, exactly as it happens in other ports such as HDMI or Displayport.

Audio Device Class 3.0 is the audio specification for USB Type-C

The body in charge of regulating the USB Type-C specifications has just published the final specification of Audio Device Class 3.0 to add the connector to the official formats of audio transfer, with this movement we will be able to see headphones and other sound devices that make use of the USB Type-C port to transmit the audio, without a doubt a step ahead for the removal of the 3.5 mm jack connector from our smartphones and tablets, something that is already becoming fashionable.

The new audio specification for USB Type-C is compatible with analog and digital audio signals so it will be very easy to implement sound through this port. In the case of the analog signal, practically no electronics will be needed to convert 3.5 mm jack to USB Type-C, in the case of the second, the specification defines the operation of the circuitry that needs to be integrated into the headphones and that It will deal with the different signals and the synchronization between the devices such as audio conversions, noise cancellation, equalization, volume controls and others.

By converting from digital to analog in the same headphones , the quality loss due to compression that is usually present in headphones that use other technologies such as Bluetooth is avoided.
