New Spec for Audio over USB Type-C

The USB Implementers Forum (USB-IF) announced a new USB Audio Device Class 3.0 specification to establish USB Audio over USB Type-C as the primary solution for all digital audio applications, including headsets, mobile devices, docking stations, gaming set-ups and VR solutions.

“USB is the simplest and most pervasive connector available today, making USB Type-C the logical choice for the future of digital audio,” said Jeff Ravencraft, USB-IF President and COO. “We encourage companies interested in adopting USB specifications to take advantage of USB-IF resources to reduce time-to-market and deliver reliable USB products.”

The USB Audio Device Class 3.0 specification makes it easier to support digital audio over USB, add capabilities to reduce power consumption and add support for new features such as hotword detection. It defines minimum interoperability requirements across analog and digital solutions to minimize user confusion when not all hosts or devices support audio consistently. USB Audio over USB Type-C™ allows OEMs to remove the 3.5mm analog audio jack, shaving up to a millimeter off product designs and reducing the number of connectors on a device. Fewer connectors will open the door for innovation in countless ways and make it easier to design waterproof or water-resistant devices.
