Download MIPI SoundWire Device Class for Audio Specification
A standardized interface for software to control audio functions of devices that use MIPI SoundWire
The MIPI SoundWire Device Class for Audio (MIPI SDCA™) specification facilitates the development of generic SoundWire® software that can provide audio functionality using the native operating system "out of-the-box" without being dependent upon the availability of device-specific or system-specific software.
MIPI SDCA is applicable to any SoundWire audio system topology that uses either MIPI SoundWire or the forthcoming MIPI SoundWire I3S (MIPI SWI3S™) as the interface for transporting audio payload and related control information.
The version available to download here (v1.1, adopted July 2025) updates SDCA to include several new features: simple jack, simple microphone, simple amplifier and network digital audio interface for Bluetooth/display devices. It also improves support for autonomous ultrasound sensing and resolves issues and corrections identified in the previous version. In addition, MIPI DisCo (Discovery and Configuration) content has been integrated directly into the SDCA specification.
