The MIPI Alliance exists to standardize widely used interfaces in mobile, such as those to cameras, displays, sensors, and more. I think MIPI originally stood for mobile industry processor interface when it was created, but now it says that "MIPI is not an acronym and has no specific meaning." The audio interface is called MIPI SoundWire and is intended to replace older approaches that present limitations to system designers in terms of power, pin-count, ease of integration, or lack of scalability. SoundWire is a digital audio interface specification, originally introduced in 2014, that can replace legacy audio interfaces, reducing the cost of supporting high-quality audio through reduced pin count, ease of integration, and low gate count. These system design benefits, and scalability of the solution from simple to high-end audio, make the standard attractive to many design applications.
