MIPI SoundWire®, introduced in 2014, consolidates many of the key attributes in mobile and PC audio interfaces, providing a common, comprehensive interface and scalable architecture that can be used to enable audio features and functions in multiple types of devices and across market segments. It supports the use of advanced amplifiers and microphones. In addition, it can also optimize speaker protection, microphone power and performance, noise cancellation and always-listening audio input.
MIPI SoundWire is developed by the MIPI Audio Working Group.
MIPI SoundWire’s key features include a double-data rate, configurable frame size, low complexity, low power, low latency, optional multilane extensions, PCM and PDM format, multichannel data and a low gate count. It can be embedded in small, cost-sensitive audio peripherals such as amplifiers and microphones. It is also used in smartphones, tablets, PCs, automotive and embedded systems.
