For small, cost-sensitive audio peripherals
- High performance
- Low power
- Low EMI
Stereophonic and surround sound
Low-latency multichannel audio transfer
MIPI SoundWire®, introduced in 2014, consolidates many of the key attributes in mobile and PC-industry 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.
MIPI SoundWire can coexist with MIPI SLIMbus or non-MIPI interfaces through bridging solutions.
The software component, MIPI DisCo Specification for SoundWire v1.0, is available to the public.
Note: The full specification is available only to MIPI Alliance members. For information about joining MIPI Alliance, visit Join MIPI.
