SoundWire is a specification by the Mobile Industry Processor Interface (MIPI) Alliance that describes a unified interface for audio peripherals.
It defines a two wire multidrop bus that allows up to 11 peripherals to be connected to a manager.
Electrical characteristics
[edit]The bus consists of a stretchable clock, between 3MHz and 12.7MHz, and data wires that use double data rate signaling to provide up to 25.4Mbits/s.
Each peripheral can provide up to 8 audio channels
