Sound Open Firmware (SOF) is an open source audio Digital Signal Processing (DSP) firmware infrastructure and SDK. SOF provides infrastructure, real-time control pieces, and audio drivers as a community project. The project is governed by the Sound Open Firmware Technical Steering Committee (TSC) that includes prominent and active developers from the community. SOF is developed in public and hosted on the GitHub platform.

The firmware and SDK are intended for developers who are interested in audio or signal processing on modern DSPs. SOF provides a framework where audio developers can create, test, and tune the following:

• Audio processing pipelines and topologies.
• Audio processing components.
• DSP infrastructure and drivers.
• Host OS infrastructure and drivers.
