Sound Open Firmware (SOF) is a permissive licensed open source audio DSP firmware and SDK that provides infrastructure and tools for audio DSP developers.

This presentation will tell the story of how Intel took a historically closed source firmware with a proprietary SDK and created an open source firmware with opensource SDK. It will also describe the technical and non-technical challenges that had to be overcome in releasing open source audio firmware and creating a free SDK.

Finally, the presentation will provide technical information about architecture, tooling and how to get involved.
