OpenSL ES Adoption and Conformance Testing

OpenSL ES Adopter Login

Any company may freely use the publicly released OpenSL ES specification to create a product, but implementations of the OpenSL ES API must be tested for conformance in the Khronos OpenSL ES Adopters program before the OpenSL ES name or logo may be used in association with an implementation of the API.

Implementers may join the Khronos OpenSL ES Adopters Program which enables them to download and execute the OpenSL ES conformance tests and upload the results for peer review within Khronos.  If the implementation successfully passes the tests, the Adopter is granted a royalty-free trademark license to use the OpenSL ES name and logo in association with that implementation - and they can refer to the implementation as being OpenSL ES conformant or OpenSL ES compliant.

Benefits of the OpenSL ES Adopters program:

  • Access to the OpenSL ES 1.0 conformance test source code
  • Participation in the OpenSL ES Adopters technical Mailing list - a private priority channel for two-way interaction with the OpenSL ES working group over the specification and conformance tests
  • Conformant products may use the OpenSL ES name and logo
  • Company listing on the Adopting Members and Conformant Products pages
