# OpenSL-ES-Registry The OpenSL-ES-Registry repository contains the OpenSL ES API Registry, including specifications and headers. It is also used as a backing store for the web view of the registry at https://www.khronos.org/registry/sles/ ; commits to the main branch of this repository will be reflected there. **NOTE**: as of 2021-07-21, the default branch of this repository has been renamed from 'master' to 'main'. In the past, the OpenSL ES registry was maintained in a public Subversion repository. The history in that repository has not been imported to github, but it is still available at https://cvs.khronos.org/svn/repos/registry/trunk/public/sles/ . Interesting files in this repository include: * index.php - toplevel index page for the web view. This relies on PHP include files found elsewhere on www.khronos.org and so is not very useful in isolation. * api/ - OpenSL ES header files * specs/ - OpenSL ES specification documents. ## Adding Extension Specifications At present there are no extensions defined for OpenSL ES, and no process for extending it.
