The OpenSL ES standard simplifies deployment of hardware and software audio capabilities across any platform or operating system and provides broad audio portability for application developers. The specifications are immediately available for download at http://www.khronos.org/opensles/ and may be used royalty-free by implementers and developers. An Adopters Program for OpenSL ES including extensive conformance tests to ensure cross-implementation consistency and trademark usage by conformant implementations will be released by Khronos during April 2009.
The audio API space is highly fragmented and developers are forced to constantly port their audio code across proprietary or platform-specific APIs as even just playing a simple sound requires different code on different platforms. OpenSL ES fills a void in the audio API arena by enabling standardized, cross-platform access to a native platformâ€™s audio capabilities -- not something that APIs such as OpenAL or ALSA were designed to do, say the folks at Khronos.
OpenSL ES defines standardized access to both basic and advanced features such as MIDI playback and 3D positional audio on any device and operating system and is extensible by implementers to take advantage of emerging audio capabilities. OpenSL ES also provides a portable foundation for implementing the audio portions of higher-level APIs such as JSR 135 and JSR 234.
