Editor's review OpenAL SDK
OpenAL SDK includes documentation, sample code, demo applications, and a re-distributable run-time installer. It includes the X-RAM Extension, the Effect Extension (EFX), Multi-Channel Buffer playback extension, and a new Device Enumeration extension that allows AL to be rendered on any installed soundcard / audio end-point. It's a cross-platform 3D audio API designed for use with games and other types of multimedia applications. It features an extension mechanism allowing its vendors to add new features to the library. Creative Labs has added a number of extensions including EAX and X-RAM. Effects Extensions introduce a number of new objects: Auxiliary Effect Slot object represents an effect that can be fed with a mix of audio from selected Sources. Effect Objects consist of the parameters required to define an Auxiliary Effect. Filter Objects contains the information needed to set up a filter. Different OpenAL devices may support different effect types.
