OpenAL (Open Audio Library) is a cross-platform audio API designed for rendering multichannel 3D positional audio. It is intended for use in various audio applications, especially within the gaming industry, to provide a rich audio experience by delivering spatial audio effects. OpenAL works similarly to OpenGL, but for audio data, enabling users to create and manipulate sound in a 3D space. It is available on multiple operating systems, making it a versatile choice for developers seeking consistent audio playback across various platforms.
