- Specification history: The OpenAL specification defined the API and behavior; multiple implementations followed. The original OpenAL had extensions for features like EAX (Environmental Audio Extensions) for reverb and occlusion, often provided by hardware vendors.
- Hardware vs. software: Early adopters frequently relied on hardware acceleration from sound card vendors. Over time, hardware support waned and software implementations grew more important.
- OpenAL Soft: A widely used open-source software implementation, OpenAL Soft reimplemented the API with modern features, portability, and better audio quality, becoming the de facto reference for many platforms. It supports advanced features: HRTF-based 3D audio, multichannel rendering, effects, and high-quality resampling.
