- Problem solved
- OpenAL was created to provide a vendor-neutral, cross-platform API for 3D audio, akin to OpenGL for graphics. Before OpenAL, developers creating games or applications with advanced audio often had to write platform-specific code for DirectSound on Windows or use various proprietary libraries, making multi-platform development challenging, inconsistent, and limiting the fidelity of interactive sound experiences. It sought to abstract away the underlying audio hardware, offering a consistent programming model.
