What software is openal?

openal is an API used for sound effect buffering and listening encoding. It is a cross-platform sound effect API in the free software world; the full name of openal is "Open Audio Library", which is used by "Loki Software" in Windows and Linux systems. On top of that, OpenAL is designed to provide special effects performance for multi-channel three-dimensional positional sound effects.

What software is openal

API used for sound effect buffering and listening encoding

OpenAL (Open Audio Library) is a cross-platform in the free software world Platform sound API, used by Loki Software on Windows and Linux systems, is used in sound buffering and listening encoding.

OpenAL is designed to provide special effects performance for multi-channel three-dimensional positional sound effects. Its API style is imitated from OpenGL.

If it is OpenGL, it is a cross-programming language and cross-platform programming interface specification for three-dimensional images (two-dimensional is also acceptable). OpenGL is a professional graphics program interface, a powerful and easy-to-call underlying graphics library.

Structure and function:

The main function of OpenAL is to encode in the source object, sound effect buffer and listener. The source object contains a pointer to the buffer, the sound's speed, position and direction, and the sound's intensity. The listener object contains the listener's speed, position, and direction, as well as the overall gain of all sounds. The buffer contains audio data in 8 or 16 bit, mono or stereo PCM format, and the presentation engine performs all necessary calculations such as range attenuation, Doppler effect, etc.

Different from the OpenGL specification, the OpenAL specification contains two API branches; the core composed of actual OpenAL functions, and the ALC API. ALC is used to manage presentation content, resource usage, and seal cross-platform styles in in. There is also the "ALUT" library, which provides high-level "easy-to-use" functions, and its positioning is equivalent to OpenGL's GLUT.
