OpenAL – What is it? and How to Download

What is OpenAL?

OpenAL Logo

OpenAL stands for Open Audio Library but it is actually a non-open source Application Programming Interface used to Render three-dimensional multichannel audio. This API is mostly used in the game and other audio application development using simulation techniques to add realism by adding attenuations, material densities, and Doppler effect. This platform is focused to become an open-source API network and eliminate the traditional 3d audio systems such as A3D and EAX.

How do OpenAL works?

The general operation of OpenAL is combined into three mediums listener, source object and buffer. The source object defines the position, velocity and direction of the sounds pointing toward the buffer. The listener object includes the position, velocity and listener directions. Buffers have the audio data stored in PCM format in either stereo or mono channels. Then further, the rendering is done by the dedicated rendering engine to do all the required calculations like attenuation, doppler effects etc.

The output is the sound behaving naturally as the user moves in the 3d world or space in the virtual world. The OpenAL specifications include two sections of API. First one is the core which consists the real OpenAL function calls. And the second one is Audio Library Context ALC API which is used for the rendering purposes. Just like OpenGL’s GLUT, OpenAL also has Audio Library Utility ToolKit (OpenAL ALUT) by which it gives higher levels of convenient functions to the developers.

Fix unable to initialize OpenAL probable cause: OpenAL not supported

This problem occasionally occurs in Minecraft when we launch it and it comes with no audio issue. Sometimes there is an error message of ‘OpenAL not supported’. The possible and most practical way to solve this problem is given below.

  1. You must get an advanced logger to look up the JAVA files.
  2. Find out the .dll file by going to the location C:\MyGames\Minecraft\profiles\Default\OpenAL64.dll
  3. If you do not find this file there then you have to download OpenAl.dll from 1.13 native libraries and then rename it to OpenAL64.dll.
  4. Drop this file into the same folder from the path given above.

If this method did not work, try reinstalling the openAL software again from the official website.

Fix could not locate OpenAL library Minecraft

Many times Minecraft comes with another type of error with a screen telling ‘could not locate OpenAL library’. The possible reason for this problem is that the audio library from the buffer to the listener is not getting fetched by the source files.

To get this issue fixed, you have to put both OpenAL32.dll and OpenAL64.dll into the project library. While making the executable jar file, use the Java code given below.

System.setProperty(“org.lwjgl.librarypath”, new File(“natives/windows/”).getAbsolutePath());

Try updating your OpenAL application once you are done with this method.
