Introduction

OpenAL (short for Open Audio Library) is a library for creation of a virtual 3D world of sound. The application programmer can specify the location, the speed and the direction of the sources of sounds and of the listener. This is easily combined with a 3D world created with OpenGL and can very well be used to create games. The sounds must be provided in the form of samples; there is no support for MIDI.

An addition to this library is the OpenAL Utility Toolkit (ALUT). See also the Wikipedia article on OpenAL.


Installation


Windows specific actions

Before installing the Haskell package, you need to install the C++ package of OpenAL:

where OpenAL32.dll
(You will need this later, when you distribute your application.)
Set LIBRARY_DIR=C:\Libraries
Set C_INCLUDE_PATH=%LIBRARY_DIR%\openal-soft-1.16.0-bin\include
Set LIBRARY_PATH=%LIBRARY_DIR%\openal-soft-1.16.0-bin\libs\Win32
If you need these variables more often, set them permanently.

For all platforms

Give command cabal install OpenAL

Tutorials

There are several OpenAL tutorials for other programming languages:


Examples


Additional software

  • StateVar: This package contains state variables, which are references in the IO monad, like IORefs or parts of the OpenGL state
  • ObjectName: Explicitly handled object names. This tiny package contains the class ObjectName, which corresponds to the general notion of explicitly handled identifiers for API objects, e.g. a texture object name in OpenGL or a buffer object name in OpenAL
  • Tensor This package contains tensor data types and their instances for some basic type classes.
  • OpenGL 3D graphics software
