OpenAL (Open Audio Library) is a cross-platform audio application programming interface (API). It is designed for efficient rendering of multichannel three-dimensional positional audio. Its API style and conventions deliberately resemble those of OpenGL. ZDoom can use its free software implementation, OpenAL Soft, with libsndfile and libmpg123 as file decoding backends.
