In this tutorial I create a simple sound manager class that can play back multiple sounds using OpenAL. It also allows you to play background music as well using the AVAudioPlayer class.
The reason for writing my own sound manager was to see how OpenAL works. Commenters on this blog provided some great links, see the “Sound of music… explosions and lasers”, so I decided to work through them and get something working.
This class is simple and provides basic access to playing sounds in OpenAL. It also makes use of all 32 sources OpenAL sources available on the iPhone so that the same sound can be played simultaneously which is great for explosions and laser fire.
