Hello everybody! Sorry for my english. This is my recent project called ProjectF. This is sound engine based on OpenAL. Main emphasis is on sound effects, like a reverb and sound environment. The main idea - 'zone'. What is 'zone'? Zone is a AABB( axis-aligned bounding box ) or sphere, which uses one of 110 reverb presets. Also you can control air wetness in each zone to create realistic effect in propagation of sound. And second idea is obstacles.
Just listen this
And download the demo and the engine in attachment.
