Wave field synthesis (WFS), pioneered by Delft Technical University, has been around as a research topic for around 15 years. With the implementation of a large WFS array in the Ilmenau cinema, new applications for WFS technology are around the corner. The paper gives an introduction to basic WFS theory, explains major application areas including cinemas, concert halls and music performances (indoor and outdoor) of all kinds. For larger WFS arrays, some new problems had to be solved. Current designs allow better audio for large audiences including virtual sound sources at perceived locations inside and outside the array perimeter.
