AB  - Wave field synthesis (WFS) is a sound field reproduction technology that assumes that the reproduction environment is anechoic. A real reproduction space thus reduces the objective accuracy of WFS. Adaptive wave field synthesis (AWFS) is defined as a combination of WFS and active compensation. With AWFS the reproduction errors are minimized along with a departure penalty from the WFS solution. Analysis based on the singular value decomposition connects WFS, active compensation, and Ambisonics. The decomposition allows the practical implementation of AWFS based on independent radiation mode control. Results of experiments in different rooms support the theoretical propositions and show the efficiency of AWFS for sound field reproduction.
