Wave Field Synthesis (WFS) and Near-field Compensated Higher Order Ambisonics (NFC-HOA) constitute the two best known methods for sound field synthesis. Due to the different formulations a comparison of the two approaches has only been possible with certain limitations. This talk presents a unified framework based on fundamental integral equations covering both WFS and NFC-HOA. The relationships of the two approaches are pointed out and emphasis is put on the properties of the synthesized sound fields with respect to spatial aliasing.
