Wave Field Synthesis is a spatial audio rendering technique that places virtual sound sources in real space. The system is modeled after the array designed and built at EMPAC. It can place sound sources accurately in physical space in front of the speakers -- in short, it makes sound holograms or "holophones." The array has 372 individually addressable channels and uses IRCAM's Spat suite within Max. The boxes are modular and are usually set up as two 186-channel arrays (~38 The synthesis is precise and physically correct. You cannot distinguish the synthesized source from a “real” wave field at frequencies below the upper frequency limit of the system. The system allows for undistorted wave field generation up to the spatial aliasing frequency of 3.3 kHz, and experimental configurations for testing the perceptual effects of frequencies between 700 Hz and around 6 kHz.
