AB  - We have been developing an effector which uses a 128-channel two-way loudspeaker array system for live concerts. The system was designed to ealize the change of the sound field within 10 ms. The variable delay circuits and the communication circuit between the hardware and the control computer are implemented in one FPGA. All of the delay data which have been calculated in advance are stored in the SDRAM which is mounted on the FPGA board and only the simple command is sent from the control computer. The system can control up to four sound focuses independently.
