A 2-Way Loudspeaker Array System with Pseudorandom Spacing for Music Concerts
A 96-channel loudspeaker array system which allows real-time control of the sound field has been developed for musical live concerts. Multiple sound focuses at different points can be generated and controlled independently using the system. The variable delay circuits, the controller of the power amplifier and the communication circuit between the hardware and the computer are implemented in FPGAs. In order to extend the frequency range and reduce the spatial aliasing, the loudspeaker array is assembled by two-way loudspeakers with pseudorandom spacing.
