AB  - We developed an artificial reverberation device based on a novel, time-variant orthogonal matrix feedback delay network topology. Our novel topology uses multiple, time-variant output taps for each delay line, and therefore simultaneously reduces the amount of delay memory required without introducing coloration, and increases the echo density. Furthermore, the system is guaranteed stable provided that certain constraints on the delay line lengths and tap weights are fulfilled. Our implementation on a 24-bit digital signal processor requires only 16384 words of delay line memory for a four channel input / four channel output reverb.
