  • Computationally efficient multi-resonator reverberation
    Patent number: 8705757
    Abstract: A signal processor to produce a simulated reverberation effect based on an input signal and conveying the impression of multiple interconnected resonating spaces. A feedback delay network produces a reverberation tail signal, which is delayed by varying amounts in a delay module. A panning module produces a multi-channel signal based on the reverberation tail signal and its echoes.

  • Computationally efficient synthetic reverberation
    Patent number: 8345887
    Abstract: A digital audio signal processor uses a matrix transform to produce a multi-channel synthetic reverberation signal based on variably-delayed versions of an input signal. The matrix transform outputs are mixed with the inputs to the signal delaying mechanisms, and some of the outputs are further processed to create the reverberation signal.
