    Abstract:

    In order to improve the limitation of the number of delay lines in the existing feedback delay network method and the inability to determine the sub-band reverberation time,this paper introduces a feedback delay network for artificial reverberationbased on the Householder feedback matrix and Butterworth filter bank.The Householder feedback matrix can maximize the echo density,the choice of delay lines number is relatively free.The Butterworth filter bank is convenient for specifying the sub-band reverberation time.In the simulation experiment,the validity of the proposed method wasverified by spectrogram,perceptual evaluation of speech quality,and subjective evaluation.
