Circulant Feedback Delay Network(CFDN), whose feedback matrix is circulant to control the stability of system and time-frequency response easier than unitary one, were recently proposed. However, the drawback of this structure is that the flatness of frequency response of CFDN is not enough and it is difficult to adjust position of zeros to decrease this problem.
Therefore, we represent the usefulness of CFDN to build artificial reverberators and the main parameter to determine characteristics of CFDN in this paper.
