Improvements of Artificial Reverberation by Use of Subband Feedback Delay Networks

Document Thumbnail

This paper proposes the improvement of artificial reverberation through decomposition of input signal into subbands and use of different subband feedback delay networks (FDN). By this means nonuniform modal density is achieved and orders of FDNs are lowered. Evaluation of filter banks and corresponding subband FDNs are described. Comparison results, obtained through objective (simulation) and subjective (listening tests) analysis, are presented.
