All-pass filters have been a central building block in artificial reverberation systems. The authors propose nested and interleaved combinations of such filters as an efficient way to produce reverberation architecture without a correspondingly high compute cost. The resulting dual all-pass filter approach compares favorably to that of embedded all-pass filters.
