Just to clear: I'm not experiencing Pd glitches at any configured audio setting whatsoever. What I mean is the abstractions produces 'wrong' results when configured to 64. I don't understand enough to give any hint why 128 is still fine and 64 sounds off. > Brent is not using gardner's approach I assume.

From what I gather without reading William Brent's [convolve~]'s source code, is that it uses n partitions with same size. At least the printed number seems to suggest that. Thus, using a smaller delay leads to a significantly increased CPU load. With Gardener's approach, the penalty of a short delay is almost not noticeable. Roman
