Nice to know something I did 30 years ago is still worth ripping off :-) These are probably ok at 96 or 192, but at 44.1/48 I think they will wander off at high frequencies due to warping. A better approach is to look for a solution which is symmetrical about fs/4. That version is only about 20 years old :-) Used with backwards dubbing gives partitioned convolution a run for its money. rgds, Geoffrey -------------- next part -------------- An HTML attachment was scrubbed...
