Ah, that is a shame. Ours could easily be turned into a stand-alone PD version but without identifying a modern need, it'd be busy work. My suspicion is that our lib is actually considerably faster than other implementations (single cpu, non simd), just limited in the kernel sizes it supports. But that's just a gut feeling based on how it's implemented. Maybe if we get back into signal processing more, we can brush the dust off. Thanks, Priit. Cheers!
