@jussi_laako Is there any chance that you will release an apodising version of the Sinc-L filter? It’s by far my favourite filter for clarity and vivid/punchy/“tactile” sound. Although I could switch to Sinc-S/M/M(x) when listening to songs containing lots of apodising errors (some go into hundreds/thousands!), none of them quite reach the level of Sinc-L in terms of the above-mentioned aspects of sound. It would be great to have an apodising version of Sinc-L, unless there’s a technical reason why this is not possible for this type of filter.
