AFAIK all filters which are not marked as apodizing in the HQPlayer filter table preserve original sample values. Only filters, which are marked as apodizing may change original sample values. Mostly it does not happen. @jlaako may confirm this ...Nearly every other filter -- apodizing or not -- does not share this trait. With those other filters, when you input a sample value x at audio stream position t, and you inspect that sample value t at the output (so awaiting the latency of the filter), the value is almost certainly not x anymore
Preserving original sample values is not specific only for closed form filters. Schiit mentions these because they implemented them in their product.
