Citation :Comments on filters. The traditional filter with pre and post ringing is fine. The ringing only occurs in the transition band. Audiophiles got bent out of shape about nothing seeing the graphs and not understanding them. The transition band is from 20 khz and the 22.05 khz cutoff for CD. So you'll not hear it.

This created a marketing opportunity to sell something as different and Superior. People created filters that ring only after the pulse. Or ring less time after the pulse. This usually would cause the upper octave response to droop some. And/or let aliasing artifacts thru. That might seem to beef up the detail with some music. Technically most of these filters are less correct than the traditional type.

As already mentioned the fashion is softer treble is more analog like. And some of these filters sound different which was pushed as being Superior.

Search for the xiph.org Digital show and tell video. It is very educational and easy to understand.

Et donc en résumé un filtrage classique avec oversampling permet de rejeter le pre-ringing dans une plage de fréquence inaudible
