If you ever stumbled across the http://src.infinitewave.ca/ site that is often linked you´ll see that phase-errors are a non-issue. Or do you mean something different? With todays linear phase filters you only have to decide how much it "rings" while that ringing is happening above 20kHz only or how much it allows aliasing back in the audioband. At best aliasing is only happening above 21Khz and therefore allows a slower filter that has less ringing. Ringing is the pre-echo that happens above the lowpass freequency but is a beloved term or showing a pic to show the evils of resampling. Here the suggestions what sounds best are very misleading. One brand suggest that one, the other one that has a patent for some kind of filter of cause suggests its one. Every self-proclaimed audiophile hears some strange non-linear filter best and so on... I think with 44.1kHz it is best to give up everything above 20kHz and use a linear filter starting at 20kHz and allowing aliang above 20kHz. No one will hear if that noise above 20kHz is alias or music :) One nice experiment is to take the Hires recording of your choice and apply such a lowpass to it without changing any sampling- or bitrate. Save that and compare. -- Wombat Transporter (modded) -> RG142 -> Avantgarde Acoustic based 500VA monoblocks -> Sommer SPK240 -> self-made speakers ------------------------------------------------------------------------ Wombat's Profile: http://forums.slimdevices.com/member.php?userid=4113 View this thread: http://forums.slimdevices.com/showthread.php?t=89733
