The sole reason for digitizing at 96 kHz assumes the signal bandwidth is no higher than 20kHz and thus well below the Nyquist frequency of 48 kHz and therefore minimize aliasing of any artifacts. I like that frequency better than 44.1 kHz because it is more likely compatible with Bluetooth as a couple of mine will not deal with 44.1 when using WASAPI on a Windows computer unless the music player (I use foobar) is set up to re-sample on the fly. With Audacity (which does 32-bit floating point processing), standard stuff like DC removal, normalization, channel balance, and maybe high pass if necessary to remove turntable rumble can be done before spitting out 16-bit/48kHz FLAC files (good enough for my ears). I already know the sound card/computer/software combo is capable of grabbing that signal without gaps or burps. My current plan is to digitize at 24-bits/96kHz (the best the Scarlett can do), and capture that using Audacity on a fast gaming computer (I have an Alienware laptop). I have been tinkering with how best to rip vinyl when using a phone preamp (I have an Emotiva XPS-1) between the turntable and an external sound card (I have a Focusrite USB Scarlett 2i4). My basic question is do I need a separate low-pass filter between my phono pre-amp and digitizing soundcard?
