Title: Using filters with hires files... at their native rates Post by: manisandher on March 25, 2018, 02:20:34 pm Peter, I would have expected a 24/176.4 file being played back at its native rate to sound the identical, irrespective of which filter was selected in XX. But this does not seem to be the case.
Is there something I'm not appreciating about how the filters in XX work? Mani. PS. Will try 2.10 after Mansr's visit here tomorrow (don't want to risk screwing anything up beforehand).

Good question ... I am sitting back here for 5 minutes, but have yet to come up with an answer ... Because of that I'll need to look in the program and trace down what happens in which situation, but one answer would be that Custom applies the filter regardless, hence as not being part of the upsampling step (Arc Prediction itself does) - but which does not explain the difference between Nothing and Arc Prediction. That is, I must take it that between these two latter you also perceive a difference.

Yes, there seems to be a [quite large] difference between Nothing and Arc Prediction, which surprised me and hence why I thought to ask the question. I suppose it's academic really, as there's very little need to play hires back natively. I'll be doing this tomorrow though, as I'll be using a 176.4/192-capable DAC. I'll definitely set the filter to Nothing, as it sounds better with the 24/176.4 file I'll be using. [I found this also with the NOS1, playing some DXD files natively a while ago.] Just interested in knowing what's happening... Mani.

But this does not seem to be the case. I'm somewhat confused by this statement. I would expect a difference in all 3 states. Filters definitely change the sound. I tried this last evening with a 1 x 24/44HD track. Interesting in the light of 2.10 and new settings. I found Custom filter almost distorting. Arc Pre less so and no filter very clean sounding. This is pretty basic as I did not spend much time on this, as sound is renewed anyway. Certainly an audible difference between 3 states. In listening to Mark Knopfler's Privateering 24/96 its never sounded better with Arc Pre on. I have no final conclusion yet and have stayed with ArcPre for now. I do listen to a lot of Hires tracks these days from 24/44 to 24/352. You certainly have raised an issue Mani.

When the input is 24/176.4 and the output is set to the same, I'd say that Arc Prediction shouldn't do a thing. There just is nothing to do (Custom works differently, though). But there's always this "Volume" issue and if it is related to that indeed, I won't be able to find it. Checking for whether Arc Predition indeed does nothing is easy. So I should do that soon ...
