The screenshots show the spectrometer while playing the file and the spectrum (in black & white sensitivity = content from -120db and above) of the upsampled file. I've upsampled a track with iZotope RX4 to 96kHz with your settings (5/1/1). But obviously I could easily be wrong about that.Here are 2 screenshots that make things a bit clearer. I did have a look at my filter settings in RX3 way back when, and from what little I knew (and know) they seemed to produce a reasonable graph. What about filter max length? Is it all the same for all the settings, what do you prefer? This is why I think it's pretty useless at low steepness settings and I would rather set the AA-filter to 100 or 50. It only suppresses freuquencies right AT the nyquist limit (see here for steepness: 5 / cutoff: 1 / AA: 200 / pre-ringing: 1 : ). The Anti-Aliasing filter in the iZotope SRC section of A+ does NOT help to remove aliasing/artefacts ABOVE the nyquist limit. Furthermore me personally I prefer upsampling by power of 2 (with all the settings noted above). I always set the max filter length 200.000. Personally I don't think that the filterlength really affects the sound (if so it's mostly likely related to computer-power.). But this goes for all the settings listed in this second section. Too, as outlined above, IMHO settings with such a low filter steepness are better used in conjunction with an appropriate high quality lowpass (highcut) filter in the AU plugin section of A+ if you want to upsample on the fly (and if you do so better set Anti-Aliasing to 50). So if you set the gain by default for instance to -3db you should set it to -4db with this setting. cutoff 1.3 requires to reduce the gain by 1db to avoid too high intersample peaks. super weak (actualy 'no') filter quality.My settings from above just to be listed again here. for me overall a really great compromise between filter quality & low ringing & low pre-ringing.soft rolloff of high frequencies (starting at 16kHz or so."proven" settings if you don't care about aliasing/artefacts above the nyquist limit (for whatever reason): good compromise between decent filter quality & moderate ringing & moderate pre-ringing."Safe" settings if you want to remove aliasing/artefacts above the nyquist limit: Since the files are now at 176.4kHz (192kHz respectively) the nyquist limit is so high that there is no need to shift the cutoff scaling or to apply any Anti-Aliasing filtering.Ī follow up of my previous post re "safe" settings. To further upsample these files to DSD in A+ I set the iZotope settings to almost the same values: steepness: 3, cutoff: 1, pre-ringing: 0.36, Anti-Aliasing: 50 (so the lowest value). I then remove all the aliasing/artefacts above the nyquist limit with said Fabfilter plugin in linear phase mode at the highest quality setting and save the files as 24bit TPDF dithered files. But before I started to convert my entire library I've further fine-tuned my SRC settings and am now at steepness: 3, cutoff: 1.3 (to preserve all high frequencies), pre-ringing: 0.36.

and afterwards removed all the aliasing/artefacts above the nyquist limit with Fabfilter Pro Q2. Actually I was really happy with steepness: 16, cutoff: 1, pre-ringing: 0.72.

Meanwhile, me personally I prefer offline upsampling (of 44.1kHz an 48kHz source files) in iZotope RX4. If you want to effectively remove aliasing/artefacts above the nyquist limit while upsampling on the fly and without using a plugin I would say "steepness" should at least be set to '31' or higher (and "Anti-Aliasing" to '200'). so you would have to manually change the plugin settings whenever the sample rate of the source changes (which is pretty cumbersome). If so, you would consequently need different EQ/Filter-settings for different source sample rates. If you prefer low steepness (at the expense of filtering quality) you can also filter out aliasing/artefacts above the nyquist limit with an appropriate EQ in the AU Plugin section of A+. lower steepness = smooth roll off of high frequencies (unless you increase "cutoff scaling")įrom these few notes alone you can see that we are always dealing with trade-offs/ compromises. lower steepness = better instrumental seperation (especially in complex, 'full' musical arrangements) higher steepness = better filtering above the nyqiust limit Minimum phase (low pre-ringing respectively) = better transients ("attack")

This is from the manual of HQPlayer and I agree: Some - personal! - notes regarding "rules of thumb".
