Reuploaded bigger screenshots. Yes, the low end seems more saturated, i think it depends on the plugin.

On what type of sources did you use oversampling?
I also noticed a brightness on the snare but not harsh.
You have to keep in mind that this is a development version and that some plugins will react differently to oversampling.

 

A 1176 adds harmonics on all the spectrum.

 

It depends on the project samplerate (44.1khz in my case).

 

I think they use the Voxengo r8brain algorithm for this now.

That is why it is in dev betas, not in rc/official.... It is still testing. Will be later. Maybe they prepare this for a 6.5 upgrade.... For synths this doesn't work.... Spire - silent in OS mode... Rob papen - glitches, stutters, pauses... Some synths leads to crash.... Vanguard (with no antialiasing mode in its plugin) works great.... So, it needs tweaking, testing...

 

Yep, see https://www.waves.com/support/tech-specs/sample-rate-support

 

Having the feature is Great,
now the Quality of the resampling is the point of the matter..

Will the Quality of this new FX/Chain oversample be dependent on the usual resampling setting?


Will 512 be enough? 768?
What would be the best balanced setting?

I guess having the Full Chain option is not that bad of a thing, considering the little artifacts could accumulate..
and well strictly speaking a 2x or 4x is already improving things considerably..

(also notice the "r8brain free" setting is Voxengo's open-source resampler,
here's a comparison tool with most popular software..)


In terms of Quality, how does this interpolation method compare to say DMG EQuilibrium's FIR,
which seems to be the top notch?



And since we're at it..
For a Non-Linear setting, how shall one read the Phase graph?
what does it mean in practical terms?

And what's the practical differences between the impulses,
what's the difference between using say a Blackmann-Harris window, vs a Kaiser window?

Is Reaper ever gonna get to that level and use FIR too?

to the first part and to the second, I'll show you ...

I have. You wrote

That's correct, but why is this process different in a plugin,

like you said here (underlined by me)

 

Interestingly, the Reaper OS looks a tiny bit cleaner (but probably inaudible)

 

Yes, i think there is a diference in the filter steepness.

 

Dave Gamble from DMG recommends to use Kaiser always. Because of good math. Other ones are just for testing, learning.

 

Yes,
see here

r8brain.
It's pretty fast considering it's the highest quality setting. So if your computer isn't from the early stone age, it's not a bad idea to set r8brain as playback resample mode in the project settings.

Apart from point sampling and linear interpolation settings, all other modes use an FIR filter.

A tiny bit cleaner+ 100000 tiny bits cleaner = Better Reaper and render.

 

For anyone interested in testing there plugins, watch this video from Dan Worrall.
You don't always need to use oversampling, but it's a good option to have.

I don't understand how Reaper is downsampling. So i have a 96Khz sine sweep that i processed with Fabfilter Saturn just to get some harmonics and then i made 2 renders one with the plugin in realtime downsampled to 44.1Khz and one with the processed 96Khz file reimported in Reaper and downsampled to 44.1Khz, and the results are diferent.

96Khz (no downsampling) render with saturn looks like this:



96Khz with saturn realtime downsampled to 44.1Khz:



Processed 96Khz file reimported in Reaper and downsampled to 44.1Khz:

 

96Khz with saturn realtime downsampled to 44.1Khz --- aliasing seems like 44.1kHz project used. As you see, no aliasing appears from sine above 22.05k, because processing with its aliasing hasn't been done, because everything above 22.05k (sine) wasn't there.

The latest screenshot is correct for true 96 to 44.1 conversion. Aliasing appeared from 22.05k and above, then converted.

 

The project sample rate is the same 96Khz. I think it should be the same result.

Maybe i didn't explained it well, so here is what i did.

I set the project sample rate to 96Khz, imported the 96Khz sine wave, inserted saturn, exported to 44.1Khz (first image), i exported a 96Khz file with saturn and after imported and rendered again to 44.1Khz (second image). Shouldn't it be the same result?

my thought exactly when i was reading thru the posts... someone tell me how oversampling creates a discernable difference of an audio source
