FR: over sampling display

[steve2KVR]

It would be helpful if the oversample indicator could/would indicate when it is not in use. Perhaps just a "0x" would suffice:

[Held]

Wouldn't 0x mean no samples? 1x is turned off.

[steve2KVR]

...mmmmm...my reading of the display is that 1x == 44.1 x 2 = 88kHz when "High-quality upsampling" is "On/highlighted" and that when "High-quality upsampling" is not highlighted that means nothing is applied...thoughts?.../s

[Held]

In your image, you've set the plugin oversampling to 2x (top right of your image), so 1x for the limiter module will be 2x of the daw's sample rate

[steve2KVR]

Well, I guess, that leads to two FR's then...
1/ the original request for a visual indication of status, and...
2/ some mention in the docs/etc that the two parameters are inter-related. I did know that was the case, and until you pointed it out I was operating under the belief they were not. I don't use over sampling in daily work, but was preparing some compositions for final delivery to a client. I thought I would try some experiments to see what would happen, good or bad. Thanx for the heads up.../s~

Now I am confused. For me was logical 1x = no upsampling. High-Quality upsampling is another kind of upsampling (interpolation type I assume).
I've also always wondered what happens when I change the upsampling in each module, is it multiplied by global upsampling or replaced?

[steve2KVR]

@Falky, I'm with ya'brother! I had assumed it was individual and final. We'll see what V has to say.../s~

[Held]

Wouldn't that be odd, though? If I set MSF to 2x48kHz, but every internal module only uses 1x48kHz by default, what's the point of the global setting?

The modules show the actual sample rate being used, so you can figure out what's going on.

[steve2KVR]

"Wouldn't that be odd, though?"...not sure about that. Any number of reasonable assumptions could be made in the absence of specific information about the processing signal flow and interactions. My initial assumption was basically "what you see is what you get," and that the individual modules processed the input signal independently of each other, in sequence, passing the results down stream to the final processing at the output. However, your observation suggests otherwise...so now, I'm not sure.../s~

[Held]

The way I see it, every plugin (let's assume MXXX) uses the DAW's sample rate (let's assume 48kHz) by default.

Code: Select all

-48kHz-in->[48kHz*1-MXXX-48kHz-out-]->

If you use 2x oversampling, the sampling rate gets doubled after coming into MXXX and halved before it leaves.

Code: Select all

-48kHz-in->[48kHz*2-MXXX-96kHz/2-out]->

When you add a module inside MXXX without it's own oversampling, it makes sense to me that it just uses the given input without changing it. Let's assume it's a limiter.

Code: Select all

-48kHz-in->[48kHz*2-MXXX->[96kHz*1-Limiter-96kHz]->96/2kHz-out]->

If you enable oversampling in the limiter, it uses the MXXX's sample rate as the base (1x) and multiplies it with whatever you select.

Code: Select all

-48kHz-in->[48kHz*2-MXXX->[96kHz*2-Limiter-192kHz/2]->96/2kHz-out]->

What you seem to be suggesting is that every module down samples the input to the DAW's sample rate by default and up samples it after processing e.g.

Code: Select all

-48kHz-in->[48kHz*2-MXXX->[96kHz/2-Limiter-48kHz*2]->96/2kHz-out]->

That's obviously a possibility, but it doesn't make too much sense to me. If you only want to over sample specific modules and leave the rest alone, you can simply leave MXXX's oversampling at 1x (disabled)

I hope that makes sense.

[Faiky]

I think our Held is right. Yes that makes sense, thank you!
PS: With MSF, however, I also thought that the LFO's would be upsampled as well, unfortunately this is not the case.

[steve2KVR]

Indeed, makes total sense, and seems consistent with the reactions when "punching the buttons." However, and I'm not intending to be augmentative, but the actual situation remains ambiguous to me.../s~

[Held]

[...] but the actual situation remains ambiguous to me.../s~

I'm not sure what you mean. Could you elaborate?

[Faiky]

If you would ask me, my situation is quarantine and it makes a little
