Voxengo OVC-128 1.10 massively-oversampled clipper plugin released

[mystran]

It's no compromise but still has the lowest CPU usage, and sounds absolutely wonderful.
Roll-off soft clip to 50ish to get (oversampled) inflator style harmonics or keep it hard to have clean shaven peaks to feed the limiters. wonderful

I wonder why it sounds so smooth, it's probably due to the quality SRC.

When it comes to distortion, especially so for hard clipping, the quality (and to a certain extent characteristics) of the oversampling filters is quite literally everything.

In fact, one can make the case that the quality of SRC is even more important than the actual oversampling factor, because even though increasing the oversampling factor will give you more bandwidth before aliasing, it's ultimately the SRC filters that are responsible for taking advantage of this bandwidth and as soon as those filters become the limiting factor, increasing the oversampling factor further does basically nothing for you.

Now, I have not actually tried this particular plugin (not yet anyway), but I have enough respect for Aleksey as a developer that I kinda don't even need to hear it in order to trust that it's great and the quality of SRC is probably not the limiting factor.

15 years of SRC research and tinkering does give results, sometimes anyway. Of course, for hard-clipping SRC qualities are basically what creates the sound. For soft-clipping, not so much.

V1.10 :

You've forgot to enable "phase" plot. What's displayed is a magnitude plot.

Depends on how hard you drive that soft-clipper.

[Halonmusic]

Great!

[DJErmac]

OK, best clipper I've tried.

Yes, all "compression" processes reduce stereofield.

No, but all "clipping" processes are killing audio fidelity.

Aleksey, I hope it's okay if I contact you via this thread.

My question is about the "auto" setting for oversampling in some of your other non-linear plugins (saturations etc.). Im not sure the "auto" setting for oversampling is working correctly. I just did a test using Tube Amp in a 44.1 khz project in Ableton Live 11. Test signal is a sine at 8372hz (C9). On the left there is the frequency plot of the saturated signal without oversampling and set to "auto", so I expect the aliasing to largely disappear after the file has been exported. The rightern instance of SPAN show the file after export and reimport into Ableton. The exact same aliasing profile, no oversampling has been applied during export, contrary to expected behaviour.

I double checked by manually switching the oversampling to 8x on the original instance (in the general settings I have chosen 8x as the oversampling rate for auto). This is how it's supposed to look like after successful oversampling applied during export:

So it seems that the "auto" setting is not working in Ableton 11. Maybe others can verify using other DAWs.

It works in logic (sort of*). Try having the GUI open and then bouncing, if the plugin displays a green "OFFLINE RENDER" at the bottom right corner then it works.
If it doesn't, then the plugin doesn't receive the flag from the DAW.


*It doesn't work in logic because when Logic flags the plugin that it should render offline, Logic itself doesn't recalculate latency so anything (not just Voxengo) that changes latency for offline renders is effectively out of sync.

[Aleksey Vaneev]

The "offline render" state that engages the "Auto" oversampling is out of plug-in's control. I know it works fine in Reaper, but not in all hosts.

That's fair. I was under the impression that most common and current DAWs would support such a function, especially a highly popular one like Ableton. Does that mean that auto-oversampling at rendering settings, no matter which plugins, don't work in Ableton? I will look into that. I always relied on the Auto-Oversampling feature, only realizing now that it probably did not work all the time. I guess I should set a default preset with 4x OS engaged for Tube Amp.

By the way: the signal seems a bit altered after export: while the aliasing remains (OS not applied at Auto setting), there is an increase in noise-floor, that looks dither-like, AFTER export. Is there a built-in dither? I deactivated all dither settings in Ableton and no sample-rate conversion occured.

No, there's no built-in dither in Tube Amp.
