The 100 Dollar Matching Bias Tones in Helix challenge MKII

[Sascha Franck]

Maybe the IR loader in Bias Amp is doing something funny?

That's something I suspected in an earlier version of Bias FX already (not worrying much about it personally, though, as I'm completely done with that company for good reasons).

Sounds pretty damn spot on from my iPad speaker!

High Fidelity !

 

[Sascha Franck]

Fwiw, when I tried to match the tone, I was using the ANGL Meteor in HXN and got pretty close (at least I think so...). Could post some results but it'd likely be a decent idea to know which version would be the one to compare to...

I wonder if I did something wrong in my renders. I should do a version where I use helix's IR loader instead.

This sounds pretty damn close! Playing with it now. Interesting that it is the Vitriol amp, wasn't that added very recently?

Something is not right, "Bias Output-glued" in post #1 sounds very different than applying your LAR48k IR later in DAW on your clip from post #13, they should sound identical.

I noticed the same thing when loading the IR into mixIR2 -- notsomuch with the IR loaded into Native

Yes.

Maybe the IR itself is broken.
Doesn't matter in my case, I matched to the 'no cab' track.

Here's using the Helix IR loader instead, and all new copies just in case....All that said, the preset you made seems so damn close, it maybe doesnt matter, trying to see how to clear up enough DSP for the vitriol amp in my kitchen sink preset

If there's any way it could be done on the Angl Meteor, that would be awesome, its a lot less dsp than vitriol

 

[Warmart]

Can't you just use a Quad Cortex to profile your Bias?

I'm leaving now. . . . . . .

It actually works perfect for that, as does the Revalver profiler and the audio assault one. But I'd love to just have it on the helix

I think the weird area around where an LPF would be in the bias file has to do with Bias' weird (or possibly non existent) anti aliasing filter

 

[pipelineaudio]

Pretty blown away by how close James got those curves with so few eq moves!

 

[pipelineaudio]

Is that Voxengo SPAN?

 

[James Freeman]

Is that Voxengo SPAN?

Voxengo SPAN Plus.
Best analyzer I've used, it is an invaluable tool for me.

I was close with your original file already, will give the IR-free version a testrun later on. Here's the last used settings:

and I also slapped a Tilt EQ in front (instead of going for the good ole TS trick):

Oh, and a post 10-band EQ:

Followed by your IR loaded into HXN.

No audio yet, fooled around too much with some other stuff in the meantime, so something changed inmidst of that file mess in my audiofile folder (was already going for your second batch of files), but you might want to give these settings a try.

@James Freeman The Bias tubescreamer seems to add 3.3db when it is alone and with your pink noise running thru it.

In order top match that in your preset, I set the scream 808's level to 5.3 and then added 12 dB output level to the parametric EQ following it. I then used Youlean to see what the noise floor was, and ended up setting the pre gain of the vitriol amp down to 1.7dB, as opposed to the original 6.0dB in your preset

This seems to get it pretty close..Is there anything wrong with doing it that way?

Check yer pink noise

There are four rules I live by:

1. Never get less than 12 hours sleep
2. Never play cards with a man that has the same name as a city
3. Never get involved with a woman with a tattoo of a dagger on her body
4. Always run two pink noise files through your plugins

Everything else is cream cheese.

There is no 'wrong', tweak until you're satisfied with the results.
I matched the gain of the isolated tube screamer and isolated amp separately from your first upload, I am not responsible for any hidden weird stuff when they are both enabled, although I did see that the gain doesn't match with the -75db noise when both are enabled.

Anyway, I think you got the handle of this so just keep experimenting and tweaking.

Maybe this post will further help (gain matching only):

Calibrating Helix Native Input Level

Ok, so I decided to find out the correct input level for different plugins of the same amp (Soldano) by trying to match the amount of gain in the sound of each one. Assuming the Helix has the correct input level (I'm using HX Stomp as interface) I fixed the gain knob of each plugin at 5, with...
