VariAudio export issues

  1. Analyse 15 seconds of audio in VariAudio
  2. Raw values:
    E0 -20%
    G0 -3%
    A0 -9%
  3. Adjust to 90% tuned. Adjusted values :
    E0 -2%
    G0 -0%
    A0 -1%
  4. Analysed values after using either Flatten, Bounce or Export:
    E0 -5%
    G0 -1%
    A0 -+1%
    Is this the expected behaviour?

I’ve subjectively noticed flattening sometimes seems to change the VA results, but never quantified it like the OP did.

Anyone here know why the OP might have gotten these results?

I have tested this rigorously and I was surprised by the results. Strangely, no-one seems bothered. I keep having to pay mix engineers to re-tune vocals and I prefer the Cubase results - but they don’t export well enough for them.

So you’re re-analysising already processed audio and then relying on the analysis results, is that correct?

As the final processed audio is not going to be perfect i’d say there’s always a chance of the analysis being thrown out when re-analysed again. But must admit, never tried it.

Have you tried routing the output of the live variaudio track into a new audio track and recording it live? Then compare that to the flatten/render to see if it nulls? As that would be my first question as to whether the render is accurate or not.

Also, are you using sine tones to test this, or actual harmonic content such as vocals or some other solo instrument? I may have a play later to see what you mean.

I’m using real vocals. It’s driving me nuts. I only re-analysed it because I was listening to it soloed and thought ā€œthat’s odd - I fixed that noteā€ I look and it’s another value altogether. I wish Steinberg would respond with - a) this is how you best achieve a rendered vocal with VariAudio and b) here’s the margin for error. This is a real problem for me. I can’t send this song without working it out. Or the engineer will charge me for Melodyne and I don’t use blanket autotune. I spend hours on this stuff. I just want what I hear, to be rendered correctly. No-one I know who is any good, mixes in Cubase. This is not a criticism - it’s fact. Seriously, I’d bounce it through an analog channel but it adds noise. I’m wondering how this test would go in Nuendo? Is it the same algorithm?

My guess is that the value you see after adjusting, is the original analysis of the audio multiplied by some factor, rather than a re-analysis of the output audio.

Thus, it makes total sense that a new analysis would show a different value, because all this pitch correction software is a bunch of heuristics – meaning, it’s not a mathematically linear function, and re-running the analysis on processed audio will come up with a different result.

If 90% correction doesn’t do it for you, try 98%?

just be done with it and use melodyne plug…sorry thats my advice
or better still fight the perfect culture and reintroduce some human imperfection…just rehearse and spend the time getting it right on the instrument…when I track someone…more than 3 issues and its a retake. Comping has its on issues

I think I’ll take your advice.

Sorry - we are in different universes here. I’m not seeking perfection. I don’t make anything perfect. If I buy a camera and it doesn’t reproduce JPEGS like it does to a screen, I buy another camera. This is a fail from Steinberg, on a process they sell as a feature.

I didnt mean it negatively. I think fixing a couple of mistakes in a performance is no issue…but after doing pitch correcting for about 10 years straight on various stuff…you cant unnotice now hehe.

Has really cut down my reference track library though.

Time alignment is ok in Cubase…but for the amount I now use pitch correction; I already had melodyne and its not that expensive tbh

It would be nice if there was a succinct vid from Steiny though demoing an actual proof of concept in real world application…would stop a lot of neg as you def know it can be done

Luv to hear some of your work :slight_smile:

@pkmusic i have used variaudio for years and could never get the render/bounce/flatten version to sound the same.

Hmmm. This is what I was afraid of. OK. I have to move on. I’ll buy the basic Melodyne. Thanks.

I appreciate your time in posting, sorry if I came across (as cross) I’m just disappointed I have to do all that work again. These are backing vocals and there’s so many. All I do is fix the strays but Lord it’s time consuming.

Melodyne is top of the heap…really…its money well spent. No package can do everything well and if its something you spend a lot of time on then you wont be sorry. The upgrade does polyphonic as well which is great if its a studio that does live takes eg guitar and vocals at same time.
Really, speed is everything…if you are spending that much time…you get lost in the forest. Im speaking from experience as I use to spend so much time on edit for my own stuff. I ended up just binning it and doing the takes again but with a lot of rehearsal and it just improves your artistry on the real stuff; it really does.
These days I do mostly only live artists and song can be recorded and mixed in 1-2 days. …and its a real joy tbh
Hope it all goes well for you.

I feel vocal tuning is more of a production choice, than mixing. And that should be where Cubase is strong.

It’s odd that you correct a note and then it’s not correct in the render. I’ve not come across that before. I’m definitely going to try it out this week though, as it has me curious.

Personally, for vocals, I prefer the results that variaudio gives than I do melodyne.

Thank you.

Firstly, thanks for your help with this. The problem (as jwatte said) appears to be in the way the analysis functions. However, the processes for export/render/bounce seem confusing to me. But here’s the wrap up, using invert phase.

  1. Render. This appears to be successful. The two tracks, phase inverted, do cancel each other out.
  2. Export. The exported track plays, but very quietly.
  3. Bounce. It’s as loud as the original. So nothing is actually done except combining audio segments. This may well be intentional, depending on your interpretation of ā€˜bounce’

I love Cubase and they’ve made huge improvements to the export function. But this seems like something that could be further improved. And out of fairness to the software engineers, I should say that I was wrong. VariAudio, using the Render function does work; even if an analysis cannot give the same result.

FWIW, your headline can now seem misleading and may cause others to avoid using it.

I use VariAudio and have Melodyne Assistant as well. I much prefer VariAudio because it it easier to use and seems to be top of the line without paying a top of the line price for it. (Melodyne costs as much as Cubase or more at full price.)

Moreover, I did some reading in various forums and found people commenting about how the polyphonic pitch correction is unreliable and can leave artifacts. So there’s a hype storm around the selling of that feature, too; one that seems not to prove itself in real world usage.

Reason has a good pitch correction feature, surprisingly. But VariAudio is what I now use for everything.

Im a long time user of melo…but Iim over relearning stuff too so it might be biased infor…you can get sales pretty cheap though. I have used the polyphonic and its like anything…it will vary with context but for basic stuff like vocal + guitar with bleed issues…its pretty decent. The fact that there is no reference other than 440 in variaudio makes it useless to me…I havent worked in 440 for a long time and as mentioned…it is very rare for me to pitch correct, its not part of mixing, I just give them other contacts if thats what they want.
But Im glad you got a solution and all the best with it

If render is always required to commit VariAudio (and the result does not return a visual confirmation on the success of this method), it adds an extra step to the task of sending out stems. If a track is only 4 bars long, it needs rendering and then exporting, so as to be the correct length. Rendering should be included in the audio export function. It would certainly save some time.
