Hi guys,

One of the main reasons why I upgraded to Cubase SX 3.1 is to make use of the Audio Warp feature on Vocals. I want to use it to tighten up vocal performances but all I am getting is a varying grainy sound throughout the vocal passages. Just when I've moved the warp tabs around to get a clean and smooth edit, I go and place other warp tabs on audio occuring later in the same clip and it destroys the previous part which i spent ages making smooth!! Do I need to be splitting up vocal phrases into seperate bounces in order to make this audio warp feature usable? It seems that whenever I bounce each vocal sentence to a seperate clip I can make the part perfect with audio warp without affecting other clips because they're obviously seperated. Shouldn't I be able to warp one entire 3 minute vocal clip to perfection without new warp tabs affecting audio which occured 1 minute ago? This is strange strange behaviour and I am not meeting record company deadlines for final mixes. I have had to go back to my old method of chopping/moving/crossfading vocal phrases to tighten up passages when I could've stayed with SX 2.2 and done the same thing.

I am regretting this upgrade sincerely. Not to mention after I have finally warped the audio to what seems to be a "reasonable" sound quality, I cannot add autotune to the warped parts because that grainy sound comes back even worse. I need to bounce the whole warp section which I am never really satisfied with in order to apply autotune without unexpected sound quality degradation. What is the point in recording in 24 bit if everything ends up sounding 8 bit in the end?

What is a successful way to warp and autotune vocals quickly and reasonable sounding? Autotune first > warp or some other combination? Are other people here needing to bounce small sections of audio to make the warp feature stable?

Cheers,
Anthony



I just composed a reply to this thread, but is was locked while I was typing.........

Anyway.

I have a project here right now that has vocals recorded in 24bit via an AKG414 mic and Apogee Trak 2 Mic Pre/ AD Convertor. It sounds very clean as you would expect. THe vocal has also been autotuned and still sounds clean.

The project was recorded at fixed tempo, and has since had the tempo changed in various places by applying Musical Mode to all audio events. This means the vocal has been subjected to the real time stimestretch algorithm ( not MPEX2 ).

Now while the result is not as perfect as the original ( which I wouldn't expect ), the vocal is still pretty clean and usable.

I appreciate this is a different use than using the warp tabs to twaking the timing of vocal performances, but the algorithm is still the same isn't it.

Or are you guys saying it's the MPEX2 algorithm that's broken, and not the supposedly inderiour quality real-time algorithm.

Btw I tighten up vocal perofrmances by the traditional method of snipping, sliding and X-fading. But I like to use real tiem time stretch with musical mode for creative use of tempo changes to inject some human feel to the song's tempo.

Christian is right. It's hard to understand EXACTLY what the problem is. Can someone ( DNA perhaps? ) explain in more detail where it is going wrong.

Yes. A specific list of the problems would be great.

I also remember reading on the Nuendo forum a while ago (and this isn't going to be too helpful, but maybe it'll jog someone else's memory too) about how the 'quality,' settings are poorly labeled...

Most of us tend to always press, 'highest quality,' when given the choice, but on the Nuendo forum it was discovered that the different quality levels affect the results in odd ways... that highest quality might not be best for vocals but rather for drums... or something like that... anyone else catch that post?

Something to think about at any rate.

But to echo Paul's request, reprint from the other thread what's broken and why and the exact steps to reproduce the problem... statements like, 'it sucks and is unprofessional,' don't help at all without the corresponding example... and the precise steps and even if you have the server space, an example file or two...

I have fiddled around with SX3's audio warp feature since SX3 came out. In fact, audio warp was one of the reasons I upgraded from
SX2.

What I found out was, that audio warp contained ugly bugs and ugly soundings, and it still does in SX3.1.1. Another thing with the current
Audio Warp implementation is, that it is difficult and slow to use, if you wants fair results.

I never thought, that audio warp had anything to do with MPEX, as audio warp has its own engine, right?! I don't really know whats happend
when you freeze warped audio, other that its introduce new problems and bugs with the freezed audio.

To name a few problems and bugs with the SX3 audio warp:

1.
The well known "rumble" sound, which appears here and there and everywhere. You can make some settings, which makes much of the rumble
sound go away - just to find out, that the warping act differently in another place. You can make settings (without too much rumble sound), that
works alright for a specific task, but will probably don't work alright for tempo changes, as they will start to sound bad.

For me, its very difficult to make a really really good settings, that works without the "rumble sound", and sound good for mixed material, and that
allow some tempo changes and still sound good. I have tried many times, but it won't work. I always end up by allowing the "rumble" sound, and
then get good tempo changes sound.

2.
Edit problems with Audio Warp on, is a confirmed bug. Audio warped events sometimes plays more of the events, that is actually now visible. Normally,
its buggin' me, when I have made some cut edits on the ending of an event, and then still hear's something from a bassdrum, that is not visible on the
event?! Christian has confirmed this bug a long time ago.

Also the strange waveform drawings on the events, when you drag on the small fadeout/fadein gadgets. It doesn't show whats actually is played back?

3.
I have also warped freezed a complete warped mix I have made (5 stereo audio tracks, 12 mins lenght), which resulted in sound caos and strange .
Most notible, was the strange volume droppings in the middle of an event? Suddenly the waveform data and volume was faded completely down, and
fast up again on random places in my audio. And there was strange clicks in my audio, which wasn't there before the freezing?!
Undo everything worked Smile now I only use realtime warping.

One positive thing about freezing everything was, that the "rumble" sound went nearly away. I still was there, but not in the same degree as before freezing.

4.
About the sample editor functions, I think the warp audio and tempo functions are usable, but definatly not fast. And a little thing that has irritated me, is the
small handles when you use the rangetool to find a good loop for the tempo tool. Its easy to click a little wrong with the little rangetool arrow and thereby loose
the complete range, that already was there, if you just needed to make small adjustments. Then you need to start all over again.

And then the audition buttons, the playtool. It really irritate me, that when you have set up a range or a loop, that everytime yo press the audio play button,
it start playback from the beginning of the loop or range. You can't audition from where your songlocator is, unless you press play and navigate there manually!

5.
As for the function in the sample editor, I miss an advanced autocalculation tool like in Live5. It should auto-calculate BPM's on imported audio, from some advanced settings.

I'm also missing a better warped editor grid, where it should be faster and more easy to warp long files like a complete song. The current implementation is fine for small loops, but its easy to loose overview of whats going on.

6.
I'm also having some problems with the tightness of my warped audio. Its very hard, if not impossible to align more warped track up playing together. For me,
it always end up sound like a bad live playback where it lack timing. Its like the graine engine corrects itself all the time, and sometimes needs to speed tempo
a little down or up, which you can hear. And when you freeze you warped audio, the timing change, which I thing is very strange?!

Like the freeze funtion change the timing somehow? Yeah, plus it add strange things to the audio?!


Regards,
SLL

The BIGGEST FLAW with the Audio Warp/Musical Mode IMO Is that is doesn't work at all if your project is ALREADY at a variable tempo before you start recording audio.


For example...

1] Record a freetempo midi instrument. Turn on Tempo Track and Use Timewarp to sync the bars andbeats to the performance.

2] Overdub some audio tracks.

3] Eveything OK so far,..................


4] Then try and use the Audiowarp to apply a local tempo map to the audio so you can tweak the tempo further.

5] It wont happen. As soon as you use warp tabs, and turn musical mode on. The Warp tabs you have carefully placed over the existing tempo track bar/beat positions move out of sync. It's like the Audiowarp only works with the underlying fixedtempo value.

This means the only way to retain editing oftempo in a project is to turn the tempo track OFF before recording new audio and applying warp tabs to it. Of course if you've ALREADY recorded variable tempo audio overdubs ( as in my above example ) you cannot do this and you're stuffed.


I do hope that SX4 fixes this important anomoly Smile

Why did Mr. Christian Dettner lock the other thread?

Is he trying to avoid the publicity of these negative truths about his company Steinberg and their flagship product?

How many complaints from different customers will it take for Steinberg to acknowledge the problem rather than deny it exists?

The same thing happened with the MIDI timing defect starting last Spring.

I don't think audiowarp has been developed, or was intended, to be used creatively. The intention is probably to apply corrections to existing material where those corrections don't introduce artifacts. If you strain that design too much you will induce artifacts especially if you use it on material that has already been warped. Even the specialist top end warping programs/machines introduce distortion at the extremes albeit that those distortions have been used creatively. They do cost considerably more, though.

As far as I know most other warping programs will fail at this too. The calculations involved seem pretty difficult. How would cubase know what has been left out of/added to the original material from the original signals by the previous warping process? It would need that info embedded somewhere in the file as a reference. I don't think so.

I have also had to use audio warp to correct variable tempo material where small changes were ok larger ones hit artifacts and when I finally got one of the latter to sound ok-ish then the life and soul had been sucked out of the performance. Sometimes tempo variations should be left. Most times, I think, but I digress. I am a drummer after all.

You could think I've missed the point you make about "before recording audio" but that again, I feel, is beyond the intended scope of audiowarp as the variables get bigger as layers are added. Even in a real (tape) studio situation I have been outvoted on whether to rerecord a drumtrack where I thought the tempo had moved too far (you wouldn't notice from the basic drumtrack generally) and I had to watch as layer after layer got rockier until after about 12 tracks the recording fell apart. You can fix it more with computers but not too much. Digital tapestretch comes to mind. That old recording adage comes to mind: "If you can trust any gizmo that cost less than $5,000 then you're very lucky."

Hello...

I have locked because it was filled with nonsense. I can´t read four pages of senseless remarks. This one here is the right way to express opinion, issues or desired improvements. This is constructive, the other was not.

texx is right btw... The main goal is to have a way to match audio with tempo. Audiowarp does that pretty well if it is used that way. For sure there are a lot of things which can be improved but over all it works as designed - I don´t think one can deny that. For sensible audio material you can still use offline stretching instead.

Dear Mr. Dettner,

Whether the form made sense to you is irrelevant to its right to exist and be exposed to other users and potential customers. It obviously made sense to many real users that they have been idenintifying with it and participating in it.

You are rationalizing your real motive, that is censorship of product defects to protect Steinberg.

What would really be constructive is that you investigate the problem by asking the users who are encountering the audio glitches to send you isolated project + audio files and promising them fixes.

You are simplying ignoring the issue, calling it nonsense and insisting that the product "works as designed", when it clearly does not, as proven by many many users.

A sucessful company like any other entity must exhibit maturity and responsibility.

How can you possibly know that? Have you got the original design documents or what?

Let us the see the "design documents" for SX4 that has addressed AudioWarp defects, then we will know we are not being ignored. According to Steinberg right now, it "Works as Designed" which implies that it does not need to be fixed.

Why are you taking your time to defend Steinberg anyway? Are you not a customer? What if one day you use AudioWarp in front of a client and it starts to Pop and Crackle?

First Christian, thanks for listning Wink

And Texx, I'm thinking the same. I would really like Audio Warp to from:

- SX3 Audio Warp light v1.0 - to - SX3 Audio Warp pro v4.0 together with SX4 Smile

Thats how I feel about it Rolling Eyes

just get ableton live, the warp works auto on all tracks and u can just assign a midi controller to speed slow down audio.

Cubase Warp is far too long winded.

You'll never get your problems solved on here just excused so just buy another product that works instead, maybe then steinberg will listen.

Buying another product like Live5 would be stupid, unless you only want to use its Audio Warp
feature professional. All other things in live5 feels a little thin compared to SX3.

No doubt that Live is good for "live" work, but SX3's workflow, GUI and the hole VST, VSTi implementation
is far away from Live5 in a positive direction. Where steiny has invented and build core functionality, it's much
more stable and intuitive. Thats also why I stay with Steiny, as they still is in the lead with - VST, VSTi, Delay comp.
GUI design, stabillity. Audio warp is something Steiny needed to implement, but not at newcomers. Sony Acid, Live was
there before.

Oh, Yea! Tape based studios neverwent wrong did they? Why shouldn't I defend Steinberg? Because you say so? ( snooty twat! )I'll certainly pitch in if they need a kick.

I tell the clients what it can and can't do. They can take it elsewhere if they like to. To an Ableton studio as well.

Audiowarp was not meant to correct bad tracks but to correct simple inconsistencys. Too many people expect Cubase products extras to work miracles (rare midi timing bugs aside). The rules are "Garbage in, garbage out." I'm afraid from what I see most of the noisiest protests come from posters not understanding the nature of Cubase and /or music. Use the robot as a recording tool which it was designed for. Anything else that works is a bonus. It is cheap. Don't expect the robot to write or improve your songs or recording material.
I see enough of this on the live circuit with too many mediocre musicians arguing and abusing sound engineers who fail to get a good sound when the band won't soundcheck properly and won't listen to good advice and get drunk and blame any body else for their bad gig rather than have a think first. They also show a thorough misunderstanding of sound, acoustics and volume. Some of them even tell the sound engineer they are sound engineers with "clients". I'm not a sound engineer but I do work with them a lot. All of these turks sound the same. They sound like some of you guys.

Happy new years to sound engineers.

Hey Paul,

I think SLL nailed it but I will just confirm:


* Mpex2 is broken and doesn't work at all. It makes things sound like a really bad mp3 encode.
* The realtime warp algorithm is volatile and causes many degradations in the sound quality of the audio events - even on tiny corrections.
* What's worse is if you try to correct and get a "consistent" sound from it, it will change later if you add more warp tabs further along an event
* Audio warp sometimes sounds better on 50% stretched material than on 20% stretched material and this is total rubbish. This proves it could be improved immensely. It should sound decent on small edits and become increasingly degraded the more things get stretched just like any other time stretcher. That being said, knock the warp tab out of the way by a tiny amount and your 50% stretch that sounded great now sounds like it has clicks and pops etc etc. Move the audio warp around to find the sweet spot again and it takes forever.
* The worse thing of all is trying to add processing whether it be tuning or eq to an event that has been warped and the clicks and pops find new places to manifest.


I've stopped wasting my time trying to get a perfectly edited piece of audio using warp because it changes all the time. I have to create little vocal bounces of each phrase in order to use it without changing as the project takes shape. It's a hassle but it's working for now.


Cheers,
Anthony

Ignore this if you have done this already. When you stretch you use the tracks in musical mode. Do you also go into the pool and put your audio segments in musical mode and match the tempo of them up to the present or original starting tempo? (yes, all 500! of them, I know)

If you haven't done this before and you try it. What happens? Any improvement?

Cheers for that Smile

Interesting stuff. I haven't actually used to Warp tabs for sometime. However I do use musical mode for varying tempo.. i.e I record a project at a fixed tempo, and then apply musical mode ( and original tempo ) to the audio events so I can add tempo variablity to the project for 'feel' reasons.

This works OK. The audio is real time stretched without clicks or pops. The sound degradation exists, but is nothing more than you would expect from a timestretch algo, and without a reference to the original audio no one would notice the timestretching. Of course MPEX2 is not being used in this scenario, and neither are warp tabs.

Like I said I've always snipped, x-faded and bounced for editing performances. To be honest I never even tried using warp tabs for this purpose as I can use the manual method pretty quickly anyway

Audiowarp was designed to match tempos. Whether this is for creative use or for 'fixing' is entirely up to the user. You can't dictate to people what Audiowarp should or should not be used for. Besides everyone knows that timestretching distorts the original signal and no one expects this to do it perfectly.

You are missng the point. by a mile.

Scenario 1]

You have a fixed tempo project. You set the tempo and apply musical mode to the audio events. You then turn on the tempo track and create tempo events to varythe projects tempo. e.g to speed up the chorus' or pregresively slow down teh ending, etc,etc

This works fine. It's a creative process and I do it all the time.

Scenario 2]

You have a fixed tempo project. you have a an audio file containing a performance that is of variable tempo. You use warp tabs on the audio file to match it's tempo to the fixed tempo project. The last time I tried this it worked fine

Scenario 3]

You have a project that has a varying tempo defined by the tempo track. You then overdub audio on this project. Assuming the playing is tight, the tempo of this audio varies with the propject's tempo track. All good so far. Using the Tempo Track you now wish to edit the tempo of the project further. e.g you decide the chorus wasn't fast enough. But of course doing this will throw your overdub out of sync. So this is where you need to use Warp Tabs to give this audio a local tempo map so it can follow further tempo tweaks in the project.

The obvious way is to create warp tabs on every down beat of the bar ( or every beat for mroe accuracy ) and turn on musicla mode. This is easy to do, but as soon as you turn on musical mode the audio is thrown out of sync before you even start to tweak the main project tempo. ( My speculation for this not working is that msuicl mode tried to force the warp tabs to the underlying fixed tempo of the project, and not the tempo track.

Thus: Scenario 3] doe NOT work. And IMHO it's a serious limitation of Audio Warp.

In the past Tempo flexibility has always a limitation of using audio in DAWs. Audiowarp goes a long way to achieving this flexibility ( issues over sound quality excepted ) but it needs some further improvements. I've spoken directly to the developer of Audiowarp and told him of these tempo track/audiowarp issues. I really hope SX4 brings the improvements.

Look Mr. texx,

I did not ask you to do anything, only asked why you are peculiarly defending Steinberg.

You have no right to attack me, and call me a "snooty twat", or attack my musicianship. If anything Steinberg should moderate this type of behavoir on this forum. You have agreed to the rules of conduct for this forum.

I am rightfully voicing our complaint about the product having defects and not meeting upto advertised specifications. We are not complaining about the quality of AudioWarp sound, we are stating that it delivers Corrupted Audio often in areas of the audio clip where it is not even applying a stretch at all.

It is non of your business how I use this feature, and whether I use it to correct bad or perfect amazing performances. You do not know me, and would not know me acting like this.

However, you must remain civilized.

Please name the issues you have.

Hey Paul,




* Mpex2 is broken and doesn't work at all. It makes things sound like a really bad mp3 encode.
* The realtime warp algorithm is volatile and causes many degradations in the sound quality of the audio events - even on tiny correction.


I've stopped wasting my time trying to get a perfectly edited piece of audio using warp because it changes all the time. I have to create little vocal bounces of each phrase in order to use it without changing as the project takes shape. It's a hassle but it's working for now.


Cheers,
Anthony


I thougth i didn´t post anymore on this matter,for once because CD closed the other thread just after i posted some opinion, second because i don´t use Audio Warp much, not even for creative purposes, for that a regular sampler fits the bill a lot closer to me.

Now saying Mpex is broken it triggers on me the unpleasant mean Steinberg zealot but i´ll try to tone down cause in fact both are two functions that go way over my head, albeit i use Mpex even to tigthen up entire tunes, just stretching a tune 5 or 10 seconds makes it feel a lot better.

I have used Ableton and Acid, both are great and fun but not a musical tool that can be compared with SX, regarding streching algos: both, Acid and Live, used at extreme settings introduce a lot more artifacts than SX´s Mpex.

Did you chek on preferences how many Mpex modes there are???

Here is one of the issues I have come across;

An audio clip, I put in 3 audiowarp tabs, let's call them Left, Middle and Right. I moved the Middle one to improve the timing of a note, the Left and the Right ones were untouched. This means that what came after the Right tab was completely unstretched, yet the sound after the Right tab becomes corrupted depending on the position of the Middle tab, slightly moving it fixes it sometimes.. sometimes not.

This has happened several times before. I tried freezing to MPEX, which often produced more gaps and clicks. The best solution was to bounce the subsection of the audio to another clip before warping it.

I do not have any projects with that defect sitting in them, but the next time this happens I can just keep that audio clip with the audiwarp settings causing the problem and send you a simplified project file, if you promise to look at it and invetigate it.

If everybody with a problem does the same, and you guys investigate and fix it, then we can take care ot this.

Hi
I also upgraded to 3 thinking audio warp could do what it seemed to be saying. It doesnt really. If you want something to really do vocals wells then buy melodyne; without peer. I have and its fantastic and not hard to use. If you really want to fix drums then buy beatquantiser; better than beat detective and cheaper. Overall SX is a good product and it would be nice if marketing of the features was a little less bloated. It cant handle multitrack audio quantising etc either so dont even go there. Just face the hard facts that there are no progs out there that do everything well. Just use SX for what it does do well. Just my resolution (worked for me). Software is constantly evolving and you get there by everyone putting in good info

Is it possible to provide a small example project zipped together to sent it over to me?

Dear Mr. Dettner,

Certainly I can do that. The next time this happens I will minimize the project around the problem audiowarp clip, zip it and send it to you. Perhaps if I get the free time, I will try to reproduce it sooner.

Thank you for your interest!

there IS some real cnuts here, that make it real difficult to get to the bottom of this.

first off, i think the prob of the orig poster (anthony) is that he should consider shelling out a little and buy melodyne. using two artefact-prone processes in series is certain to destroy your sound, if you are unlucky (which you seem to be) the second process will optimize the artefact-sound instead of the signal.

secondly, there are a lot of bugs with this, and as beyond said in the beginning, this feature just can't have been tested appropriately. but with each update there are problems that are adressed (and also sometimes new ones are introduced). so there is progress. afaik all of the bugs have been fixed in nuendo 3.2, but i may be mistaken.

thirdly, there have been many things mixed up with these feature. there are bugs, there is misusage and there are bad-workflow-items here. it would benefit us all to sort those three out, else this thread will only be a whingy-whiny time-consumer.

as for mpex. it sucks. try (timebandit) standard (complex) algo.

cheers and more of a real happy new year.

Of course you are allowed your opinion and I am not allowed mine. Typical reaction of a sn... Sorry! Sir. You're exactly like those boys I keep seeing who want to use the pa as an extension of their cheap amp "because they paid for it". The whole piece was not about you, only the first paragraph, how could it be? You're perfect. I'll do whatever you say.
NAAAaaaHHHHhh!
It is everybodys business how the feature is used by different persons as we can then define what it can be used for or not and it can be described so. If you can use it for creative purposes do so if it works. But it is not going to, and nothing ever will, work creatively for all occasions. One mans Marshall amp is another mans Peavey. You swap them around they hate it but they can't rant about the crapularity of each others' amps forever, they swap and get on with it.

For what you want to use it for. It doesn't work! So get something that does. Ableton may fit that bill. Studios used to have million pound running costs per year to keep up on those terms, same as us.

Sure something in the whole timing department needs fixing but not for all systems and that will take some time to sort out.

Yes, when you tick the boxes for musical mode in the Pool you get asked (if your samples are of varying tempos) if you want to change the tempo to the rate of the project. Which I presume is the starting tempo (or the fixed) for the project if you've already got more than one. If you have got more than one then the calculations that spring to mind are not nice. Much like the calculations you may have to do to live or prerecorded and mixed material when someone asks you to "clean it up". It's like trying to change my wifes mind... but then she is v 1.00 and I wouldn't want the program changed drastically. Though after a lot of complaining to WTF@PaMainlaw.com I had to accept that the nappychange module had a serious defect so I have to do it freehand.
