Time Stretch tool won't stretch?

I have a sound effect of an explosion (pulled off web) that I need to time to a visual. The explosion audio is over too quickly, so I need to stretch it. Trouble is, when I click on the time stretch tool, my audio won't stretch beyond it's starting value. I can use the tool to shorten it just fine, but why can't I stretch it longer?
Any help would be appreciated.

I'm sorry, Milo, but if you captured your HDV video over Firewire connection, set up your project for HDV and you're using a 44.1 khz WAV file, you should not have to stretch the audio or the video.
It's possible, I guess, that you're using such an old version of the program (and possibly an older computer) and that it's having trouble playing high-def video at the same speed as it plays your audio. That would mean that they're still in synch -- they're just not playing back in the program at the same speed.
The test for that would be to use Share/Computer/WMV to output your movie (or a portion of it) as is (without changing either the audio or video speed) and seeing if it still loses synch. It really shouldn't.

Time remapping vs time stretch tools

What is the difference? Both can do the same thing it seems, apart from the fact that time remap can ramp in and out. Does one of them make interpolated frames?

Later today I will revisit your thread with more detailed comments on your question.
But for now, your following comment caught my attention, that is

Premiere Elements Time Stretch Tool can also be used for "ramped slow motion". Have you seen the YouTube video tutorial on the subject?

But I would make the distinction in my comments to follow about the easy of use as well as the absolute can and cannot do aspects involved.

Looking for a time-stretching app

Can you guys recommend your favourite time-stretching app? I'd like to find an easier way of lining up transients to beats, for example.
Thanks,
Shaun

Logic Pro 8 is also the application to use for time-stretching though!
See page 525 *Time Stretching Regions* in the *Logic Pro 8 User Manual*.

However, from your original post, now I'm thinking you don't really mean simple time stretching, but you mean doing something more like quantizing audio. Actually, I do use the transient capabilities of the marquee tool to find note beginnings and then move them to a bar location, which actually is a form of audio quantization.
However, Logic also has an audio quantize feature.
Check page 517 of the *Logic Pro 8 User Manual*. I have used this with varying amounts of success.
If you own Ableton Live, it has a better method (IMHO) for quantizing audio by doing something they call "warp markers". With Live, you simply place a warp marker on each transient (note start) that you wish to move, and then move it to the desired bar location. Live then time stretches your audio to match. Because it requires you to select these places, it is more seamless and has less artifacts than the algorithmic method in Logic. Still, if I only need to move a few note beginnings, I prefer to just stay in Logic and do it with the marquee tool.

Looking for an application that has great time stretch capabilities

Hello all,
I have Logic Pro 8 and I am still learning its capabilities. I do alot of sound design stuff and am looking for a spectacular time stretching application. I've fiddled with Logic's time stretch algorithms but so far I'm not thrilled with the results. I'm interested in really stetching things out to create new sounds. Here is a great example from Nine Inch Nails. It's a remix of Eraser off of Further Down The Spiral.
This particular remix version is called "Erased, Over, & Out." Here is an amazon link to have a listen.
http://www.amazon.com/gp/product/B000VZOBGI/ref=dmmu_dptrk11?ie=UTF8&qid=1212078077&sr=1-1
The vocals are EXTREMELY stretched out and take the form of a pad almost.
He is actually saying, "Erase me." Keep in mind the original vocal is only about 3 seconds long. I'd like to provide that example but the Amazon sample isn't long enough to get to that part. Maybe download it to listen. It's called Eraser, it's from "The Downward Spiral" album. (1994)
Now, does anyone know if Logic is capable of getting this good a result like the sample I provided? I've seen PT Elastic Time stretching capabilities and it sounds awesome, at least what I've heard from their demo video on elastic time. Can the same results be achieved in Logic Pro 8?
If not, what plugin do you recommend that could achieve this EXTREME time stretching stuff. Or, does anyone know what Nine Inch Nails used to get that effect on the vocals for that particular remix? I just think it's a limitless tool for sound design, but right now I'm feeling limited in the sound quality department. I know I can keep stretching and stretching and stretching the sample region but that sounds a digital mess when I get it to the point were I want it, so please, don't suggest I do that, unless you know a way to make it sound REALLY GOOD in Logic using the algorithms that come with the program. Step by step info would be lovely.
Thanx in advance...

Choppy or Digitized Audio w Time Stretch

Hi Guys,
I've got some audio I've been chopping and time stretching (voiceover to replace a video with poor audio). The VO was recorded in a 96kHz 24bit WAV file, and sounds great when I first played it. However, after I've been chopping (with the blade tool) and timestretching in STP, I'm finding that the audio now sounds digitized or choppy.
Does anyone know what's happening here and what I can do to fix it?
You can get a better idea of my process here. . .
Thanks,
Lawrence

Varispeed only works on the Masterbus, the final output of all tracks. Bouncing the output leaves you a 2-track master.
It's not an easy task because for one, your software tracks are MIDI based, their output is indeed audio but input is MIDI. To use Varispeed you would have to individually bounce each track/take, a mammoth job.
Perhaps someone can help you with Flex which may be you're best bet but is something I don't use very often.

How to use time stretch

Hello
Please...; I don't know how to use time stretch. When i select a music from a cd and import it in garage band. I change the tempo to accelarate but i can hear no change ... Would please help me and tell me if there is anyway. Thank you .... Olivier

Time Stretch in Premier Elements 10 prevents moving of clips in Timeline

Time Stretch in Premier Elements 10: after using it the Icon will not go away and I cannot now click-on and slide clips in the timeline. How can this be resolved?.

Before all else, I will ask, have you clicked on the Selection Tool which should be to the left of the Time Stretch Tool that you clicked on?

Where is the time stretching butten that makes it easy to time stretch with the cursor in premiere elements 13 ?

Why doesn't preimere elements have the option to trim the clip but the triming is in a matter of fact of - time stretch ? In premiere elements 10 there was a butten you could press and the curser became a trimer for time stretching. If there is an option like this in 13 I'll be happy to hear about. Thanks, Oren

Oren
What computer operating system is your Premiere Elements 13 running on? Background information for now.
In Premiere Elements 13 Expert workspace, you can access Time Stretch from the Tools Menu or use the keyboard shortcut Ctrl+R to bring up the Time Stretch dialog.
If you are interested in creating slow and fast motion effects, also see Time Remapping feature found under that Tool Menu.
As for the Premiere Elements 10 Timeline workspace, there is an icon (Time Stretch Tool with the keyboard shortcut X) I see no such icon in Premiere Elements 13.
Clicking on that icon in 10 will allow you to increase or decrease the duration of the Timeline video selected. And, if you go into the Premiere Elements 10 Edit Menu/Keyboard Customization, you will find a "Time Stretch Tool" command with the given keyboard shortcut X. At least, I do.
Even if I try to trigger a hidden "Time Stretch Tool" in 13 with the "Time Stretch Tool" shortcut X, I cannot. And, there is a Premiere Elements 13 Edit Menu/Keyboard Customization/ command Time Stretch Tool with keyboard shortcut X.
As for whys in Premiere Elements 13, you would need to take that up with Adobe who decides on the feature set for a given version. This is a user to user forum.
If you want to file an Adobe Feature Request Bug Report Form, you can use the following link
https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform&loc=en
I have found some interesting hidden commands/keyboard shortcuts with exploration and experimentation. So, I may do some more exploration on this to rule in or out
any possibility of a hidden Time Stretch Tool feature in 13.

Time stretch plug in?

I have and MBOX 1 and PT 7x and am may to move to an MBOX2 or a presonus firebox. The reason being is that I have FCP studio and the DAE of the MBOX will not allow me to run any other program using sound with Pro Tools open.
That said, how good is the time stretch plugin in Logic 8. I am a VO actor and sometimes I have to compress a file from 31-32 sec to 29 sec. PT does this without any artifacts as long as you don't go beyond 3 sec. It also does really well at keeping the entegrety of the .aif file. I have to find software and soundcard that can 1. rival PT and 2. give what I need to time stretch files.
Thanks.

Rather than Melodyne Studio, you could try the Melodyne plugin. It's a lot less expensive. The main difference is the lack of polyphonic algorrthms, but for single VO tracks it should be fine.
Melodyne gives you a lot more fluidity with both time and pitch and articulation on the fly. OTOH, the iZotope is nice because it integrates with the Time Machine.
There are pluses and minuses either way.

Time stretch percentage is greyed out

I'm trying to adjust the speed of a clip using the time stretch tool, but when I click on time stretch, the percentage is greyed out and I'm not able to modify it. I'm using Premiere Elements 10. Is this not a feature of Premiere Elements and is only available in Premiere Pro?

Time Stretch, by the way, can not be applied to titles any more than it can be applied to stills. Because, technically, they don't have "time". They're still graphics (even if you've applied animations to them).
Extending the clip should very much slow down the animation. But I guess it depends on which animation you've applied.
Is it roll/crawl animation? Or is it one of the Text Animations in the Title workspace? Or is it from somewhere else?
If it's one of the Text Animations, try going back into the Title workspace (after you've lengthened the clip's duration), select the text block and remove the animation -- then re-apply the animation.

WHERE IS TIME STRETCH, SHORTCUT BAR, GROUP CLIPS???

I can't do my job without 'em.... that's why I got a refund on CS5... PLEASE bring them, AND Hybrid Tool back like in Audition 3.0... I can't figure out why 4 of the most usefull tools from 3.0 were left out of CS5!!!
John

You could export the group of small videos as DV-AVI, then import this larger clip into your project and apply the time stretch to it.

Best Time-Stretch algorithm?

Although Logic's time-stretch algorithm's have come on a long way over the years, they're still no match for 3rd party equivalents.
I've been very impressed with Serato's Pitch n Time, & Melodyne, but wondered if I've over-looked any others? Any opinions on the most transparent time-stretch algorithm or software out there? (Primarily for monophonic sources - mainly vocals).

Aside from the ones you've mentioned I'm not sure there is much else thats comparable - except Pro Tools but thats a different kettle of fish.
I think aside from DNA in Melodyne, they improved the general monophonic algorithm in the new version and it's much better than it was.

High quality time stretch

After experimenting with time stretch in Audition 3.0 for a project, and comparing the best I could obtain from that with the best I could obtain with "Amazing Slow-Downer" (ASD), I found ASD to produce better time stretching. I still need to do some more experimenting, but this leads me to wonder if people have recommendations for stand-alone software or Audition plugins for good quality time stretching.

DEF need another app to get anything usable for time stretching.i would suggest melodyne for using it INSIDE of logic. outside of L8 you could use either melodyne or waves soundshifter (although the waves needs a host that will 'apply' plugins to the waveforms like cubase or pro tools.
these 2 yeild the best results, or you could get pro tools and give the X-Form plug a try, really nice results (the best IMO for strictly timestretching). melodyne will give the option of fixing timing inside the file as well.
just a couple of options.
oh, and theres izotope radius that will let you use it in place of L8s time machine, but would prob come in 3rd behind the other suggestions as far as quality.

Time stretch help please. These manuals are a PITA..

Hi all,
Well first a minor rant about the documentation with Logic Pro 7, for some reason no matter what task I need to perform I look into the reference guide and the plugin reference which are the two main books supplied with this application and all these books do is lightly discuss the the function of what you are researching.
As an example time stretching, I looked in the manual and then did a search for the online resource while in logic for the work time stretch, so it covers the details and explains that this function can be performed from the arrange window which is what I am trying to accomplish since I am working with a look and do not know its BPM, I would just like to strecth it down by bars/beats and make things fit.
I actually stumbled onto this once, but whern I try and review how to actually do this in the manual all I get it some very vague info that it can be done, unfortunately it just does not say how lol...
Am I missing something here? am I not looking in the right manual? I remeber way back before I moved to Nuendo I used to be in LAP 3 and the massive documentation actually told you how to perform the task your looking to do.
So I guess this is a two part question hehe.
1. How the heck do I perform this form the arrange window.
and
2. Am I just blkind and not looking at the right documentation here?
Thanks for your time and understanding, I just feel like a deer in headlights. Its like I know what the task is I am trying to accomplish and when I go to RTM I get just some info about that Logic can perform this function.
Maybe the manual expects you to have previous version knowledge.
Ahh anyways, thanks for hearing my rant and any assistance you can offer to me.
Cheers!

If they are looking for another Algo then how else can you explain that comment?
I'm sure if and when the OP has a problem with the sound of the algorithms in logic, he'll say so. for now, all the questioning has been about how to get a technique going where you can get your audio to the tempo you need it quickly and effectively in logic. we all know other apps like cubase and nuendo have more intuitive ways to do this right in the arrange window, but you can get a decent workflow going in logic as well. I don't have the time to get into it now but will try to post tomorrow.
I read that some suggest that its wise to buy a 3rd party pluggin like Izotopes?
3rd party add ons like izotope or serato aren't going to help you in terms of the way you use timestretching in logic... they don't add any functionality to the arrange window to make it easier to drag a region to stretch it like in cubase or anything like that. what they add is additional timestretching algorithms to logic that sound a whole lot better, but the way you actually access it in logic remains the same. I've not heard the izotope one, but I've used serato a lot in protools and it's one of the best I've heard, certainly better than the logic ones.
anyway as I said earlier I'll try and post tomorrow with some of my technique. I've done a lot of remixing in logic so I've had to do quite a bit of timestretching.
to be honest though, I really think sonther's post about the BPM counter plug in is the best way to get started. it sounds like you're used to just being able to grab the edge of a region and either stretch it longer or squeeze it shorter (in a different app obviously) and have the timestretch happen there and then.. and just do this until you got it sounding right. this way you don't ever really need to know the actual BPM of your original loop cos you can just drag it till it 'works'. sadly I don't think there's anything this simple in logic's arrange window to do it like this. but using the BPM counter, once you know the loop's BPM, you can just double click on it to open the sample editor window, open the time machine, type in the original tempo and the destination tempo in the corresponding fields, choose an algorithm that's appropriate and process it.
another idea you could try is the 'adjust region length to locators' function. say your audio is a 4 bar loop, and it perfectly loops at it's original tempo. so try putting it at the start of a bar, then drag a cycle region from the start of that bar to the end of 4 bars. the loop region should be either longer than the cycle or shorter (depending on if it's faster than your tempo or slower). select it, then use the function 'adjust region length to locators' (it's somewhere in the arrange window submenu, maybe under 'region', am not in front of logic now), making sure you selected an appropriate algorithm from the same menu. so now the loop will be timestretched or timesquished to fit to exactly that 4 bar length, meaning that it should now loop correctly, at the song tempo, over those 4 bars.
I have more technique I use if you're interested in hearing more, let me know as I haven't the time to go into it now. btw, if you use loops a lot and need to be able to control the groove and feel of audio files often for the music you make.. you should look at melodyne. there's an AU plug in version now that works very well in logic. I use it all the time.. most people know it as a pitch correction thing and just think of autotune when they think of it.. but it is an absolutely awesome tool for working with percussion and loops as well.
as a matter of fact, melodyne plug in could be just what you need. it gives you total control of the timing of audio, so you can regroove anything, shift stuff around, quantize the audio, and your loops will follow tempo once they've been melodyned. I used it recently on a project that had lots of badly played percussion loops that were sloppy and loose. fixed everything in no time, while keeping the groove. and in the bargain it sounds better than the timestretching algorithms in logic too.
go take a look.

Time stretch audio file to match tempo of track

Hi everyone, I am a new user of Logic express, and have found the info on this site extremely helpful, in conjunction with SFlogicninja's tutorials on youtube.
However, after watching a recent tutorial on Time stretching audio, i am now completely confused. Similar to the tutorial, i am trying to fit an audio region(an acapella track) to the tempo of the project. I have beat mapped the region to establish a tempo, but would like to experiment with slowing down or speeding up the track as a whole. As the acapella was created outside of Logic, i am bouncing the acapella track in order to be able to 'follow tempo'(as shown in the inspector). I have disabled the 'normalize' checkbox and bounced, but the bounced track still does not have the 'follow tempo' option in the inspector.
Any ideas as to why my bounced files cannot follow tempo. I can do it with audio that i create in Logic, but if i import any files, i was under the impression that by bouncing it within Logic, i could still obtain the same results?
I'm running out of hair to pull out!

Yep (but you will probably still need one called "Logic Pro" to get Software Update to see it)
I have mine setup to quickly switch from 32bit to 64 bit (2 copies with different names) and also previous versions.... works fine
