TIME STRETCH

How is the new timestretch you lucky people, im still waiting for my upgrade.

In Digital Performer, timestretching is constructive (creates a new audio file), and when you timestretch something multiple times, it always references the ORIGINAL file. That way you avoid adding artifacts on top of artifacts every time.
Does Logic do this yet, and if not, how do you do a similar thing "by hand?"
In logic, sadly this is not yet automated. What you "should" do, is double click on the region you're going to timestrech (which will bring up the sample editor) and then back-up the audio file before performing the stretch.
The actual command is Audiofile -> Backup, but Command-B is the keyboard shortcut so you can just hit that keystroke before you time-stretch - and then you can revert without worry.
Remember that you can also set the number of time stretch undos in logic's preferences.

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!

Oh really, it is supposed to be fixed in v 9.1.7
Then I'll have to give it a try.
Hi
Seems to work OK here

Did I understand correctly that just by ""renaming"" Logic 9.1.6 inside the application folder it will keep it functioning in case I wanna revert to it later??
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

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*.

I know the marquee tool, but I don't see how it can be used to time stretch ?
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.

Time stretch has stopped working in Premiere Elements 13.

I've downloaded the latest Adobe updates. I am using a Windows 8 64 bit computer. I have previously (in the last few weeks) used time stretch to speed up and slow down without any problems but now I can't get it to work in any of my projects. All video files shot with an iPod Touch or iPhone. Has anyone else had this problem? Any ideas on how to fix it?

Chris
As a point of reference for your Premiere Elements 13 question, I have a iPod Touch 4th generation (H.264.mov 1280 x 720 @ 24 progressive frames per second), and I have no problems using Time Stretch or Time Remapping in a 13/13.1 project or other versions.
I would invoke the interference of a possible variable frame rate rather than a constant one involved with your particular type of video (from iPod or iPhone) and Time Stretch, but I am not having any problem with my iPod Touch video (with minimal variable frame rate) and Time Stretch in Premiere Elements. If you want to explore that idea further, you could convert your video's variable frame into a constant one using the free HandBrake program. Then import HandBrake's H.264.mp4 export into your Premiere Elements 13/13.1 project and determine if you can then apply Time Stretch to that clip.
Have you applied the Shake Stabilizer to your clip before trying to apply the Time Stretch? For that matter, what effects, if any, have you applied to your video clip before trying to apply Time Stretch to it?
All of the above is based on Time Stretch no working for you in a new project with new source media.

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...

Gradual Time Stretch - Is it Possible???

I'm using logic to mix together a heap of songs. Naturally they all have different tempos.
I'm using the quick and dirty time stretch method (option+drag) on the audio clips. I'm wondering, is it possible to automate some how a gradual time stretch, so the clip starts slower then speeds up?
I guess I'm trying to emulate the changing speed capabilities of a pair of turntables in Logic.

This may not be totally what you're looking for, but check out a little free AU called Turntablist. You can find it here: http://destroyfx.smartelectronix.com/audiounits.html
You load it up in an instrument track, then load an aiff straight into the AU, and you can speed up, slow down, scratch, etc, and it sounds really nice.
If you really want an app with a lot of flexibility to manipulate files and tempo, pitch, etc on the fly, check out Live. It's much more suited to that stuff.
Good Luck!

Burn Audio CD and Time Stretching audio - software on the iMac?

I have a new iMac 24 running OSX 10.4.9 and had two questions:
1) Is there software on the iMac for buring an Audio CD? Created a song and I am trying to figure this one out.
2) Is Garageband able to time-stretch a song? I need to edit some performance songs that need to end at a specific time. I use Sonar on my PC to do this but wondered if Garageband or another utility on my iMac could handle this.
Thanks!

1) iTunes will do that (not GB). Just create a playlist and click "Burn Audio CD". (That's the default setting.)
2) GarageBand can do that, but you'll have to play around a lot to achieve it. I'd recommend an audio editor like Audacity or SoundStudio - there you can change the tempo of a song (without affecting the pitch), and it will tell you immediately how long the result will be.

Time stretching a piece of audio in LE7

I've been using Cubase for years and since I have been doing alot of remix work lately alot of the songs are being sent have been in Logic so I got a copy of Logic Express and I'm able to navigate my way around the basics with no problem. In Cubase SX3 -or CB4 you can time stretch a sample from lets say 124 to 126 bpm. The only thing I see in Logic is the time machine? Is this the way to do what I need to do? I know, I know, read the manual but since I have to work quickly I thought I'd ask here. Any help?

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.

Now all clips/files in multitrack screen automatically begin time stretching if boundaries are adjusted - WHY?

I am in the middle fo a large multitrack session with about 40 different tracks and now if I try to adjust the boundaries of a clip - any clip, it begins to time stretch automatically - even when the clip si not set up as being looped!. Is there a setting that causes this? Can it be fixed or is it just another AA3.0 bug? Help! - This session has now become extremely diificult especially if I adjust a clip boundary and that clip starts some knid of mysterious self-generated time stretching.
Any help is greatly appreciarted

I'm not at the studio at the moment but if I recall you would need to uncheck 'Enable Clip Time Stretching" under the 'View' menu option.
I'm pretty sure locking the clips in time will do the same thing.
Can confirm that this is indeed correct...

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?

HT5146 logic 9.1.8 time stretching problem

Time stretch in logic 9.1.8 is not working in arrange window or sample editor.
The arrange window stretching causes the computer to process...but nothing changes in the audio track. Time stretching in the editor is grayed out along with other options in that window. I have tried to stretch mp3, wav, aiff from my samples collection and also my own recorded aiffs..also tried using different file locations on my drives..also have checked permissions and have restarted my computer a few times...nothing works.
I am using an imac from end of 2011 on mountain lion.
anyknows how to get this to work?
thanks

I think it's one and/or the other.. I know compressed files cause problems but I also think it might be a permissions issue of some kind too...
Converting to CAF in the BIN, seems to get around both possibilities... and so far, every time i have converted the resulting file works perfectly fine..
The bit of the Logic Guide that seems to be the clue is this bit...
Note: It is not possible to assign fades to compressed audio files, nor can you destructively edit them.
Found here....
http://documentation.apple.com/en/logicpro/usermanual/index.html#chapter=11%26se ction=4
and stretching seems to be distructive.... (not Flex but drag stretch...)
Whats odd is it seems to do it graphically but then as soon as you click on the region, it goes back to it's original size!

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.

Shaking after time stretch

I've just tried out the new Premier Elements 11. Love the new format and once I found my way around, I really like the flow much better than 10.
I made sure I had my project for 11 set up like 10, and the settings on my Sony HCR-CX260V are exactly the same. When I apply the time stretch (above 100%) and render, the edited result in 11 is severe shakiness. When I used the same footage and applied the exact same % of time stretch in 10, the result was as smooth as can be. I use time stretch in almost every video I create so I really hope there is a fix for this (or you can tell me what I'm doing wrong in 11 that has changed from 10) as the flow in 11 is better. Thanks so much
Shelby

Have you tried using Time Remapping instead?
Are you seeing the shakiness even after you render the file?
Can you post a sample of this shakiness and link to it so that we can see what you're talking about? "Shakiness" could mean anything from frame rate stutter to a need for stabilization to an exaggeration of hand-held camera movements. We can't say for sure without looking at it.
