How do I change the speed of a track (not simply change tempo, but in a way that affects pitch)?

I'd like to be able to (essentially) duplicate the function of this Audacity feature:
Change Speed - Audacity Wiki
In Audacity, when I use "Change Speed," it modifies the recording in a fashion similar to playing a tape slower or faster than its normal speed (where pitch is shifted alongside the speed). Audition seems to have some tools that modify both pitch and time at once - the closest I've found to what I want to accomplish is the "Stretch and Pitch" tool, with Stretch and Pitch Shift locked - but the end result is markedly worse (or at least notably different) than what I get from Audacity.
The goal with this is to be able to put together a lesson on the interrelationship between frequency, pitch, and time, and the problem I have is that there doesn't seem to be a simple, one-step solution in Audition to modify an audio clip in this most basic of manners. I'm concerned that I may simply be missing where this feature might be, since it seems baffling that this operation wouldn't actually be there. Any help is appreciated - thanks!

Manipulating the sample rate was exactly it. Boy, I'm a dope. That's literally a frequency control.
Using the Stretch and Pitch effect simply gives a distorted sample - for example, if I had an audio recording of a VO that was sped up (Alvin-and-the-Chipmunks-style) and wanted to convert it back to its original pitch and duration, using that tool would get me the right length but not a very clear pitch. The sample rate's exactly what I want to control here, though, since that is basically a two-step version of what I was looking for. Thanks for the pointer.

  • How do you change the speed of a detached audio clip?

    I have a piece of detached audio.  Video Frame rate is 23.98.  The piece of Video above it is Video Frame Rate 24.
    How do I change the speed of this detached audio clip?

    Nope, the Automatic Speed did not work.  I exported the XML, and then ran it through X2Pro to try and get my AAF, and it still spits out conform warnings/errors on those same spots.  Automatic Speed apparently did nothing helpful to my situation.  (Can Anyone explain Automatic Speed?)
    Will have to try going through Cinema Tools per the similar issues noted in this conversation: http://forums.creativecow.net/thread/344/28007
    Curious to see what FCPX would do with this media, importing the 24p file to a 25 Project cause a noticeable shift in both time and pitch.
    I imported the time coded audio separately, and played it against the obviously speed and pitched changed video with embedded audio. The files did not sync.
    The audio remained in time and pitch, while the video didn't. So the audio tc doesn't seem to effect playback in FCPX, but video definitely does, and it seems rather buggy.
    So, if your video is 24.0 and your audio is 23.98 and you are in a 23.98 timeline, FCPX might be changing the speed of the video without really reporting it. Resetting speed doesn't do anything, hitting "automatic speed" screws it up a bit more (it goes the wrong way). Changing the speed to something like 96% (FCPX reports 96% but I know it's really ((24000/1001)/25) which is just short of 96%. Turning off the "preserve pitch" checkbox actually pitched the audio back to normal.
    I didn't create the 24.0 vs 23.9 media that you have, but perhaps you are having similar issues, or a different combination/permutation therein.
    But to answer your question, the time coded audio was not changed, only embedded audio.
    and
    But here some notes which makes things hopefully clearer.
    Resampling and changing playback speed are two totally different things.
    Samplerate for audio is the same as fps for video (not dpi for video) so let's call it sps.
    You can record audio at any sampling rate. But let's take 48 kHz and 32 kHz here.
    Record 60 seconds. Once recorded both files as stand alone files will play 60 seconds.
    But forced to play back in a NLE timeline with a fixed sps of 48 the first file will playback correctly. The second one will play at 2/3 of the time (32/48). The other way round the 48 sps file will play longer in a 32 sps timeline.
    Now for those poor guys who have to work with NTSC:
    A real world second is not a second in NTSC video world. Its 1001/1000 seconds.
    So selecting a 48k sps audio preset in a timeline preset means that a real world audio of 60 seconds is only 1000/1001x60. That means that those 60 seconds are only 59.94 seconds long. Its too short.
    One way - if you stay strictly in NTSC - is to record audio with 48048 Hz. This way a real world 1 second audio will match a 1 second NTSC video.
    Next option with BWAVE files is to change the playback settings in the BEXT header of the file. This won't resample the file!!!
    Now about the TC. BWAVE doesn't have a TC in a way you're used when handling video. It has a timestamp in the header. This timestamp contains the Samples after Midnight. Based on that the NLE will convert this to TC which can be displayed. So in NTSC world this might give a wrong interpretation.
    For example if you have a "Start TC" of 00:10:00:00 (thats what you see on your audio recorder) it means that using 48kHz the timestamp is at 600x48,000 = 28,800,000 samples. Since the real sampling rate in the timeline though is 48048 Hz you have to divide the source stamp by this number. This results in 9.99000999000999 minutes. So for a 23.976 fps project this is a TC of 00:09:59:10.
    So setting the Bext header and/or iXML chunk to the correct playback speed will keep everything intact. Again this is without resampling!
    Using an AIFF there aren't these options.
    So you can edit all the stuff without resampling when using BWAVE. But resampling will happen when you export a final movie.

  • How do I change the speed of the Final Cut Pro X "Ticker" Title option?

    I am moving from iMovie to Final Cut Pro X.  I used to use the "ticker" title option all the time in iMovie, but when I utilize it in Final Cut Pro X, it scrawls really slow and only shows the first line of text before the video ends.  How do I adjust the speed of this option?

    This Motion template effect isn't very useful at the moment.
    Sadly, the only way of changing the speed is to modify the effect in Motion.
    The speed is designed to get the word 'Information' at the default size and default typeface across the screen over the duration of the clip. If you add more text, or change its size, the text will not move off the edge of the screen by the end of the duration of the generator.

  • How to change the speed of a clip without frame blending?

    Hi,
    I changed the speed of a clip to 200%. I expected Premiere to drop every second frame. Instead, there is some frame blending making my progressive footage interlaced. For some reason, the frame blending cannot be disabled by using the Use Frame Blending option.
    How can I make Premiere simply dropping every 2nd frame?
    Thanks in advance!

  • How do I change the speed of a video clip after making it a Smart Object?

    In order to apply the same Camera Raw filter to every segment of a clip I was going to split multiple times, I converted the whole clip to a Smart Object, applied my Camera Raw filter settings, and then split the clip and deleted some portions.  Now I want to make certain portions of those clips slow-motion, but even if I right-click on the right side of the layer and select "Clear Smart Filters", all I see when I right-click on the clip in the timeline are the motion options; I can no longer change the speed or the audio.  Is there a way to do this without having to make all the cuts in the beginning, changing the speed and the audio, and then having to go back and convert each individual segment into a smart object and then apply the same ACR filter to each one?

    Brett,
    Thanks for addressing this question.  I tried it and see that the embedded file is the entire clip that I started with, not the trimmed version that I turned into a SO, but at least I could go back and make a change that way in a pinch. 
    If you wouldn't mind looking at this video between :50 and 1:40, and tell me if you think that AE or PP would give me significantly better results in the jumping segments where I slowed it down to 25%:  2014-06-26 And the last thing I expected to see jump out of the box was Albert Einstein! on Vimeo.  I am trying to keep my expenses down by only using PS CC for video editing, and love the Camera Raw filter capabilities.  By using PS CC it also lets me lay down my audio and edit to the audio w/o, as Mylenium suggested, outputting my file from PS CC into either AE or PP to do the slow-mo part. 
    Thanks again for your help!

  • How can I change the speed of a video clip?

    hi, I'm a new user of iMovie 08.
    I fail to find the function button that can make a video clip slow down or faster, such as change the speed to 60% of the normal speed,etc.
    I know iMovie 06 has this function,it's in video FX,duration,speed...but I can't find the menu in iMovie08.
    Is there anyone knows where it is?
    many thanks!

    Upgrade to iMovie 06.
    Slow / Fast Motion is easy with iMovie 06.
    iMovie 06 is a free download to iLife 08 owners. (THEY WANT YOU TO HAVE IT!)

  • How can I change the speed of a stepper motor?

    HSI bipolar Linear Actuator Size14, HSI Chopper Driver 40105, NI PCI-6052E, NI SC-2345, 2 SCC-DO01 modules, and SCC-FT01
    The motor works at one speed with a boolean array input, using the SCC-DO01.  But I need to be able to change the speed of the motor.  Specifically it needs to operate on several frequencies of functions of as displacement vs. time, such as sine wave, triangle wave, and square wave.  I tried to find information about using a digital pulse train but had no luck.  Is it even possible to accomplish with this hardware?
    Message Edited by Draben on 01-22-2006 09:43 PM

    In general E-Series DAQ-boards like the PCI-6052E are not very good for motion control tasks. The 6052E doesn't provide hardware timed digital I/Os so you can control the digital lines only by software. This is both slow and inaccurate as long as you are running the board under a non-deterministic OS like Windows.
    On a real-time OS the jitter would be better but still the frequency would be low and it would still be hard to program accurate acceleration and deceleration ramps.
    If you use the counter/timer instead of the digital I/Os you could reach higher velocities and a much better timing accuracy but it would be even harder to program acceleration/deceleration ramps which you will need if you want to reach higher velocities with your stepper motor. Additionally for motion control applications you may want features like limit switch monitoring and following error tracking which require again real-time capabilities.
    With this said I don't recommend the usage of a multifunction DAQ board as a motion control board. Please have a look at the NI motion control boards like the PCI-7332 which does all the motion I/O and trajectory control onboard.

  • My performance is very slow when I run graphs. How do I increase the speed at which I can do other things while the data is being updated and displayed on the graphs?

    I am doing an an aquisition and displaying the data on graphs. When I run the program it is slow. I think because I have the number of scans to read associated with my scan rate. It takes the number of seconds I want to display on the chart times the scan rate and feeds that into the number of samples to read at a time from the AI read. The problem is that it stalls until the data points are aquired and displayed so I cannot click or change values on the front panel until the updates occur on the graph. What can I do to be able to help this?

  • Changing the speed of the ethernet card

    Referring to this topic I posted earlier: http://discussions.apple.com/thread.jspa?threadID=568098&tstart=0
    I called my ISP, and they could only think of one thing: that there is a conflict between my MacBook's fast ethernet card and my old DSL box (that is capable of only 10 Mb/s).
    So, they suggested I try to change the speed of my ethernet card to 10 Mb/s.
    The problem is, how do I do it?

    I think your ethernet builtin is downgrade compatible, which mean it will run on 10 mbps too without you have to changed the speed.
    It is the first time I hear that we should adjust the transfer rate to lower setting.
    If your ethernet card max is 10 mbps and you want to use 100 mbps, than you must change the ethernet card or use other external ethernet card, not the other way around.
    Good Luck

    What version of Premiere Elements and on what computer operating system?
    Please review the following that I excerpted from an older post here regarding Adobe's PRE_help comments about Hollywood Effect and mention of
    Red Noir. Does any of the following apply to any of what is happening to you.
    - Whenever I try to add an effect from the Hollywood Looks menu, it brings up a warning that all my previous effects on that clip will be deleted. However it will let me add those same effects *after* applying Hollywood Looks.
    This is because of how the Hollywood Looks are designed to be used. Since these are effect presets (multiple effects in combination) that result in a specific "look"; they are best applied in isolation. If any previous effect is applied and we still allow a Hollywood effect to be applied, we will not be able to see what the effect does clearly. For e.g. if you already have a Gaussian Blur effect applied to your clip, and then we allow you to apply the "Red Noir" Hollywood effect, the fact that the "Reds" in the scenes will be highlighted and the others converted to B/W will not be clearly seen since the content is already blurred out. So any previously applied effects was designed to be removed. This holds good even if you apply a Hollywood look "on top of" another one. The previous one will be replaced. Having said that, you can customize the look further by either tweaking an already applied filter or by adding a newer effect on top. That is the reason you can apply an effect on top of the Hollywood Effects and not vice versa.
    Please review and consider and then we can proceed from there if necessary.

  • Can i change the speed of the track?

    I got one track that instrumental and other one is vocal..and i hope someone can teach me how to change the speed of the vocal in garageband.thanks!

    "in every track you have the option to check or uncheck the 'follow tempo and pitch' option"
    This does not appear anywhere in the interface.
    "you have to change the region's color to purple first)."
    The suggested (obscure) key combo does nothing.
    If you delete all tracks and then drag a wave file from Finder into your project, GarageBand messes up both the playback speed and pitch. Furthermore, the so-called track "track info" on the right makes no sense. It always displays "Real Instrument" and "Master Track", even when this is not the type of track you're working with.
