What attributes must have a loop-ready audio file?

Hi! I perform songs for video production and have doubts about how must I edit my songs so as to be useful for video production, specially when they have to be looped.
A few days ago one of my files was rejected because it has a tempo of 99.9732 bpm instead 100 bpm. How much precise does the tempo must be? Does it really matters?
Do video producers really need the looping properties to be embedded in the file info tags (wave properties)? Like Loop info, Sampler tags...

No they don't, and on top of that, they are being complete ***holes, by the sound of it. Fortunately there's a fix that should work:
Go to File>File Info>Loop Info and set it to Loop. Then edit the number of beats in the piece (you will have to play around with the decimal place values here) until the grey tempo box says exactly 100 beats/minute. Then save the file (this updates the metadata) and resubmit it.
I don't think it's easily possible by ear to estimate tempo to within 1 bpm, never mind a couple of decimal places, so you are absolutely going to get away with this!

    Actually, I believe the drivers that are available on the NI website are licened for upgrades only. If the hardware came with an NI-488.2 driver, you can upgrade that to the latest version with the link above.
    If your purchase did not include a software license (the hardware is sold separately from the hardware due to single- and multi-user license options), you need to purchase a license of NI-488.2.

    The part numbers for the single and multi-user license for Windows are 778598-02 and 778598-01. Other operating systems are listed as well.

  • How do I loop external audio files?

    I would like to have an external file (actually, one of several randomly selected files, but I can handle that) play and loop but I have yet to understand how to do the latter.  My code works great for playing the file through one time, but when playback completes, it's done.  How do I loop the audio?  Is there perhaps a listener that can wait for the file to finish playing, then call a function to play the sound again?

    I sincerely thank you for the helpful advice.  It answers the question I asked, and I'll mark it as such, but it leaves me hanging (I think) with regard to what I wanted to ask.
    I will rephrase the question and put the emphasis where I should have put it to begin with:
    Is there an event that fires when an audio file finishes playing so that I can select another audio file to begin the process of loading and streaming again?  The loop solution seems to fall short of accomplishing that goal since it will only loop the same file.
    Also, I'm actually using a SoundChannel object, and don't know how to use the number-of-loops argument in this context.  Here is the code I use:
    var mysound:URLRequest = new URLRequest('../_RefFiles/bkgdmusic.mp3');
    var sound:Sound = new Sound();
    var controller:SoundChannel;
    var play_mc:StartPlayer = new StartPlayer(); //gif image
    var stop_mc:StopPlayer = new StopPlayer(); //gif image
    var context:SoundLoaderContext = new SoundLoaderContext(5000, true);
    //sound.addEventListener(Event.COMPLETE, soundLoaded);
    sound.load(mysound, context);
    //function soundLoaded(evt:Event):void
            controller = sound.play(0,200); //Doesn't work...
            controller.stop();
            gotoAndPlay("Play");
    stop();
    ["Play" frame]
    controller = sound.play();
    addChild(stop_mc);
    stop_mc.y=-7;
    stop_mc.addEventListener(MouseEvent.CLICK, stopSound);
    function playSound(evt:MouseEvent):void
        controller = sound.play();
        removeChild(play_mc);
        addChild(stop_mc);
        stop_mc.y = -7;
        stop_mc.addEventListener(MouseEvent.CLICK, stopSound);
        play_mc.removeEventListener(MouseEvent.CLICK, playSound);
    function stopSound(evt:MouseEvent):void
        controller.stop();
        removeChild(stop_mc);
        addChild(play_mc);
        play_mc.y = -7;
        play_mc.addEventListener(MouseEvent.CLICK, playSound);
        stop_mc.removeEventListener(MouseEvent.CLICK, stopSound);
    stop();

  • More than one loop in audio file

    Please, allow more than one loop in a wave file. This functionality was present in the Adobe Audition 3.0, but it is gone now. The sampler tab is gone from the metadata. Please, bring it back. Even though, the user can set more than one region marker in the wave file, only one of them is internally set to be understood as a loop and there is no way how to set more loops in a wave file. Please add this functionality back into the Audition.

    Only one audio file can be used in a Lightroom slideshow.
    You'll have to combine multiple songs into a single audio file (e.g. using Audition) then use the single audio file in the Lightroom slideshow.
    For more flexibility, you can use commercial software such as ProShow Web, Gold or Producer which comes with a free Lightroom plugin

  • Must have 1 Easy Set Up File?

    I posted before about having lost my serial number and being unable to start my FCE. I got a serial number from Apple and I entered it where asked. Then Final Cut Express began to load and an error message popped up stating "Unable to start Final Cut Express. You must have at least 1 Easy Set Up File. Please re-install Final Cut Express and try again."
    My problem is that I no longer have my Final Cut disc. Any ideas on how to get my FCE to work?

    You should contact Apple. You must uninstall and reinstall the application, and the only way to do that is from a disc.

  • Some Audio files have stopped producing sound - audio files not working

    Hello
    I recently noticed on a number of my projects that a few audio tracks have stopped playing back. This is very frustrating as I don't think I have done anything to change them.
    For instance, the snare drum audio track that I have doesn't play anymore. The track is not greyed out, and it worked before, and I see the waveform when I zoom in. The file is still in my audio bin and if I play from there, I can hear it. I don't have the track muted, or the fader down, and it's output is set to my MOTU Output just like the rest of the tracks that do work.
    I also have another project with various sound FX placed and timed just right, and a few tracks have done the same problem. I don't want to have to re-align them all again.
    Please help!

    Do you have two regions of audio assigned to the same audio track?. Create a 2nd audio track directly below the questionable one on the arrange page. Slide the silent audio object down to the next track. Does it play then?
    Is the audio track going to the proper outputs? If you are using a multi channel interface box like Motu 828, they could be assigned to the wrong output.
    Can you create more audio tracks, and drag them out of the audio bin? do they work now.. Two years back, I was having that problem, don't remember how it got rectified other than creating new audio tracks and sliding the audio onto them.

  • What is the full name of the audio file type used in iTunes 10.3.1.  Are they MP3 files?

    Is this a file type that came into being BEFORE OR AFTER MP3?   Are these MPEG audio file layer 1 or layer 2?  Just curious.....

  • Is there a way to have more than one audio file play in a slideshow?

    I know how to add one audio file to play as the pictures go through, but is there a way to get a second audio file to play in the same slideshow??

    Make an album in iTunes with the songs you want to play in your slideshow. Then drag the album to the audio well of your iDVD slideshow.

  • What is the best way to download audio files?

    I am building a website for a church.  How do I put the weekly audio sermons on the site, so that the files don't take forever to download?
    I had a link with quicktime, but someone said they didn't have that plug-in, so I have embedded the files.
    ...what is the most popular and fast way for people to hear the sermons?
    I have split up the pages.
    I was hoping for one like, https://crosspointelpaso.ctsmemberconnect.net/sermon-ctrl.do?view=0&grpId=26073
    This is where I am now...http://www.estevanfaithlutheran.com/listentosermonsonline.html
    Thank you.
    Em

    The site that you referenced is using mp3 for the sermon audios...  if you look at the code for one of the links it is this:
    <a href="https://f1.ctsmemberconnect.net/garoupdb/O-0000000937/G-0000026073/audio/Sep 21 2008.mp3" title="" target="_blank">What Is God Looking At?</a>
    It then depends on what the client machine uses to run mp3s as to how they open, automaticallly or the viewer is asked whether they want to open the file using their mp3 player.  Probably more widespread than using quicktime.

  • Looping an Audio file.

    I have one song inserted in a page. It was inserted using the Media browser. It is an .m4a file at 9.3MB. The Page name in the site index is "6 Photos"
    In the published file (local at this time), the files created for this page are:
    6_Photos.html
    6Photosfiles (a folder) *
    6_PhotosMoz.css
    6_PhotosIE.css
    6_Photos.css
    6_Photos.js
    My question is three-fold:
    1 - Can the system generated coding be amended to create a loop?
    2 - If "yes";
    a) in which of the 5 pages will the coding be found?
    b) what is the coding - before and after?

    There's no editing needed. Select the file on the page and go to the Inspector/Quicktime pane and check the autoplay and loop checkboxes.
    As a courtesy to visitors I suggest setting the volume down low so as not to blast out any unsuspecting visitor that might have their computer volume up high unknowingly. They can set the volume via the controller to their preference.

  • Why do I have to re-sync audio files every time I republish?

    after I update my presentation and republish it, the audio links are broken. The only way I know how to fix it is to go slide-by-slide and add the audio back in. Is there a way to re-publish without losing audio?

    Well, I was charging it and playing some music. I looked down, and the screen was bright White....I could not shut it off. I unplugged it and held down the buttons, it turned off and never turned back on again.
    It was extremely hot. Not enough to burn you, but sorta like a cup of coffee hot.
    They were not sure what happened, but i got a new (not refurbished) touch.
    Wish I could figure out this registration thing though.

  • I have an audio file that plays automatically and I can't control it other than reduce the volume.  How do I turn it off?

    I have picked up an audio file that I can't control other than reduce the volume.  I don't know how to turn it off and it plays over any other audio.

    Is this an Apple installed audio clip?
    Have you checked to see if all of your browsers doesn't have a web page that is opened that has the audio? (Best thing is to quit all of your browsers to get that out of the way.) If it goes away, then find out which browser (if multiple), and then figure out what page or just close it if you wish.
    Once you get the browsers out of the way and the audio is still playing. Then quit other programs.

  • Where does Keynote store the audio files in a presentation

    I have slides with individual audio files. When I import or attach the file and then save the presentation, it changes the file name to .mov extension. Where does Keynote store those files? I would like to edit the saved Keynote version, but cannot locate the .mov file!

    I'm not exactly sure of what you want to do, and I'm not sure if my answer is the most efficient, or even wholly correct, but here goes ...
    When you save a KN presentation (a KN doc) which includes an audio (or movie) file, you can save it 2 (3?) ways: either without or with the file being copied into the document, or as a "package". In a test file I just made with 3 white slides (title, slide with song, second slide with song) the results:
    without: 3.8 MB; with: 9.4 MB; package: 9.4 MB. The essential difference, aside from size, is that if saved without, if you play the KN on another machine which doesn't have those audio files on it, the audio won't be there. To make the KN truly portable, you must save with, or as a package. (I'm not too sure of the concept of package in KN. In PP, saving as a package means you end up with a folder, which contains the PP and the media files, each as separate entities. Saving a KN package yields not a folder but a file, which looks to me identical to the result achieved by simply saving with, and seems to behave identically, as well.) The audio file you used will in any case remain where it was before you used it, but, if the KN doc is saved with, or as a package, a copy of it will go into the KN doc.
    But then, what do you mean by "edit"? What do you want to edit, the KN presentation, or the audio file within it? If the former, I don't understand where the problem might be. If the latter: using the QT inspector within KN, you can change the length of the audio file (where in the song it starts and stops), whether to start it on click, or automatically after transition, or to loop it. If you wanted to do some other, more exotic audio editing, like reverbs or other effects, I'd do that on (a copy of) the original audio file (found wherever it was before) with another app (GarageBand, for instance), and then I'd replace the first, non-edited, version of the audio file in the KN doc with that.
    Have I missed something?
