Split MP3 file into multiple MP3 files

I've been through the help section and is till cant seem to figure out how to split a large (2 hour) mp3 file into multiple mp3 files.
I have a 2 hour MP3 recording (Stereo not mono), and I have added markers (by simply pressing keyboard shortcut 'M' to add marker), but now I would like to know how to split that one mp3 files into multiple files from the markers which I have made...
All my marker types are "Cue" when i pressed 'M' at the locations I want the track to end/start

You didn't say which version of the program you're using, but in general, there is a way to do this by adding one additional cue at the very end of the file, then "merging" the cues (which converts the space between each cue into a "range"), and batch processing each range out to a separate file.  (Make sure there's a cue at the beginning of the file, or at least the first material you want in a new file.)
Now that you've done all that work, I'm going to tell you that what you're doing is probably a bad idea.  Opening any mp3 in Audition and resaving back to mp3 means you've doubled the losses and distortion inherent with the mp3 compression.  Audition can't do lossless editing of mp3s.  The bottom line: are you really splitting the file, and does the result have to be mp3 format?  If saving to a (wave file, or any other lossless format, then what I'm saying doesn't matter.
In any case, "mp3 Direct Cut" is a terrific freeware program that does lossless mp3 editing, and I'd highly recommend you try it.  It's saved my neck a number of times.  See http://www.mpesch3.de.

  • HT201066 How can I split a long recording audio file into multiple audio files?

    Hi,
    How can I split a long recording audio file into multiple audio files?
    With Windows I was using Nero software, which is not available for Mac. Is there any similar app for free for Mac?
    Thanks!

    Hello ingiorgio
    You can import the track into GarageBand and then split the tracks there. Once that it is done you can highlight the ruler section and then share the song to iTunes to get them separated out.

  • Break .mov file into multiple jpeg files

    Hello all,
    I've already put together a program that jams multiple jpegs into a .mov file, but is it possible to do the same thing in reverse?
    I have a .mov file captured from a camera. I need to decompose it into a ton of jpegs.
    the purpose is that I have a real-world video file of an event occuring. I have a computer simulation of the same event. I want to overlay the two into a single video.
    My basic plan was to decompose the real-world .mov file into jpegs, then take each individual jpeg and draw my simulation stuff on top of it. Then I would combine it all back together into a movie again.
    Another possibility...somehow use processors? I'm not sure how to do all that and I think this solution is simpler if I can somehow figure out how to split the file.
    Thanks for you input.

    captfoss...how did you ever become so knowledgeable? Is it your job to answer these forums?
    I'm just very impressed, is all.About a year ago, I thought up the idea of creating a web site where musicians / music fans could go, create a chatroom, and pay music for people live over the net. Through the course of research, I found out that the only 2 ways of doing an application like that were JMF or Adobe Flex/Flash... Seeing as how I'm a Java coder by profession (and hate Flash applications), the choice of which to go with was easy...
    And then I realized that JMF is, on the surface, quite complicated and while these Sun forums are full of experts on just about everything else, there weren't really any JMF experts. So I sat down, went through the JMF example code peice by peice, wrote out the components, figured out what each one did, and I wrote my application from scratch. I wanted to make sure I understood my app, of course, and wasn't just throwing out something "that worked" because, well, all those years of college told me that's a bad plan.
    Anyway, I figured out the nuts and bolts of my project, and then just started trying to answer the questions on this forum that were going unanswered...and that's how I become so knowledgable, because with something like JMF, whenever you work with someone, a lot of times you learn nearly as much as they do.
    Plus, I most just like helping people and JMF had a giant opening for a resident expert...

    In the example, I've given 5 records to split. If you want 50 records to split, then instead of 5 give 50 in the constant.

  • How to Split Master File into Multiple Small Files?

    Sorry if this has been addressed - I'm having a hard time finding the answer.
    I'm using FCE 4.0. I taped 4 hours of material and need to deliver the footage to someone in discrete chunks. I tried to do in/out capture but for some reason that wasn't working - something to do with the timecode. So I did full tape dumps.
    So now I have 4 huge files (4 miniDV tapes) that are too big to deliver as-is. I used DV Start/Stop Detect to set markers, then used that to create sub-clips. But of course this doesn't actually affect the master scratch files.
    What's the best way to convert these sub-clips to individual mov files? If I do an export of each file ("Using QuickTime Conversion..."), don't I risk losing information or possibly quality? Isn't there some way to highlight all my sub-clips in the bin and say "Mega-Chop Activate!" or something?
    Or, taking a step or two back, if there's another way I should've approached this, please let me know. There'll be more. Plenty more.
    Thank you.

    I'm burning mov source to DVD for FC editing by someone else.
    Your second set of questions actually gives me some ideas - that's exactly what I'm trying to figure out.
    As an example, let's say 1 tape, i.e. 1 master file, holds 5 interviews. I want to deliver 5 individual files/clips, say 3 on DVD A, 2 on DVD B. (Assume for the sake of argument that the math works out and there's no other way to deliver this.)
    - Does creating a different project for each "chunk" result in a different file in the scratch folder that can be burned to DVD?
    - Does "Print to Video" create QT files? I thought this output back onto tape.
    - By "Export to QuickTime" are you referring to Export->QuickTime Movie (as opposed to Export->Using QuickTime Conversion)?
    - Does Export->QuickTime Movie result in lossy conversion or does it automatically retain the original capture quality?
    - Is there a way to do all 5 exports at once or must they be done individually?
    Thanks for the fast response!

  • How to split large video files into multiple individual clips by date

    Hello. I'm looking for a freeware/shareware program (if one exists, or willing to pay for one if it does this well) that will:
    1) Analyze a large AVI file identifying the start/start points of each segment of video and the dates the video segments were shot.
    2) Then allow me to organize (for example, join 2 or more segments together if it's a video with a lot of start/stop points during the same shot) the segments identified in step 1 into logical clips that could be split apart from the 1 large AVI file.
    3) Lastly, it would split my one large AVI file into the multiple clips or files that I identified in step 2.
    A piece of software called FootTrack does a great job analyzing AVI files as I describe in steps 1 & 2, but it doesn't allow you to split or export the one avi file into multiple avi files.
    I really don't want to have to do this one clip at a time, I've got to believe there's a program out there that will automate this process for me.
    Thanks

    I don't know of a way to automate it. I just did about 15 years worth. It wasn't too hard. I use an application called mpegstreamclip. Its very easy and free to download either from the apple site or direct from its site.

    Bascically you set the in and out points with the i and o keys and export.

  • Can i convert AIFF audio file into an MP3 file please?

    Can i convert AIFF audio file into an MP3 file please? I will be doing this on an imac 2008 model. thank you for help!

    Since this is the Logic forum and you may be working in Logic, you dont even need iTunes. To convert Aiff to MP3:
    1 - Go to the Bin>Audio Files
    2 - Select the Audio File you want to convert ( and not a region or edit of it)
    3 - Go to Audio File next to the Link icon ( Audio - Edit - View ) and down the menu to Copy/Convert.. gives lots of options

  • Adapter file sender doesn't split file into multiple message

    Hi everybody.
    We are in PI 7.0 SP10.
    In adapter file sender, I want to split a file into multiple file.
    We use protocole "file content conversion"
    in the field "recordset per message", I put the value 10 to test.
    The file content 30 records .
    The result we have is the treatment is not split into multiple message .
    The treatment is made but with one message.
    I need  to treat big files.
    Is there some one who have an idea  why t doesn't work ?
    Thanks in advance for your help.
    Regards
    Edited by: Eric  KOralewski on Jun 25, 2009 3:14 PM

    Hi,
    have you specified recordset name......if not, then specify it.............
    in recordset structure, specify like RECORD,1 and not RECORD,*
    again test your scenario......if still your file data is not getting split, then ask your basis guys to do a full CPACache refresh using PIDIRUSER..........your basis guys will know how to do it..........then again test your scneario............

  • Split file into multiple Instance of an IDoc .

    My file (only one file) in the file system contains multiple entities(lets say sales order).Now using File adapter I want to transfer this file into XI and want XI to create multiple instance of an IDoc(for each sales order) and send them to the target system one by one.
    Alternatively can I split the file into multiple entities(sales order) in the file adapter (using dispatcher for e.g) and send multiple message to the configured XI automatically.
    Is any of the alternative possible in XI20.
    Any responce would be highly appreciated.
    Regards,
    Bikky.

    Hi,
    You can get the file adapter to split the file without the need for a dispatcher user exit.  The config goes a little like this:
    mode=FILE2XMBWITHSTRUCTURECONVERSION
    xml.recordsetStructure=SALES_ORDER,1
    xml.recordsetsPerMessage=1
    This last parameter ensures each sales order is posted to the integration engine as a separate message.  Therefore a separate Idoc is created for each.
    Hope this helps.

    07/04/2013,No,PeopleBiz
    07/04/2013,No,PeopleBiz
    Any help would be greatly appreciated

    I think this might be what you want:
    Import-Csv applications.csv |
    Group Application |
    foreach {
    $_.Group | Export-Csv "$($_.Name).csv" -NoTypeInformation
    [string](0..33|%{[char][int](46+("686552495351636652556262185355647068516270555358646562655775 0645570").substring(($_*2),2))})-replace " "
    Very nice! 4x faster..

  • Splitting of a CSV File with Multiple Records into Multiple XML File

    Dear All,
    <b> I am doing a Scenario of CSV to XML Files. I am using BPM for the same. My incoming CSV File has got multiple records. I want to break this Multiple records into Multiple XML Files having one record each.</b>
    Can someone suggest how can I break this rather Split this into Multiple XML Files.
    Is Multimapping absoltely necesaary for this. Can't we do this without Multimapping. Can we have some workaround in the FCC parameters that we use in the Integration Directory.
    Kindly reply ASAP. Thanks a lot to all in anticipation.
    Pls Help.

    Dear All,
    I am trying to do the Multimapping, and have 0....unbounded also. Someways it is not working.
    <b>
    Smitha please tell me one thing...Assigning the Recordsets per Message to 1, does it mean that it will write multiple XML Files as I want.</b>
    Also I am usinf Set to Read only. So once the File is read it becomes RA from A. Then will it write the other Records.
    I have to use a BPM because there are certain dependencies that are there for the entire Process Flow. I cannot do without a BPM.
    Awaiting a reply. Thanks a lot in anticipation.

  • Splitting single video into multiple files - workflow improvements?

    I regularly need to split a single video into multiple separate files that are used by other programs.  I'm using Premiere Pro CS4 for a number of reasons including the ability to easily and accurately select a scene by individual frames, native audio and video effects/filters, and the ability to import and export various video types.  I'm open to using other tools, but I haven't yet found one that is even close to Premiere Pro when it comes to accurately selecting split points.
    I'm not a Premiere Pro expert.  I have been doing this for about four months and have read many resources (books, forum posts, help guides) to refine the workflow I'm currently using.  My question:  does anyone know any improvements that might save me time/keystrokes.
    Current workflow:
    I've bound F8 to File > Export > Media
    Import video file
    Open in source monitor
    Set In and Out points for scene in source monitor
    Ctrl-drag from source monitor to Project Panel (creates a subclip)
    Repeat 3 and 4 for all scenes/subclips
    Select all subclips from Project Panel and drag to timeline
    Set work area bar to first subclip in timeline by the following four keystrokes:  Home, Alt-[, PageDown, Alt-]
    Type F8 (File > Export > Media shortcut).  Type output file name, click OK and the first subclip is put in the AME queue
    For the remaining subclips, type: Alt-[, PageDown, Alt-], F8, output file name, OK and repeat until done
    Any thoughts/ideas on workflow improvements?
    Thank you!

    Thank you Hunt.
    For the sake of brevity, I didn't include all of the details about the various aspects of the projects.
    Early on I was doing what you suggested and yes, it is a little quicker.  I learned (painfully) a couple of months later that I sometimes have to go back and adjust the clips and this method (trim to timeline with no subclips) resulted in quite a bit of duplicate effort (to reobtain start/stop points).  I've since learned that managing the "scenes" as subclips in topical bins allows me to go back and make adjustments, long after I've totally forgotten about the project content, without a lot of unnecessary reworking.
