Question

Splitting Stereo Channels into seperate tracks

  • September 25, 2008

I have a stereo audio track which I have pulled from an AVI file in prem pro. The left channel has voice from a radio mic while the right channel is the camera mic with general audio. I need to seperate the two channels so I can use the voice audio when its needed.

So my question is how do u do this?

I'm a beginner user of AA though I have owned veris versions for some years, just never had the time to get right into it until now. I've have spent the last couple of days digging through help menus and manuals trying to solve this problem. Usually I'd use hardware to do a work around but I figured I might as well start using the software.

Any help would be appreciated...
Sorry if this is a silly noob question.

    Load the stereo track into Waveform View.  Click the little L to the right of the upper half of the waveform and it will mute the left channel.  Click File>Save As and save the right channel.  Then unmute L and repeat the procedure with the little R to the right of the lower half of the waveform.

    This is faster than working in Multitrack, I think.

    I realize this thread has gone dormant, but having begun putting Premiere Pro CS5 through some paces and needing to split a stereo audio track in order to treat each side differently, I wonder why not

    A) duplicate the stereo audio track and place the result in the next available audio channel, then

    B) pan track one all the way to either the L or R, followed by

    C) pan track two all the way opposite

    Voilá! Separate tracks for processing!

    However, the best and most obvious choice is an editing app that simply allows one to de-couple the stereo track in the first place -- like Final Cut Pro.

    That said, I am impressed with the speed at which PP works (aaaahhh, 64-bit app). Otherwise, underwhelmed by the relative paucity of functionality of the app compared with FCP.

    Audition does this easily and always has done although not a video editing app and not available for Mac users except when used in a Windows emulation.

    Good to know that Audition has that capability, although for we who edit, bouncing out to a second app simply for the purpose of being able to perform simple operations on accompanying audio is inefficient.

    Having no interest in working with windows os nor emulating same, Audition is, for the foreseeable future, off the table for this correspondent. Perhaps down the road.

    Happy editing!

    That's great - I've renamed it to the way it was, and put it back in the archive. So the original link still works, and it's a simple matter of right-clicking on that and using Save As.

    OK, I've rummaged around this laptop & found the files. You'll now find them here:-

    http://www.bunyipmusic.com/s2m.zip

    stereo2mono.exe can be run from the command line, e.g.

    stereo2mono wavefile1.wav wavefile2.wav ...

    or you can drag several wave files to stereo2mono.exe (or a shortcut to the program). If you wish to use it this way, I have provided an icon.

    Either way windows will limit the number of files to 10 or so, depending mainly on the length of their names. Note that the program is not a DOS program, but must be run from the command line in windows (NT, XP etc.), although just to be confusing we sometimes call this DOS!

    Heading off into the unknown tomorrow, so internet access will be rather patchy.

    I got a message back from the site manager which says "If it isn't there, it wasn't on the FTP site when I switched hosts."

    So Alan, if you are presently able to, you need to put the file back!

    >I will contact the owner of it...

    I've now heard back from the server owner, and the server is now working again - it was moved to a new ISP and not reset, apparently.

    What's not so good is that Alan's folder doesn't appear to be there, so a little more remedial work is required, I think.

    For reasons not yet ascertained, you can't download the zip file at present. Well, I can't here, anyway, because the download site password doesn't appear to work (and it certainly did before). I will contact the owner of it...

    excellent Alan, I believe Adobe should give you a wad of cash (USD please...) and incorporate your functionality into Audition.

    I know music people don't really "get" why you need to split stereo's, but people working in radio and (especially) film/video need to do it all the time and it's quite frustrating to not have a clear & simple workflow in AA3.

    In the thread shown below, in the entry dated 18th July 2007 I posted a link to a program I created to perform this task.

    http://www.audiomastersforum.net/amforum/index.php/topic,6374

    I've had very little feedback about this, but it works for me.

    Note:

    I don't know if the version posted is the latest version (the first version I posted may have had a problem, can't remember).

    I am currently in Scotland and won't return home to Australia until the end of November, so can't provide any help for several weeks.

    Cheers,
    Alan
