Splitting Stereo Tracks

I recently captured footage and unfortunatley my microphone only captured in mono, so the sound is only on the A2 audio track and there is nothing on the A1 audio track. I am trying to make these track independent so that i can copy the A2 audio into A1, but I cannot figure out how to do this. Can anyone offer assistance?

There is no need to double up the tracks.
If the audio is a stereo pair, select all the clips in the timeline you want to affect and press Opt-L to make them mono (a1/a2). Use Cmd-Shift-A to deselect all. Press the T key, for track select, and then hold the Option key and click on the track items you want to delete to select them. Delete the track contents. Select all the now mono clips with the T key and press Control-period to center the pan so the sound comes from between the speakers rather than from left or right.

  • Splitting stereo tracks to mono for separate editing?

    Does anyone know of a way to split a stereo track into two mono tracks inside of Logic Pro 8?
    I'll explain my problem, I have a track made from samples of a song. In the track that I recorded, there is one particular sound that I can't get rid of no matter how hard I try. I recorded the passage with the ESX24 in stereo and I noticed that the noise is only on the left track. My first solution was to pan the track all the way right, create a duplicate of that and pan it hard left. Unfortunately, it loses a lot of clarity and texture when I use this method..
    Looking on the forums, all I could find was instructions to bounce the tracks to split stereo, but I need them to form separate tracks within Logic so I can apply a LowPass filter to the problematic left track, then mix them back together as one stereo track later....
    Any suggestions?

    You guys are talking about different things. The OP says he's using an exs24 instrument with a sample that has a noise on one side of the stereo field of a SAMPLE not an audio region recorded into logic. Samples used by the EXS24 are not added to the audio bin, only into the EXS24's RAM. You could pan the instrument track to the side without the noise, and then output the result to a bus track that is set to MONO. That will pan your one sided sampler back to center. You can also bring the sample into logic (using the browser) and then split it as eriksimon suggested, and then create a new EXS24 instrument using only the good side of the sample.

  • How to split stereo track into 2 mono

    How to split a stereo audio track into two seperate mono tracks (Left, Right).
    (Have searched the manual..)

    Also, where you select mono or stereo for a track below the level meter you can click + hold and select L or R. Instead of bouncing, you can convert the files, for me this gives fewer room for error. Also disabling UTM works in some cases, but this is not ideal for every session.

  • Split audio tracks come back in as still stereo??

    Zoom recorded audio track.  Two interleaved tracks.  One side voice, the other side guitar.  The track comes in as a stereo track.  I export out the track as 'split'.  The exported result is two separate mono files.  One file is voice, the other file is guitar.  So far, so good.
    I bring the two separate mono tracks BACK into Logic ... and EACH ONE is still a stereo track with the voice and guitar on left and right respectively.
    I'm trying to figure out why Logic is doing this ... and what click I am missing that is causing it.
    All ears,
    Ben

    If the Logic 'mono' files are in the same folder - when I bring them into Logic, Logic somehow turns them back into stereo (no matter which I bring in, left or right).  If I take the Logic created mono files and re-export them with Quicktime 7, then they come into Logic as separate 'mono' files.
    If I separate the two mono files into different folders, then bring them in one at a time, they come in as separate 'mono' files.  When they are in the same folder, no such luck, they come in as two 'stereo' files, even though they SAY 'mono'.
    So Logic has some kind of unusual protocol where it somehow reads a split mono file as the original unsplit stereo file (if both files come from the same folder).
    Is there a way to alter this protocol???  I'm getting the 'logic' of why Logic does this.

  • How to SPLIT ONE STEREO TRACK'S L & R CHANNELS INTO TWO MONO CHANNELS

    Does anyone know if this is possible: How to SPLIT ONE STEREO TRACK'S L & R CHANNELS INTO TWO MONO CHANNELS?  There's got to be a way, but I just can't find out how.
    I recorded a podcast -- me and a guest, with each mic going to its own mono channel. When I opened it in Audition it mixed them into one stereo channel. 
    Thanks in advance for any help.
    Best,

    You're a big help! Thanks very much.  Simple yet I must be going blind because I didn't see that in the menu.
    Take care and THANKS AGAIN.

  • Split Stereo to Two Mono Tracks - Need Help

    We're having trouble with STP working with two non-stereo tracks.
    We have footage that we're editing in Final Cut Pro that was captured with two separate mics providing the audio. (A wireless lav and a shotgun.) The sequence is set up with two mono tracks.
    When sending the project to SoundTrack Pro, it's opened up as a pair of stereo tracks. We cannot find a way to edit just one of the tracks without it affecting both at the same time.
    How can we separate the tracks so they can be tweaked individually and then sent back to Final Cut Pro?
    Thanks for any help you can provide.

    ...and when doing that, make sure when you export, you don't fall over one of the many bugs in STP:
    You will probably find that the clip with the right channel selected actually plays the left channel after being exported (sound fine on the timeline - problem only on the exported file).
    The solution is to
    1) duplicate the stereo file and place on new track (as suggested)
    2) select left channel on first clip (control/right click the file)
    3) select second clip and swap the L and R channels around (Process-> swap channels)
    4) select left channel on first clip (control/right click the file)
    Oh the joys of STP!

  • Viewing stereo tracks in arrange window?

    Hello. I created an interleaved stereo audio file. But the track looks graphically like it's mono in the arrange window. Is there a way to have a graphical representation that it is a stereo file (like in Live, Pro Tools, Studio Vision, etc...)? (If I double click on the track, the file editor shows that it's stereo, but I want to see this in the arrange window.)
    It's got to be possible, right?
    A

    no it's not possible or even generally desirable.
    at least in PT, files are split stereo only. they are actually 2 mono files linked together. interleaved works differently. for editing, combined view of both sides as one waveform is actually better for editing unless you need to edit one side of the stereo file. in this case you will need to convert it to split stereo.
    the interleaved stereo file you see will show sidedness by projecting the channels either side of the mid point which is more than adequate generally. why would you need it to be different from that?

  • Is it possible to set up a split audio track....

    ...while recording and create 2 channels with their own effects settings. I have a Tascam US-122MKII audio interface. If one guitar is plugged into LEFT channel and one into RIGHT channel, can they be split up while recording?  I don't quite know if the TASCAM allows for this I'm not seeing anything in the manual and don't see wether LOGIC is capable of doing that? The idea is to record 2 guitars at once but split up the stereo into seperat tracks and then add effects so that each player has a different sound. The TASCAM allows 2 intruments ie: voice/guitar,or right and left XLR input but so far everything is imported to 1 stereo track...Any ideas on wether it's possible? Thanks everyone.

    Hi
    What I'm saying is:
    Make a new MONO audio track (use the + button). Assign it to input 1
    Make a second new MONO track, assign it to input 2
    Name both tracks, record-enable both tracks, and record.
    You could, of course, make both tracks in one go via the new track dialog box, and hav ethem automatically assigned to ascending inputs.

  • Splitting Stereo Files

    How do you split stereo files in Logic? Anyone? Whenever I import a stereo file, it comes as one interleaved track. I change the track to accept stereo files (at the bottom of the fader in the lower left hand corner) and even when I double-click on the file, I see two channels, yet I can't alter them. Is there a way to fix this? Please help. Thanks.

    How do you split stereo files in Logic?
    I see two channels, yet I can't alter them. Is there a way to fix this?
    Is your question: "How do I split a stereo interleaved file into two mono files with Logic?" or is your question "How do I use split stereo (dual-mono) files in Logic?"
    For the first, there are options in the audio window to convert and split files.
    If it's the second, then you can turn "Universal Track mode" OFF in your audio preferences - now all channels are mono and stereo files are controlled by two mono faders.
    However, working in this mode is kinda ugly and has some disadvantages, but if you prefer it, fair enough.
    Finally, if you just want to be able to process left and right channels of a stereo file independently, you can always route to a couple of busses and pan left or right to get the two halves, or duplicate your stereo track and select "Left channel only" and "Right channel only" by click holding on the O-OO stereo channel selector.
    Does that help?

  • (True) "Real" Stereo tracks converted to Mono after 5.1 update

    Hello:
    I have true stereo (as opposed to dual/centered mono) vocal and guitar tracks included in my most recent project. When I played everything back yesterday I noticed that all the "real" instruments had been converted to mono. I checked the source AIFF files and discovered they are still stereo. I typically record multiple vocal tracks and the export the resultant combined vocals (mono) and clean things up in Amadeus Pro. I often split the track, offset one channel, merge the channels and save the now-stereo file which gets imported back into GarageBand. This saves me from having literally hundreds of iso vocal tracks to deal with and it also opens up the vocals by spreading them across the stereo image.
    The unwanted stereo to mono conversion has happened once or twice the past and I've never really figured out a remedy other than reimporting the AIFF files.
    I was simply curious if anyone had experienced this phenomenon before and discovered a fix before I began the task of reimporting the stereo tracks. Btw, earlier versions of the project were unaffected by the update (if indeed it was the 5.1 update that cause the problem)—so it appears that only the current working project was altered.
    Thanks!
    ~Huck

    I discovered I had only one option (mono) until I unplugged my Mbox and selected System Setting as input source in GarageBand. At that point, stereo became available as a option and I went track by track enabling stereo playback. Thank you very much for your assistance! While I'm not entirely certain why having my Mbox selected as the input source changed all my "real" tracks to mono, at least I don't need to go through the hassle of re-importing the source material. I need to use the Mbox for guitar and bass tracks, so hopefully this was a one-time oddity.
    Again, thank you for your help!

  • Editing Stereo Tracks

    Here's my situation; I want to be able to edit a stereo pair at the same time with all changes I apply to the left being applied equally to the right. I need to tweak some of the audio, take out background noise, adjust levels, etc. and my stereo pairs will only import into STP as two separate tracks. When I try to make changes to one track and then apply the same settings to the 2nd track it's too much and the audio sounds like crap. Not to mention it's twice as much work.
    How can I get STP to make the audio I've imported from FCP show up as A1 & A2 (for example) on one track so that I can edit them at once and hear how the effect sounds when applied to both? It's just dialogue so I don't need stereo separation. The doorbell sound effect I'm using from STP shows as A5 & A6 in STP and in FCP it looks just like the other audio tracks (a linked stereo pair).
    Background;
    Some of the audio was recorded on one camera using a boom mic going into input one on the camera. So it was mono and I copied and pasted it to track 2 in FCP and linked it to make it a stereo pair.
    The remaining audio was recorded on another camera using the on-camera stereo mic so it came into FCP as a stereo pair from the start.
    Any help would be greatly appreciated.

    I have Soundtrack and was wondering much the same thing. From your discussion it appeared that one could not split a stereo track into the two mono tracks and then work on each separately. However, upon reading the Help manual for Soundtrack 1.5 at page 167, it explains how one may export a stereo track as two mono tracks as follows:
    To export individual tracks, busses, or outputs:
    1 In the Timeline, select the tracks, busses, or outputs you want to export, then choose
    File > Export > Export Selected [item].
    The [item] shown in the menu changes depending on whether tracks, busses, or
    outputs are selected.
    If nothing is selected, each unmuted track, bus, and output in the project is exported as
    an individual AIFF file.
    2 In the Export dialog, choose the sample rate for the exported files from the Sample
    Rate pop-up menu.
    3 Choose the bit depth for the exported files from the Bit Depth pop-up menu.
    4 Optionally, select the “Output dual mono files” checkbox to export the selected tracks,
    busses, and outputs as dual mono files, then click Save.
    5 Browse to the location where you want to save the exported files.
    6 Click Export.
    Each selected track, bus, or output is exported as a single stereo AIFF file or as a pair of
    dual mono AIFF files. Muted and unselected tracks, busses, or outputs are not exported.
    This might solve your problem because you can then import those two tracks back into soundtrack and work on them separately.
    It worked for me.

  • How do I bounce two mono split stereo files to one mp3?

    Might sound like a stupid question, but I have several problems:
    I bounced a waveburner-mix of my favorite songs as a split stereo file and inserted the two files in two logic mono audio tracks.
    First problem: Do I have to pan the left audio-track left and the right to the right or do I keep them centered?
    Second problem: The two tracks are louder than the original track. (no matter, if they are panned or centered. Shouldn´t the original have the same volume at my output-channel?
    Third problem: Is it possible to bounce more than 2 GB with Logic 8? The mix is very long and when I want to bounce it, logic tells me that it is too big. Can I bounce larger files with logic 9 under OS 10.6?

    Felix Bartelt wrote:
    Last question remaining: Can I bounce larger files under Logic 9 and OS 10.7. or does L9 also have the 2 GB restriction?
    No and no. The file size restriction is not Logics' restriction, it is a restriction of the file type itself. To be able to bounce longer and/or bigger files, use .caf.
    From the manual:
    +AIFF: The AIFF file format cannot handle audio file recordings larger than 2 GB:+
    ++For 16-bit, 44.1 kHz stereo files, this equals a recording time of about 3 hours and 15 minutes.+
    +For 24-bit, 96 kHz, 5.1 surround files, this equals a recording time of about 20 minutes.+
    +WAVE (BWF): The WAVE file format cannot handle audio file recordings larger than 4 GB:+
    +For 16-bit, 44.1 kHz stereo files, this equals a recording time of about 6 hours and 30 minutes.+
    +For 24-bit, 96 kHz, 5.1 surround files, this equals a recording time of about 40 minutes.+
    +CAF: If the size of your recording exceeds the above limits, choose the CAF (Apple Core Audio Format) file format, which can handle the following recording times:+
    +About 13 hours and 30 minutes at 44.1 kHz+
    +About 6 hours at 96 kHz+
    +About 3 hours at 192 kHz+
    +The bit depth and channel format—mono, stereo, or surround— *do not affect* the maximum recording size of CAF files.+

  • Why are stereo tracks plying back in mono?

    Why are some of my stereo audio tracks playing back in mono with a single channel strip level meter even after I assign it as a stereo track with the two circle icon?

    hi and thanks. The files have two circles where the name is. it's weird b/c I have another stereo track which is a copy of the track that isnt playing corectly that works fine with split level meters showing. I have an output track set to 1 + 2 which shows two split level meteres as well.
    mmmm?

  • Split Stereo Channel Output into Left & Right

    Is there a way to split the output of stereo channel strip (in this case, consisting of an EXS24 sampler, with some samples panned hard left) into two mono channels strips, auxes, or outputs (left and right)? For example, in Pro Tools you can select "Track > Split into Mono" to split a stereo track into two mono tracks, and control each resulting track independently. I'm talking about signal path, not splitting a saved AIFF or sound file. Is there a way to do this within Logic?

    Route the output to a bus, then create two new aux channels and assign their inputs to that bus. At that point, you'll be getting the full stereo output routed to each of your two new channels. To split left and right, click-hold on the mono/stereo button at the bottom of the aux channels, and select "left" on one and "right" on the other.
    That should do it!

  • OMF import-How do others deal with stereo tracks?

    When importing OMF's from Avid or FCP all stereo audio files come in on separate mono tracks (ie all music tracks will appear as two adjacent mono tracks). When track managing, all stereo audio files need to be moved from the mono tracks and placed on to stereo tracks (for inserting of effects, etc.) prior to editing and mixing.
    In another pro audio ap that shall remain nameless, one would simply grab the stereo pair (left and right sides of the audio file) from the adjacent mono tracks and drag them onto a newly created stereo track. This method is extremely fast and is vital when faced with an hour long show (especially when the video editor hands off an OMF to which there is no rhyme or reason which happens more often than not!).
    How is this accomplished in Logic?

    Rohan Stevenson1 wrote:
    aaron, read through this twice before and now about 3 times more. i still don't understand your problem.
    i would have prepared tracks prior to importing in logic, or imported them into some kind of template and shifted them around like that. i would use KCs to accomplish most of this. you only need the LH file to play back a split stereo file in stereo.
    Hi Rohan,
    As a professional post audio mixer, I am given OMF's from either Avid or FCP from the client. I have no control over how the tracks are managed by the video editor prior to my receiving them.
    Even if the video editor has track managed the audio appropriately (VO, production audio, FX and music all placed on their own tracks which rarely happens), the files will still come into a DAW on separate adjacent mono tracks.
    For example, all of the music in an hour long program will come in with the left side of the stereo file on one mono track and the right side of the audio file on another mono track. This is just how OMF's translate from video aps to DAW's. The OMF cannot be tweaked to operate differently. It is what it is. Obviously any stereo elements need to be placed on stereo tracks for eq, compression and volume automation.
    When mixing a show, the first thing that must be done is to 'track manage' all of your elements. Usually VO on one track, production audio split amongst a few tracks, mono and stereo effects on their own tracks and then a couple of stereo tracks for the music.
    So let's say I open an OMF. The first thing that must be done is to go through the show, identify all of the stereo elements (most commonly music tracks and FX), grab them from the mono tracks that they came in on and place them on to newly created stereo tracks. In Pro Tools this is a fairly quick process as you are able to grab two mono files and drag them directly on to a new stereo track right in the arrange page.
    Every time you open a new OMF you are confronted with hundreds of regions that need to be track managed before you can edit and mix. Deadlines are always tight so a fast and efficient method is a must.
    What I am describing is standard practice in a post audio workflow when mixing for television. This is not a pressing issue as the studios I freelance for are all PTHD based. However, I would love to start testing my Logic rig at home to see how it stacks up on big sessions!
    Any help or tips would be appreciated.
    Thanks
