Import Multitrack audio into logic

    I have a file that has 8 channels of audio recorded into it. How do I bring this into Logic and get Logic to recognize it. I have imported the file but it looks like I am only getting two channels. Basically, at the end of the day, I want to put each channel onto a separate track.

    What is the source of the file? There should be eight individual audio files which you would just import into Logic one at a time.

    There is one file with 8 channels in it

    Nope. Not likely. There is one file with the session info in it and perhaps a single file with a two track mixdown, but no DAW has a single file with 8 channels of actual audio.

    I'll ask again. What is the source device of your audio?

    Sorry I missed that question. This audio has already been recorded from a firewire mixing board in Final Cut Pro. I assure you that I have a single file of audio with 8 channels of audio. SoundTrack pro for example recognizes it just fine.

    You need to export the audio-the "media files" as Final Cut calls them. Export them to a folder you can find later to import into Logic.

    Of course some of the Alesis mixers only export two tracks of audio too.

    Man, you just can't accept that there are 8 channels in one file. I assure you that there are more than two tracks of audio, 8 to be exact. Additionally, it looks like there is no way to export them all at once to individual files. I have to go through each one separately?

    Get over it.

    I gave you the link you needed and could have found yourself in the Final Cut manual. In proper "pro" DAW's and proper "pro" video editors the files are all discreet and easily found. No need to export at all. As an adendum, make sure you export to AIFF or BWAV or Flac so that Logic will read it.

    Also, I must get about a dozen questions a month on Alesis Multimix units and in fact most of them do not export individual tracks but a 2-bus mixdown. This compounded by the fact that you said you only had two tracks of audio - surprisingly erroneous I guess - led me to believe that perhaps you were a bit confused.

    I understand this but it does not look like it actually splits the channels up. Interesting guess with the Alesis - Mackie and Preosnus make similar mixers. You are correct that many Alesis units do behave the way you mentioned but I spent the extra bucks to avoid that.

    Try this stuff and see if it helps you.

    So, import your multichannel file into SoundTrack pro, then export as multiple single channel files. Or am I missing something?

    Failing that Reaper could convert them for you (the demo version would do).

    Sure there is, it's the Apple specific .caf (core audio format)

    Originally designed as 64bit container for multiple surround format mixes.
    Core Audio Format - Wikipedia, the free encyclopedia

    Not at my mac now, but do a get info/ view package contents to get to the individual audio files.

    Not really sure how Logic imports them, try an import from the file menu vs the audio bin.

    .caf can certainly be used by Logic, all of the new Logic content is in that format.

    Also try importing into a surround session.

    Search importing pre-recorded media in the online help for details.

    :cool:

    Multi-channel wavs are also possible... what format is the file in question?
     
  14. TheJackAttack

    TheJackAttack Distinguished Member

    The file is from an Apple specific program, Final Cut, so is likely the format GDub spoke of.

    It is a multichannel .mov file

    Hey Huntson,

    could you post a screenshot of the logic session?

    Now I have a bunch of stereo pairs but most of my sources are mono that need to be panned a certain way or another. I don't need to make a track mono (which I know how to do), but I actually have to say to Logic to only look at one of the stereo audio tracks in the file in each channel of the project. How does one go about that?

    Pan the track hard left or hard right and bounce it to a new track.

    Won't this take everything and pan it left and right - this is obviously not what I want if it does this. If all it does is just output whatever is on the left channel then I am good to go.

    You'll need to really read the manual. I don't own Logic or a Mac. In many of my DAWs and specifically Audition, I can select a stereo file in edit view and then select left or right side individually. I then simply "save as" and voila, a new track. I would imagine in Logic you can select an individual track in some way. If it is panned hard one way or the other and you bounce just that one track then you have split the stereo track effectively.

    Manuals are awesome. I've been working with some manuals for a decade or better and still learn something when I'm digging into them. Often, I print a hard copy to leaf through and I've been at this for 16 years now.
