    Any way to duplicate a track and designate a channel to it?

    VidNoob Community Member

      My issuse is that I have audio with 2 channels that i import into Audition and they all need noise reduction. I need to take out multiple low frequency band hums, and cant nail them with any filters so I need to do the clips oen by one with the noise reduction. What i would LIKE to do, and was wondering if there's a way to do it, is just delete the one track I didnt do the NR on so i don't have to apply the noise reduciton to all the other separate clips, and just instead duplicate the one track that I did all the noise reduction in and, set it to either be left or right channel?

          Well if it's a stereo file to start with, there's a Edit menu item to 'Extract Channels to Separate Files' which will do this for you.

            You could what you want (delete the "unchanged" track and copy the "changed" track in its place) but if your original audio is a stereo track you are going to lose one half of the stereo signal.  If the two tracks are both mono and both contain exactly the same audio, then go ahead as you propose.  If you then set this remaining track to "mono" it will be exported equally to both left and right.

             

            For future reference, if you have similar problems with this type of multi-frequency noise, which demands a multi-pass approach in Audition, you might consider investing (some serious bucks) in iZotope RX2.  It is capable of removing "multiple low frequency band hums" in far fewer passes, perhaps as few as one!
