How to cut part of multitrack session to new session in Abode Audition 3.0?

Question

I record live performances in Adobe Audition 3.0's multitrack feature, which are about an hour long.   When I highlight a section of a set of four tracks (containing one of  the songs I want to save out), I cut it, and paste each track into a new session.  However, it  looks like all I'm doing is pasting the *whole* thing, with just a  section showing.
Is there an easy way to create a session in Audition that contains  *just* the portion I'm highlighting?  Having to copy the entire hour  long performance for each song is eating up a lot of storage space.   There must be a way to "trim" the copy so that the raw files associated  with it *only* contain the song I'm looking for...?
I suppose I could find out the beginning/ending times I need, highlight that portion in the first track in track view, trim it, and save it, repeat for all four tracks, and then load them all into a new session, but it seems like there must be an easier way?
Thanks in advance...  Still getting the hang of multi-track recording in Audition!

Answer 1

Sorry to necro this thread, but in case anyone is looking for these sorts of solutions again it may be useful to share my own method(s). I am often faced with this process, and will do the splitting process before I do anything else, this is important for me so I can keep the original files untouched. I am assuming you already have the base multi-track session open and tracks set up. This should work for most version of AA but instructions are based on CS6 (I have CEP, AA3 and CS6 on my machine).
Method A:
1. Select the time the excerpt you want covers.
2. Go to File>Export>Multitrack Mixdown (or right click on the selection and choose Export>Time selection)
3. Select the format you want your tracks to be in - you can leave this as is to use the same as source, or convert to 48k-24bit for DVD or 44k-24bit for CD at this point (the earlier the better). This will be the same as the new session you will create later. Make a new folder for the session audio somewhere and choose that as the destination.
4. Select the Mixdown options [Change] and check each track individually, you can uncheck the master track unless you also want a reference track.
5. Ok all this and wait for export to finish.
6. File>New multitrack session, then create a new session in the folder you created when exporting the audio.
7. Drag and drop the exported tracks to the new session.
8. Finished.
Method B:
1. Create a new session, keeping the original open, make sure the original is the active document.
2. Select the time the excerpt you want covers.
3. Press CTRL-A to select all clips
4. Edit>Copy, flick to new session, Edit>Paste.
5. This creates only the time selections cut out from the ORIGNAL clips, we need to make unique ones, so...
6. You now have, non-unique copies of the whole tracks (the session is referencing the original files), so you need to double click each wave and trim them and make them unique. Once in waveform view, right-click>select current view time then right-click>Copy to new.
7. repeat 6 for each clip, delete the existing clips and drag the new trimmed clips from the files panel tab to the session.
8. finished.
Method A is better for large sessions, but B can be quicker when you just have a couple of tracks and your originals aren't huge.
I'd love a Copy time selection to new session feature that also make new clips...
