Balancing out audio levels

Okay I recorded a four hour show on a Tascam dr-40. The board mix is a little hotter on the left that it is on the right. The entire first half of the show, it was split between two different files drops in volume approximately halfway through.
Can I find the average RMS and adjust from there?
Before I start sweetening it up I would like everything to be just about the same volume from beginning to end and left and right. Is there a quick and easy plug-in that will do that? I also own sound Forge Pro.

Thank you all.

    Do you have a stereo file? Open it in Sound Forge. Look at the wave forms to see which one is high and which one is low. Double-click on the low one to select it (one channel only), then click Process|Volume... and raise it an amount that feels right. Play it back and see if you got it right. If not, Ctrl-Z to undo and try again until the channels match.
     
    Note: If the channel that's louder is too loud and is clipping, do this same process on that channel instead, lowering it until it matches. Of course, if it's clipping there will still be distortion, but at least the levels will match.

    You could also try the Channel Tools plugin for this - just adjust the L.Gain and/or R.Gain until the levels match (the "out" meter should also give a visual indication).

    I'd address this with manual automation rather than a plugin. That'll get you better results in the end.
     
    SONAR's pan control is in fact a balance control, and therefore provides exactly what you need. You just need to insert a pan automation envelope. You might, however, need a little volume automation as well, in case the overall volume changes as you adjust the L/R balance.


    All else is in doubt, so this is the truth I cling to.

    This was a live show taking a feed off the board. Likely the disparity between channels is the same all the way through. Anyway, that seems to be what Westside Steve said in his post. So I don't think he'll need to automate anything. Just reset the balance one time. Not that Steve's reading any of this, but if he is, now he's got a few ways to go.

    Ha. Yes sir I have read all of these and I do have a lot of ways to go.
    I eventually clicked on the one track and went to process volume and added a few DBs at a time.
    I think all those ways would work. Had I not read the sunforged first I'd probably have used the pan control which seems pretty damned logical.

    I've just been away from the studio for a few days sorry if I was rude.

    Which brings me to another question! Another volume based question. Two files one from Friday night and one from Saturday night both well over 3 hours long and has been split into 2 parts on the Tascam dr-40. I have them all balanced out but I want to make sure that part 1 and part 2 are the same volume. It's a little bit harder to do that visually. Without squashing things too badly is there a limiter setting I could use that would set everything at possibly minus 6 without clipping or flattening things out?

    Sincere thanks fellows.

    PSY Larry yes it's a stereo file but not actual stereo, I think it's maybe just dual mono but there is a left and right.

    After the volumes are as close as I can get I will put a light limiter on it exterior wide setting a final compression from sign for it mastering stuff and a little bit of mastering Reverb.

    I used to have audio track mixed in with one of the two camera mics in Vegas Pro.

    In sonar I take the processed board mix and the camera mix and feed the crowd noise in and out.

    If the DR-40 split the file, it's because it has a file size limit. There's no reason I can think of why the two parts would have been recorded at different levels. If for some reason the levels between the parts actually are  different, I'm still thinking you could do this most effectively and safely using the "Volume" command in Sound Forge. Put parts 1 and 2 back to back in SF, visually squeeze the display down to where you can see the whole thing from beginning to end. Now you have your ears and your eyes on the job, you can adjust the volume on one part or the other so they match.
     
    If you really don't like this method you can try the "Normalize" command in Sound Forge. This is destructive, so either save a copy of both parts before you start, or be ready to undo right away if you don't like the results.

    Hi, you are correct there shouldn't be any difference so maybe I did something funny and didn't notice it. I still have the original tracks on the chip so it shouldn't be too hard just to start over and make sure I'm increasing the volume my equal numbers. Thanks.
