Finding and setting project tempo of songs recorded without a metronome to fix drift?

Hello, all. I'm not sure if X2 Producer has this function but I figure with all the other doodads it just might. Failing that perhaps some of you smart fellows have some creative workarounds.

So here's the deal... I've got a series of about 20 tracks of my old band (multiple takes of 9-10 songs). I finally got them off my old system and painstakingly inserted them track by track into X2 (only way it would work the way I wanted). I'm very happy with this. Now what I would like to do is some correction on the drums with Audiosnap and eventually the rest of the parts with some light time stretching. These were NOT recorded to a metronome or any kind of fixed tempo. It was just us doing our thing live in studio. Soooo...

Is there a way to have Sonar take a look at the songs and guesstimate the tempo? I would use the snare track for reference and even do it section by section for any severe drift or intentional timing fluctuations. I find the tap tempo thing just doesn't work (fluctuates WILDLY) so that's out unless maybe I'm using it wrong.

If I could just get the closest tempo match possible I intend to use audio snap to correct the drift and any wayward drum hits. I know this is a tall order and could take a veeery long time but it's worth it to me as this album should have been released ages ago.

tl;dr... How can I take a snare track to approximate a song's tempo for audio snap editing?


Thanks, guys and I hope you all have a great day.

    Hallo, Beepster, it's nice to see you on here a bit now.
     
    I don't know if it would help, but FastBikerBoy did a video on youtube doing something similar in X1 - it might be worth a look.
     
    Hope all is well with you.

    Hi, jb. Thanks. I hope life's treating you well too. I did a massive study session on all the Groove3 stuff and then spent a couple months working on theory so I didn't have much Sonar stuff to talk about. I'll take a look for that vid. Any keywords that might help me dig it up? Cheers.

    I think I found them... watching now. Thanks, jb... and Karl wherever you are. ;-)

    Okay, so this isn't exactly what I was envisioning but I'm pretty sure with this method I can get to where I want. I'll link the vids in case anyone searches for this topic.

    This is the first vid Karl did which I guess is the "hard" way but it helps with understanding what's going on and why.

    Here's the followup vid he made after Cory gave him some extra insight on the process.

    Awesome. Thanks again.

    Alright I think I understand this part now so I have a follow up question. Once I create a tempo map based on the original recording how can I make it so that all the drum transients (all tracks) snap to a steady tempo? Example: I enable audio snap on all the drum tracks so I can move the transients in relation to each other (like in the Drum Production webinar). Now I would want to change the tempo map to one even tempo instead of many different tempos and have all those transients snap into place automatically. Can this be done or will I have to do it manually?
