slowing down an audio track

I know this is something to do with groove clips but I'm quite nervous that I might mess it up.
My song was at 95bpm but I have decided it is better at 92bpm. The trouble is, I am not certain what to 
do to the audio which is recorded at 95bpm to get it to 92bpm. This does not involve looping. I just want
to slow down the vocal track to match 92 bpm. Could someone give me a step by step explanation of what
to do?
Thanks
Echo

    First, back up your work by either 'Saving the project As' adding 'slow down vox' to the file name OR simply clone the vox track and Archive and Hide one of them. Stuff happens and it's a good way to preserve your work thus far.

    Second, if you haven't already done so, highlight all of the Vocal and bounce it in place, making sure you slip the front all the way to zero before the bounce. Once you have a single vocal clip that starts at zero you can move to the next step.

    Third, set your tempo back to the original tempo of 95.

    Fourth, select the vocal clip. Go to Views, Audio sanp pallete and toggle 'clip follows project to ON. You'll see a two ended red arrow on the top left hand of the clip now. Next, Click on the little tab just to the right of the words Clip follows project. (when hovering above it'll say 'Resolution for Clip following project) Make sure it's set to Auto stretch! Now look in the same Audio pallete at the options for render mode Offline and here you can set it to either Radius mix or Radius Solo (vocal)... vocal setting USUALLY works good on a vox, but if it doesn't Radius mix will work great. Radius mix works great on polyphonic material for stretching. ocaisionally I have an issue with the Radius Solo (vocal) so that's a just in case.

    Fifth, Change the tempo to the desired tempo of 92.

    Sixth, right click the clip and bounce to clip.

    You will now have a vocal that is in the correct tempo for the song. Hope that helps!!

    wow, I came on here looking for some help with this same thing.  i have googled the heck out of it and really couldn't come up with an answer.  i did see that you could hold shift and control with cursor at end of clip and stretch that way, but even with just a 1% change the result was unusable.  Sure wish it was as easy as that. It may be that when you bounce to clip and render it it offline, (i guess that is what it is) that the results are better , but I don't see how to change what type of time stretching is applied (radius etc).  maybe it is not an issue.
     
    I have a solo piano track that I am editing together from different takes, which have slightly different tempos.  It looks like this method above should work, yes? Except that the takes were just recorded freely and the tempo in Sonar are all 120.. although the actual tempo of the playing in the takes are different. So I'm not sure
     
    Any help is sincerely appreciated... on a bit of a deadline.

    Maze- Bouncing down the Cntrl Shift clip (bounce to clip) will use the offline algorithm. What you are hearing is the real time render that sounds bad. To change the Offline render mode, select the clip or clips you want to change the mode on, select Views, Audio snap pallete, Where it says Offline render mode, select Radius mix. Now stretch and bounce as necessary.

    Yeah, even just 1% time stretch with SHIFT/CTRL  then bouncing to clip, although much improved is still not usable... giving a slightly muffled sound.

    I too am about to try this (but to speed up a track).  This is very helpful.  I will prob. end up re-recording, but I want to do a 'test' to see if the fast BPM is what I am looking for.  Thx!

    Thank you Blogospherianman, you are of course absolutely correct... and that was a huge help to me.
