Can I speed up a stereo audio track by a few bpm's?

I need to increase the tempo on a stereo WAV file by a few beats per minute. The current tempo is 100. Is there a way to do this? If not, is there another program I can get that would achieve this?
 
I've done a search on this subject but only found a few threads dating back to previous versions of Sonar that don't offer anything I can use. I read through the recent thread on synconizing audio with midi, but that's not what I need to do. I tried a few of the suggestions anyway, with no useful results. It seems like it would be a simple procedure, but maybe not. 
 
I'm working in Sonar X2 Producer with Windows 7 on a Sweetwater Creation Station. I have the Scott Garrigus book Sonar XI Power, but haven't found what I'm looking for in there. It might be there, but I haven't found it. Sometimes I don't know what the function I'm looking for is called.
 
Thanks in advance for any help.

    Select the clip and press "A" on your QWERTY keyboard.
    Then select "Clip follows Project"

    Ctrl+drag the end of the clip backward - that will time-compress it by whatever amount you choose.  A percentage should display in the clip header.

    Beware of the fact that you can end up with artifacts in the music. I would imagine you have a safety back up before you do any heavy rendering. 
    My experience with trying this with audio has always ending up with a compromised sounding track. If it is just a drum loop you might be OK. But a full mix might become wonky. Listen carefully and be ready to hit undo.

    After using Ctrl+drag to change the tempo. You will then need to 'bounce to clips' This will get rid of the artifacts and typical glitches.

    Just that 1: This process is destructive....so work with a copy of the original.
                  2: You cannot go to far from the original tempo without sounding too strange anyways.

    Thanks for the relpies. I tried the suggestions and was able to speed up the track, however it did leave artifacts. I haven't tried simpleman's suggestion to bounce to clips yet, but I'm hopeful that it will remedy the artifact problem. I was almost resigned to recutting all the audio tracks, but hopefully the bounce to clips step will do the trick. I'll try it tomorrow when I have time. 
     
    I learned long ago to make backup copies of everything before trying anything I'm unsure of. I learned the hard way, so I appreciate the advice from those who gave it.
     
    There sure is a learning curve on X2. I was using Sonar 8 until a few weeks ago. I'm still hunting for things and figuring out the logic of the changes. I think I'll like X2 when I get more familiar with it. It's a bit frustrating so far.
     
    Thanks again for the replies.
