changing pitch of audio without changing tempo

In all honesty Chris - the easiest (and best) solution is to tune your guitar and re-record it.

It also depends how far out it is. For grins, drop it in something like goldwave and adjust it a tad, and see what you think. Still the guys are right it will be a difficult undertaking. My guess is that it will not be possible to move one that little without a problem. melodyne maybe, AcidPro might do it.

Heck by the time you screw around with it for an hour or two you could tune and knock it out.

Melodyne uno is a vocal tweaker, but it can be used for any single note melody. As long as it is not chords, you can easily align a melody or lead line on the guitar, bass, any horn or woodwing type instrument. And the new melodyne has even more ability, I think chords and duets and stuff like that can be tweaked. Unfortunately, uno is a touch expensive, I do not remember exactly, but in the $150 to $200 range, I think.

Ahhhh an old Reo Speedwagon reference.Kinda liked that album.....You can tune a Piano,but you cant tuna fish

You could use Cakewalk's Pitch Shifter if the tuning is not too far out of whack. I'm pretty sure this plug-in is included with MC and you wouldn't have to buy anything. I think this plug-in is under rated by many Cakewalk users. Right click in the FX bin then go to Audio FX > Cakewalk > Pitch Shifter. It's a bit tricky at first because you have to move the cursor out of the Pitch Shift window before it will take affect otherwise it won't work and you'll be wondering what happened. In addition, if you're strumming chords, and only a couple of strings are out of tune, the other strings will be out of tune when you try to correct the intended ones. If all strings are equally out of tune by the same pitch then it should work fairly well as long as you don't try to use an extreme setting on the Pitch Shifter. This should work with both stumming and picking. Make sure the other settings in the plug-in are properly set and I would slide the modulation control all the way to the right for this particular application of the plug-in and 0 Feedback, 0 Delay Time, 100 Wet, and 0 Dry. Also this is only good if you want to change the pitch to the entire track. Using envelopes with this plug-in doesn't seem to work because changing the pitch shift value while the audio is running makes for very unusual sounds in the track.

If you're picking notes and only a few of the notes are out of tune you can edit the audio wav by highlighting the part you want to pitch shift (either one note, a series of notes, or the whole track) then go to Process > Audio FX > Cakewalk > Pitch Shift and then select your pitch. This will cause "destructive editing" but if you don't like it you can undo it immediately after changing it. Editing in this way can be tricky because there's sustain on guitar notes and if you don't get it all it will have pitch jumps. I suggest cloning the track and archiving the original when using this method.

And of course there's always the option of re-recording the track as suggested in the above posts which is good advice unless the person who played the guitar is no longer available.
