Rectify out-of-tune notes (audio guitar recording) ?

[Ally007]

Can anyone share a way to slightly change the pitch of notes in an audio recording?
For example: guitar notes that are slightly sharp or slightly flat.
Maybe the answer is a detuning plugin. Can anyone recommend one (preferably free)?
Thank you!

Melodyne is the best, but it is not free.

The essentials version of Melodyne does come bundled with Waveform Pro, however, as does some version of Autotune.

Some DAWs, such as Cubase and Ableton Live, have their own versions of this functionality integrated into the higher-tier versions of the DAWs. Again not free.

I think you asking about any kind of "PitchShifter" plugins.

Not that I have a solution, but...

Was it recorded with the guitar slightly out of standard tuning, or were there some bad notes hit; and if the latter are they single notes, or a note within a chord ?

It's a fingerstyle piece, with all single notes. Just certain notes are a bit out of tune due to using lighter strings than the player was used to, so some notes are a bit sharp where a fretted string was pressed too hard, or inadvertently bent slightly. Looking forward to your possible solution - thanks!
PS: I think I've found what I need: the pitch control, in clip/track properties!

I use Melodyne all the time, for vocals. An amazing program that I couldn't be without. So easy to use but still astonishingly good results.

I think of it as the software equivalent of alchemy.

That's a clip, rather than a track property. Unfortunately, that will transpose the whole clip; although I suppose you could split it and do sections.

It also looks like it does 1 cent, 10 cents, or 1 semitone, so maybe somewhat limiting?

Graillon is way overkill, but you could pitch-shift exactly (or let it auto-tune for you...).
It can also do harmonies on Guitar or vocals... PS - never used it, but it sounds interesting.

You can definitely cut each note out and change the pitch of each clip segment. As an electronic/in the box guy I do it all the time. You have the steps that Peter mentioned but they are increments, so you can fine tune down to one cent in other words or anything larger. For natural sounding stuff you need to keep it small obviously.

It's the crossfades between your split clips that will sound the last natural if you dont take care. And reverb tails etc.

Also, that's a lot of tedious work! There's easier plugin options I believe.

Yes, changing small sections is exactly what I did. As there are only half a dozen slighty off-pitch notes to correct, it's easy to do.

I think you are talking about the "change pitch" option. Immediately above that, is the "pitch" option, which is what I was referring to. It lets you change pitch in extremely fine increments. Changing the pitch of the off-pitch notes by 0.2 or 0.3 (plus or minus) did the trick for me, in the piece I'm working on.

Yes, I looked at that plugin, recently. It looks like it could be useful. Thanks for your input.

There were only a handful of off-pitch notes that I needed to correct in this case, so changing the pitch of those notes by 0.2 or 0.3 (plus or minus) did the trick. But yes it would be nice to have plugin that automatically corrects all off-pitch notes in a whole track, on one go. Maybe Graillon 2 will work, if the need arises; Yes, I agree about cross-fades. I've disabled that on my setup.
