Do you happen to know of any tools for fixing pitch issues in music files?

I used Audacity recently to fix some youtuber's backing track for guitar improv, by tuning down 7 cents. I reuploaded it: https://www.youtube.com/watch?v=TE3pgOkfYu0 https://www.youtube.com/watch?v=TE3pgOkfYu0 In that case, it's a pure stretch: i.e. the tempo is slowed down by a factor of 0.996 to achieve the pitch change. I also have an unpublished version of that track transposed from the key of Em to Dm; that was a pitch change preserving tempo.

  How did you determine 7 cents was the correct amount?

    Trial and error. Guitar meticulously tuned to concert pitch, with attention to the 12-15 fret area, then compare against versions of the track slowed down by all available factors in audacity from around 0.993 to 0.998. (The stretch tool doesn't take more digits, stupidly.)

      "Guitar meticulously tuned to concert pitch, with attention to the 12-15 fret area" When you need to pay attention to anything outside of open string, fretted 12th, open harmonic 12th fret (and fretted 24th if you have a 24+ fret guitar) for intonation, it's time to get the guitar to a luthier for setup maintenance. Something else is drastically wrong in the setup.

        When you're deciding between a 6, 7 and 8 cent pitch shift, using your instrument as a reference, you should pay attention to the notes you are using, no matter how confident you are in the intonation.

Depends on what you're trying to do. For guitar practice, I use AnyTune Pro+. I use for learning the lead, because with my musical experience I can nail the rhythm guitar part by ear in a couple minutes. Not so with lead guitar parts, I'm afraid! But yeah, you can adjust frequency, you can adjust playback speed, you can pick a point A and a point B and loop between those points (great for breaking down each section of the solo). If you slow the playback speed slower than 70% or so, you're going to start getting a lot of digital noise. Once you've learned how to hear the notes through the noise then you can learn even super fast solos. As I'm writing this I'm thinking to myself I know there are AI tools now that can take any track and produce all the stems for all the different parts in the track. You'd think for something like the lead guitar they could analyze that stem and produce either the tablature or standard music notation for the solo. That would be kinda awesome! I wonder if such a tool now exists?

  I wrote elsewhere that I recently asked Claude AI to help me learn a Pixies song on guitar and it wouldn't give me anything but generic advice because of copyright.
