Can I change the pitch using VLC?

I know VLC can slow down / accelerate audio without changing the pitch. What I would like to do is the opposite, change the pitch (hopefully by units of semitones) and keep the tempo. Can it be done with VLC?

Or at least, can i change the pitch, even if the tempo gets changed as well?

Yes, VLC can do this. Go to:

Tools -> "Effects and Filters" -> Audio -> Advanced

It can adjust the pitch (without changing tempo) up to one octave (12 semitones) up or down. It indicates fractional semitones as x.0 x.3 x.5 x.8 . (I don't know if these are actually steps of quarters of semitones (ie eighth-tones) or "continuous" or what.)

I know that this feature works on vlc 3.0.4 (Linux), but I have no idea when the feature was introduced.

(BTW, this seems to be essentially the same as this question)

Edit: On further digging, I see that on Windows (at least with VLC 3.0.7.1), it works exactly as described above, except that you may have to widen the "Effects" window or click on the right-arrow to display the "Advanced" tab.)

On Mac OSX, I found the "Audio Effects" menu (View -> "Show Audio Effects Button", then click button on lower right) Unfortunately, I could not find the "Adjust Pitch" effect, nor even an "Advanced" tab.

I am not sure how if this is possible with VLC but you can easily do it using the free Audacity program. Once you open a file using Audacity you can go to "Effects->Change Pitch"

You can also do it on Mac, but it requires a restart of VLC:

1. Preferences > Interface > Show All
2. Audio > Filters > check Pitch Shifter
3. Audio > Filters > Audio Pitch Shifter > set Pitch Shift amount
4. restart VLC

Anytime you want to adjust the amount of Pitch Shift, you will have to restart VLC again.
