About pitch less than a half tone

[PaoloS]

Hi folks,
I'm using Audacity 2.1.2 both on Ubuntu Linux (17.04) and Windows 10.
Often I change tune of a music downloaded to make it easy for my student (I teach blues harp in a Music school).
Recently I need to tune a song less than an half tone, because I found the original song is in the right key, but low about 10-15 Hz.
So, I found the right tune after a lot of trials: is there a fast and better method to do this?
Thanks

Were you using the Preview button in the change pitch effect? I generally find that a bit quicker than "apply -> undo -> apply a bit different -> undo ->..."

Yes, sure, but I'm looking for a method to precisely find the real tune... Is there a method or the only way is to proceed for trials?

There's a plug-in here that is pretty good at finding the pitch of a single note: http://wiki.audacityteam.org/wiki/Nyqui ... tch_Detect
Installation instructions are here: http://wiki.audacityteam.org/wiki/Downl ... ns#install

I placed the file in the folder you suggested; save the change; close Audacity, re-open it: the EFFECT list doesn't contain the new plug in.
How can I solve?

You have to click on the Enable button, then the OK button below it, before the effect appears on the effects list ...

Thanks Trebor, but as soon as pressed "Submit" to send my message, I found the solution. Sure, I already enabled the plug in, but it appears in "Analyze" menu and not in "Effect".
Solved!
Thanks again to all
