I downloaded and installed into Audacity something called Auto Talent. It seems to be an alternative to Auto Tune. Auto Talent is for Linux.
Does anyone know of anything else that would help with a not so perfect pitch voice ?
Thanks for your Time and Effort.
On Linux, the two options that I know of are: “Auto Talent”, and the other is singing lessons 
I sympathize greatly - I can sing a note which is perfectly in tune as I sing it, but the sound that comes out of my mouth somehow magically changes into something completely different. My solution was to learn to play the violin instead.
