Autotune

Autoton is a simple tool that allows you to easily arrange different friend requests with similar frequencies: dragging and dropping.

In this way, all you have to do is select the note that you want to use as a base and drag all the sound files you like. In a few seconds you will be ready.

The only problem with this simple method is that if you want to listen to its original version so that the file will be converted permanently, it will be better to create a security copy.

Ototon is a very powerful tool because it combines songs with ease and speed, though its options can be a little basic.
