To create your own ringtones based on your favorite songs nothing better than a thought and dedicated program exclusively to it as it is Free Ringtone Maker. There are other options to do it without having to use any third-party application such as using Garageband and exporting it to iTunes, but in my opinion, this dedicated program makes everything easier.
Your entire iTunes library in one click
Its operation is as simple as running the program showing you from the beginning your entire itunes library, so without configuring anything you can now click on any song to adjust the duration of the tone to your liking and create it as you see fit. You can even drag and drop the song you want to transform it without necessarily having to be in your library.
Free ringtone maker can be downloaded from the Mac App Store for free and perhaps because of that it has some bugs that still need to be improved, bugs such as not finishing loading a song to start editing it, showing us the loading circle continuously going around without ever ending up in a loop, although not This means that the application has crashed since we can go back to the beginning, but it simply seems that it does not load some songs. Another negative aspect is integrated advertising in the corner but in the background, it does not bother when using the program.
But not everything is bad and we can also change the sound quality in the application preferences to achieve a "higher quality" tone. In conclusion, it is a recommended program to carry out the process of bringing all the music you want as a tone in very few steps and with quite a few customization options, although as I have already said they still have a couple of details to be polished.
