depending on the model phone you have (but almost all Android phones) you would need to download a program that will "convert" (but it really doesn't convert per se) the sound into a format that your phone will recognize as a ringtone, notification tone or an alert tone. From the Google Play store download a program called Ringtone Remix. That's the program that I've been using the past few years to make and alter other media for ringtones on my Android phones.I've tried installing the ringtones to my computer and my phone. On the computer, they show up fine ... they play as mp3, they're right there. I've also tried downloading them straight to my phone; as far as I know, they're on there, I just can't find them and set them as ringtones. Please help!
