Download the youtube then extract the audio (google the method online using a free app. There are a few out there that can do this). Then follow my guide on creating your custom ringtone :}

You may need to trim the audio depending    shouldn't be too hard to do with a free app available via google.
This is a preview of the RCP tone app ringtones

If you want an APK ringtone package, i recommend this one https://play.google.com/store/apps/details?...e=search_result They have the normal ring tones like say in the office ... and a lot of others .... Personally though i use my own custom ringtone and notification. Ringtone: J-E-N-O-V-A For notification i use: Fanfare I converted the audio from my music cd from wav to AAC. I then put them into the following folders on my S3 smartphone. So i created these 2 folders under this directory Notifications Ringtones Then i put jenova into ringtones, and fanfare into notifications. I then go to settings > sound > ringtones and notifications and change them accordingly. I like the new sound but i think fanfare needs to be trimmed/modified to be shorter. Too long a notification is not necessarily a good thing. Here is a video guide how to add your own custom ringtones and notifications I also want to recommend this other app called call end tone. It plays a sound of your choice when the phone is hanged up. This is most over looked. Don't you have that silent end call and left wondering whether the call ended or not on your black screen ? No more second guessing with this app https://play.google.com/store/apps/details?...e=search_result
