I'm using a program called "Ringtone Maker". Simple, easy to use, does what I need. It's in the Play Store.
When my wife's Maxx updated to kitkat last weekend all her custom ringtones turned into gongs. When I went into the ringtone selection for her phone I found 2 copies of each custom ringtone. One had the gong sound and one had the original sound. Weird but all I needed to do was choose the right one and problem solved.
