After making my previous post about Sprint ringtones, I made a ringtone for my fiancÃ©e from a song that she really liked. She had previously said that she was really looking forward to it becoming available and would use it as her ring as soon as it was. She was really appreaciative, but after a couple weeks pointed out that it didn’t sound as good as the other ringtones on her phone. I thought that was weird, because I had listened to that ringtone and some of the ones I had downloaded from Sprint’s site on my phone and they all sounded about the same to me. My fiancÃ©e, being a Sprint employee, has a fancier phone than I do, so I listened to a couple of the other ringtones on her phone, and she was right… the one I made for her just didn’t sound as good. So I went back and did a little more research and discovered that the Sanyo MM 7400 supports MP4 ringtones, provided they have the M4A extention. So, I had to find a way to convert my WAV file into an MP4 file. For that purpose, I used dBpowerAMP. So to make a long story short, she was really happy that I was able to produce a ringtone that sounds just as good as the ones she gets from the Sprint site and was just what she wanted.
