I'm trying to make some custom ringtones for my iPhone 4 just to change things up a little. I've found some guides on how to do it only using iTunes. The only problem is that, unlike the majority of kids who want their favourite 'Akon' song to blast out when someone calls them on the bus, I can't think of anything more annoying than hearing a song every time someone calls. So I'm trying to use sound FX and famous sounds from film/TV/video games etc, but that's where I'm running into problems... Most of the sounds I have are in .wav or .mp3 format, so I convert them to AAC and then change the file-extension from '.m4a' to '.m4r', but when clicked they just open in iTunes, they don't get placed into the 'ringtones' section. None of them are more than 30 seconds long, so I thought maybe that was the problem. So, I looped the files for 30 seconds in Audacity and exported to MP3, then imported to iTunes, then converted to AAC, then changed the extension to .m4r (PHEW! this is becoming harder than i'd like....come on, Apple!) but still it didn't seem to show up under 'ringtones'. I also spotted a simple program that does all the hard work for you, but it was Windows-only.... Any ideas where I might be going wrong?
