The process requires some manual work at the beginning as the program will only accept wav audio files for input. This means that the user either needs to have a wav file of the future ringtone or convert an audio file into wav format before the creation can commence.

The user needs to add the paths to the Nero AAC Encoder executable and the iTunes library to the portable program upon startup. The program will then check the locations and if they are valid open a file browser to select a wav audio file from the computer system. That wav file will then automatically be converted into the m4r ringtone format. It is then copied to the iTunes library and the ringtone folder of that library.

The process is fine for users who want to created iPhone ringtones every now and then. It could be made more user friendly by adding support for mp3 files and the creation of multiple ringtones at once. It is – as of now – only possible to select one wav file at a time. Not very handy for users who want to create several ringtones for their iPhone. The portable software iRingtones is available for download at the Codeplex website. It is compatible with most versions of the Microsoft Windows operating system and requires the Microsoft .net Framework.
