Mobile AMR to WAV Converter. If you mess around with mobile phone audio files it’s likely that you’ve come up against the .amr (Adaptive Multi-Rate) format which is used quite a lot at the moment. This small freeware program lets you convert to and from .amr and MP3 and WAV, so you transfer your audio to ringtones and convert your sound recordings to something more usable. It’s one of those tiny utilities that you stick in your bag waiting for a rainy day.
The Mobile AMR converter uses Sony Ericsson AMR converter to convert AMR files (Adaptive Multi-Rate Codec, *.amr) to wave files (*.wav) and vice-versa in a user-friendly way. Also, you can directly convert MP3 to AMR files for use with your mobile. It can also save several wave files into one SP file and vice-versa. The program has a very easy-to-use and simple GUI (Graphical User Interface) that helps even the most amateur user. Most of the times, the only data that you must enter are the input file(s) and the output file.
