You may be having the swankiest cell phone on the planet – but that MMS you are sending to your friend – he may not be equally blessed. You send him a ring tone in .wav format or .mp3 format, while he may be having support for only AMR. So what do we do?
We download a nice little utility from Miksoft called Mobile AMR Converter. As the name suggests, this program converts .mp3 and .wav into AMR, and presently has support to convert .wav back to AMR. The software can also save several SP files into one. The program is strikingly easy to use and a novice gets accustomed to it very easily – after all, there are not many options to meddle with. AMR is the format of choice while MMSing, as it ensures compatibility; and here we have a program which does the job of conversion from the ubiquitous MP3 and WAV to AMR.
