Edit AMR Apps and Alternatives

AMR is an acronym for Adaptive Multi-Rate and this format is used largely in 3G mobile phones for making brief audio recordings.

AMR format features a built-in ACELP (Algebraic Code Excited Linear Prediction) algorithm which supports efficient human speech compression.

AMR editors will allow users to modify their files so that they can use only their favorite segments as ringtones.
 
Alternatively, they can merge several tracks into a single large tune that can be played on their mobile phone.
