AMR is an audio format which is extensively used in mobile devices in various applications ranging from normal audio player/recorder to VoIP kind of applications. AMR can be further categorized as: AMR-NB( NarrowBand ) and AMR-WB( WideBand ).
AMR-WB ensures that speech quality is optimized in a mobile station by verifying its ability to determine when to request a change to another codec with either more or less error correction and protection as signal quality changes. AMR-NB (Adaptive Multi-Rate Narrowband) is a vocoder employed in low-bitrate applications like mobile phones.
AMR is also a file format for storing spoken audio using the AMR codec.
