M4A

MPEG-4 Audio Layer

The M4A file format forms part of the MP4 specification, specifically the audio stream of the Mp4 format. .m4a files are essentially audio only bit streams encoded using the audio codecs from the MPEG-4 Part 14 specification. Audio encoding can be accomplished using algorithms from the lossy family or lossless family of codecs. One of the design goals of the M4A audio format was to achieve a high level compression ratio without sacrificing audio quality. In this regard, it was intended that the format would succeed the MP3 file format. Although it has done this from a technical standpoint, the MP3 format continues to be widely used.
AMR

Adaptive Multi-Rate Codec File

The .amr filename extension refers to the adaptive multi-rate audio codec initially released in 1999. The format is typically used to encode speech audio and is optimized for this purpose. It can encode speech into one of two file version, either AMR-NB (narrow Band) or AMR-WB (Wide Band) which supports a broader frequency. Because of its optimization for speech audio, the format has been widely adopted as the standard speech codec for GSM and UMTS mobile phone networks by the 3rd Generation Partnership Project ' a collaborative group of organizations in the telecommunications industry.
