Adaptive Multi-Rate Codec File

File extension .amr
File category audio
Description AMR is a compressed file format that functions to enhance speech coding, and it consists of multiple sampling rates narrowband devices used in encoding or decoding. Recording of AMR files can be done using mobile phones. For video and audio files to play simultaneously or accomplish random access memory, one can utilize the 3GPP format. 160 20- millisecond samples embedded in each frame are coded using AMR using ACELP, DTX, VAD, and CNG. Recorded AMR files can be converted into other files allowing their use and for them to be distributed.
Technical details AMR can encode signals ranging from 4.75 to 12.2 kbit/s with quality that begins at 7.4 kbit/s.3GPP took up file format in 1999. It is a method that is utilized by GSM and UMTS. It uses link adaptation to select one of the eight different bit rates. AMR optimizes link adaptation with the best codec devices for it to be used by radio channels and capacity requirements. This only works if the connection is good enough to prevent the loss of audio quality.

MPEG-4 Audio Layer

File extension .m4a
File category audio
Description

Apple Inc. has designed an M4A open-source format based on QuickTime Fike. Now the format is being promoted in the iTunes store. It is a multimedia container intended for the placement of sound components and other data, such as images. MPEG-4 files may be stored with extensions M4A and MP4. In the latter case, they contain video as well.

Alongside these sound formats, MPEG-4 allows for lossy compaction through FFC Codec. However, it is possible to provide a lossless reduction thanks to the Apple Lossless format. The files may be played on Windows PCs via iTunes, Windows Media Player 12, KSP Sound Player, Winamp, and some other programs. With iTunes, the data can be converted into Windows-supported audio formats.

Technical details

In comparison with its predecessor MP3, M4A format provides better sound quality and smaller file size. Thanks to lossless compaction, the data may be easily converted in both directions with no quality deterioration. The sound data encoded with ACC compression, which reduces the file size considerably.

Due to protection technology DRM, MP4 files cannot be easily distributed, while it is much simpler to replicate files in M4A; that is why “Apple Lovers” prefer the latter format. With M4A, it is possible to buy music on iTunes and download it into smartphones or other devices.
