It re-encodes a AAC audio file as AMR. Sample rate and channel count are preserved; the difference is the codec and container.

Menene fayil AMR?

A bare run of encoded audio frames with no container wrapped around them. That's why two AMR files can usually be joined by simply putting one after the other, and equally why everything beyond the audio itself - a length, a search index, cover art - has to be bolted on as a convention rather than being part of the format, so a player often has to read the entire file to work out how long it is. It's about the simplest thing that can be called a audio file, which is exactly why it pops up inside other containers more often than on its own. AMR shi ne narrowband magana codec aiki tsakanin 4.75 da 12.2 kbps, modeling da mutum vocal tract a matsayin mai cikakken audio spectrum.
