| 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. |
