Description🔵

A proprietary format with lossy compression, which have been created as an alternative for MP3 with a higher quality of coding. Overtones out of human perception are being removed. AAC is two times less than MP3, which means 1/10 of CD digital data.

The format has been widely used since 1997 as the seventh release of the MPEG-2 family. As hardware players supply it, the format is highly demanded by music fans. It has been widely spread in Apple production and is being used by default in iTunes.

Technical details🔵

The format conception is similar to MP3, but it is more advanced. Being able to execute larger compression, it is represented as a separate segment of MPEG-4 standard used to create compact audio files. AAC is highly efficient with variable and continuous bitrate, with a sampling frequency of 8-96 kHz.

The current version complies with the standard of ISO/IEC 14496-3. Compression is performed based on an auditory masking effect that provides data reduction with no deterioration for sound quality.

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.
