Description🔵 .mp (MPEG Layer Audio) The .mp format is an audio coding format for digital audio which uses a form of lossy data compression. It is a common audio format for consumer audio streaming or storage, as well as a standard de facto codec for the transfer and playback of music on most digital audio players. MP files compress audio data by eliminating sounds that are outside the hearing range of most people, thus reducing the file size without significantly affecting the perceived sound quality.
Technical details🔵 The `.mp3` format, MPEG-1 Audio Layer III, is a popular digital audio format. Here are the key technical details: - Lossy Compression: Reduces file size by removing less audible sounds. - Compression Ratio: Typically around 10:1, balancing quality and size. - Bitrate: Encoded at different rates, affecting quality and size. - Sampling Rates: Supports various rates, including CD quality. - Channel Modes: Offers mono, stereo, joint stereo, and dual channel. - Metadata: Stores info like title, artist, and genre (ID3 tags). - Streaming: Suitable for internet audio streaming. - Universal Playback: Compatible with most devices and software. - Variable Bitrate (VBR): Dynamically adjusts bitrate for efficiency. - Frequency Range: Covers 20 Hz to 20 kHz (human hearing range). - File Size: Much smaller than uncompressed audio. - Psychoacoustic Model: Removes less audible frequencies. - Developed by Fraunhofer Society in the 1990s. MP3 revolutionized the music industry for its efficient compression and wide compatibility, enabling digital audio storage and sharing.

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.
