| Description | 🔵 The .mp format refers to an audio coding format for digital audio that employs a form of lossy data compression. It's a widely used audio format for consumer audio streaming and storage and has become the standard codec for transferring and playing back music on most digital audio players. MP files reduce file size without significantly impacting perceived sound quality by eliminating sounds beyond most people's hearing range. |
| Technical details | 🔵 The `.mp3` format, MPEG-1 Audio Layer III, is a commonly utilized digital audio format. Key technical details include: - Lossy Compression: Reduces file size by removing inaudible sounds. - Compression Ratio: Typically about 10:1, balancing quality and size. - Bitrate: Encodes at variable rates, affecting quality and size. - Sampling Rates: Supports a variety of rates, including CD quality. - Channel Modes: Provides options for mono, stereo, joint stereo, and dual channel. - Metadata: Contains information such as title, artist, and genre (ID3 tags). - Streaming: Ideally suited 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 (the range of human hearing). - File Size: Significantly smaller than uncompressed audio. - Psychoacoustic Model: Removes less audible frequencies. - Developed by the Fraunhofer Society in the 1990s, the MP3 format revolutionized the music industry with its efficient compression and broad compatibility, simplifying digital audio storage and sharing. |

| Description | 🔵 AMR is a compressed file format that is designed to improve speech coding and includes multiple sampling rates for narrowband devices used in encoding or decoding. AMR files can be recorded using mobile phones. To play video and audio files simultaneously or achieve random access memory, one can use the 3GPP format. Each frame contains 160 20-millisecond samples that are encoded using AMR with ACELP, DTX, VAD, and CNG. Recorded AMR files can be converted to other formats for distribution and use. |
| Technical details | 🔵 AMR is capable of encoding signals in the range of 4.75 to 12.2 kbit/s, with quality starting at 7.4 kbit/s. 3GPP adopted this file format in 1999, which is used by GSM and UMTS. It employs link adaptation to choose from eight different bit rates. AMR optimizes link adaptation by selecting the best codec devices for use on radio channels and capacity requirements. However, this optimization only works if the connection is strong enough to prevent any loss of audio quality. |
