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.

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.
