What is MP3 Format?
MP3 stands for MPEG-1 Audio Layer III, a revolutionary audio format that transformed how we store, share, and listen to music. Developed in the late 1980s and standardized in 1991, MP3 became the most popular audio format worldwide.
Understanding MP3
MP3 files use lossy compression to reduce file size while maintaining acceptable audio quality. This compression removes audio data that human ears typically can't hear, making files up to 10 times smaller than uncompressed formats like WAV.
Key Features of MP3
