用於數字音頻的開放標準有損壓縮格式
MP3 is a compressed audio format developed in Germany that dramatically reduces the file size of digital sound recordings—typically by 75–95% compared to CD-quality audio—while maintaining sound quality that most listeners perceive as faithful to the original. This efficient compression made MP3 files practical for storing and sharing music digitally, which is why the format became widely used for personal music collections and online distribution.

动态图像专家组-1或动态图像专家组-2 音频层III（英語：MPEG-1 or MPEG-2 Audio Layer III），常简称为MP3，是当今流行的一种数字音频编码和有损压缩格式，它被设计来大幅降低音频数据量，通过舍弃PCM音訊資料中對人類聽覺不重要的部分，達成壓縮成較小檔案的目的。而对于大多数用户的聽覺感受来说，MP3的音质与最初的不压缩音频相比没有明显的下降。它是在1991年，由位于德国埃爾朗根的研究組織弗劳恩霍夫协会的一组工程师发明和标准化的。MP3的普及，曾對音樂產業造成衝擊與影響。
