.mp3ファイルとは？
MP3 is the most recognized audio format in the world, revolutionizing how people consume music since the late 1990s. It uses lossy compression to reduce audio file sizes by up to 90% while maintaining sound quality acceptable to most listeners. At 128kbps, an MP3 file is roughly 1MB per minute of audio. Higher bitrates (256-320kbps) provide near-CD quality. Despite newer formats like AAC and FLAC, MP3 remains universally supported.
