Chuyển đổi sang MP3

MP3 (MPEG-1 Audio Layer III) is one of the most widely used audio formats in the world. It is designed to significantly reduce file size while maintaining acceptable sound quality, making it ideal for music, podcasts, audiobooks, and online streaming.

Thanks to efficient lossy compression, MP3 allows audio files to be easily stored, shared, and played on virtually any device.

Detailed Description of the MP3 Format

MP3 was created to make digital audio smaller and easier to distribute without requiring large storage space or bandwidth. By using perceptual lossy compression, MP3 removes audio data that is less noticeable to the human ear, achieving a strong balance between file size and sound quality.

This format became the industry standard for digital music distribution and remains widely used today. MP3 files are compatible with almost all media players, operating systems, smart devices, and car audio systems.

Although modern formats like AAC and OGG can provide better quality at lower bitrates, MP3 remains popular due to its universal support, simplicity, and ease of use.

Features of MP3

• Small file size – efficient compression for easy storage
• Wide device compatibility – supported everywhere
• Adjustable bitrate – control quality vs file size
• Metadata support – artist, album, cover art, track info
• Ideal for streaming and downloads
• Lossy format – some audio quality is removed
