Output Format
What is MP3?
MP3 (MPEG-1/2 Audio Layer III) is a lossy audio format designed to shrink file sizes while keeping good sound quality. The .mp3 extension is the most widely supported audio format for streaming, downloads, and portable devices.
History
MP3 was standardized in the early 1990s by the MPEG group and quickly became the default format for digital music distribution.
How it works
MP3 uses psychoacoustic compression to remove sounds that are less audible to the human ear. Bitrate and encoder quality determine the final balance between size and fidelity.
How to open MP3 files
MP3 files play on nearly every platform and device. Common options include:
- VLC Media Player
- Windows Media Player
- Apple Music or iTunes
- Foobar2000
- Winamp
- Audacity
- Most smartphones and tablets
Tips for working with MP3 files

- Use 192-320 kbps for music when possible
- Avoid re-encoding MP3 multiple times to prevent quality loss
- Add ID3 tags for artist, album, and cover art
- Convert from lossless sources for the cleanest output
