How to Convert MP2 to MP3

MP2 (MPEG-1 Audio Layer II) is the audio codec used in DVD authoring, MPEG-2 video files, and broadcast TV. It's the predecessor to MP3 (MPEG-1 Layer III). Converting MP2 to MP3 makes broadcast and DVD audio playable on any modern device — most consumer software supports MP3 but not MP2.

Free tools for MP2 to MP3

  1. 1

    VLC (free, all platforms)

    Media → Convert/Save (on a Mac: File → Convert / Stream) → add the .mp2 file → Profile: Audio - MP3 → choose where to save → Start.

  2. 2

    Audacity (free)

    Audacity opens MP2 files directly. File → Open, then File → Export Audio → MP3 at 192 kbps or more.

  3. 3

    FFmpeg (command line)

    ffmpeg -i input.mp2 -c:a libmp3lame -b:a 192k output.mp3. To pull MP2 sound out of an MPEG video first: ffmpeg -i input.mpg -vn -c:a copy audio.mp2.

Why convert MP2 to MP3?

MP2 is yesterday's broadcast and DVD audio format; MP3 is everywhere. Converting between them makes legacy audio archives playable in any modern context.

Frequently asked questions

FFmpeg command for MP2 to MP3?
`ffmpeg -i input.mp2 -c:a libmp3lame -b:a 192k output.mp3`. For preserving channel layout (stereo broadcast often is dual-mono): `-ac 2`.
Why does my DVD audio play as MP2?
DVD-Video allows MP2, Dolby Digital (AC-3), DTS and LPCM sound, but not MP3. Blu-ray uses LPCM, Dolby (AC-3, TrueHD) and DTS formats instead.
Will MP3 sound worse than MP2?
At the same bitrate, MP3 is more efficient; as a rough rule, MP2 at 192 kbps and MP3 at 128 kbps sound alike. For maximum compatibility with no quality loss concerns, encode MP3 at 192 kbps from MP2 source.
