MKV to MP3: extract the audio of a movie or a series
The MKV (Matroska) format is widely used for movies and TV shows: it often embeds several audio tracks (original, dubbed, commentary). Extracting to MP3 pulls the main audio track into a light form, playable in a car, on an MP3 player, or in a podcast app.
The default audio track is extracted
If the MKV holds several tracks, the one marked as primary is extracted. To extract a different track, first change its selection in a player like VLC.
Weight divided by 20 or more compared to the MKV
A 2 GB MKV can become an 80–120 MB MP3 at 192 kbps: ideal to listen to a soundtrack or the dialogue of a movie without carrying the full video. Also useful for recorded lectures or webinars.
