Converting MKV to MP3: what to know
MKV is the container used for movies, TV series and concert recordings. Converting it to MP3 keeps the soundtrack, a song or the dialogue so you can listen without the video.
Only the audio track is kept and the video is dropped, so the file becomes many times smaller. You can save just a fragment by setting the start and end on the timeline. A movie's surround sound is mixed down to stereo in MP3: the format holds at most two channels.
