How to quickly export audio from video?

Question

Video processing

Good afternoon, please tell me a video editor for quickly exporting a part of an audio track from a video to a file. It is desirable free, at least for acquaintance.
I have purchased Movavi Video Editor - but this program only supports one track and doesn't know how to save the audio selection. Here:

Answer 1

ffmpeg , of course. On the command line or terminal under Windows, Mac OS, Linux.
In any player (for example, VLC ), determine the start time of the desired fragment, its duration and the following command:

ffmpeg -ss 16:27.600 -i movie.mp4 -t 5:55  audio.wav

This will "rewind" to 16 minutes 27 seconds and from there, will only output the sound 5 minutes 55 seconds long. to the audio.wav file
If there are several audio tracks in the video, you must select one of them. To do this, first display information about the file:
And then select the desired audio stream using the parameter -map:

ffmpeg -ss 16:27.600 -i movie.mp4 -map 2:a -t 5:55  audio.wav
