pulling just the audio out of a video on windows 10

VLC can do it if you have it. Media > Convert / Save, add the video, click Convert / Save, pick the Audio - MP3 profile, choose where to save, Start. It plays through silently while it converts, that's normal. If you're ok with a command line, ffmpeg is faster and doesn't re-encode: ffmpeg -i video.mp4 -vn -c:a copy audio.m4a That copies the audio track out as it is, so no quality loss.
