Can iTunes, QuickTime Player or any free software be used to convert a bunch of MP4's to MP3's? I have 184 video lectures I gave I want to turn into MP3's. So far QuickTime Player worked great, but that only converts one at a time and it is a very tedious and repetitive work.

I combined what you helped with and the StackOverflow and came up with the solution below. I created a fold on the desktop, moved all the videos in that folder. I created the folder "outputs" within the folder with the videos. I option-dragged ffmpeg from the bin file to the folder with the videos (NOT in outputs). I wrote in terminal:
cd Desktop
cd "The name of the folder with the videos I wanted to convert"
for f in ./*.mp4; do ./ffmpeg -i "$f" -c:a libmp3lame "outputs/${./f%.mp4}.mp3"; done
This did it! Shout-out to you and our programmers out there, this piece of work was not pleasant. Or it is not for me.
So I gather you got all of your .mp4 converted to .mp3. Correct?
I am finishing finishing soon. It took quite a while with a few breaks.
Thank you so much! I really appreciate it.
You are welcome.
Two things.
I need to rectify something:
for f in ./*.mp4; do ./ffmpeg -i "$f" -c:a libmp3lame "outputs/${f%.mp4}.mp3"; done
