The idea is, is that you use youtube-dl to extract the best possible audio, then put that file into the Downloaded folder (see pic below) and then you run the mp3 script (which uses commands from ffmpeg) to convert the webm file in the Downloaded folder to a mp3 file, and place it in the Converted folder.
I'll also give an explanation of how the whole thing should work.
Here is the batch script: for %%a in ('Downloaded\*.*') do %CD%\ffmpeg\bin\ffmpeg.exe -i '%%a' -vn -ar 44100 -ac 2 -ab 192k -f mp3 'Converted\%%~na.mp3' pause It appears to create an empty mp3 file that displays an error when i try to play it and the meta data is also completly blank. I've already tried using this guide on reddit to do it, but it doesn't seem to work. I would like to write a batch script that converts the webm file to an mp3 with ffmpeg. However the best quality audio usually turns out to be the webm format, which isn't useful. I'm using youtube-dl to extract the best possible audio quality from youtube videos.
