To download only the audio in the best possible quality for each YouTube link listed in your text file, you can use the following command with yt-dlp:

yt-dlp -f bestaudio --extract-audio --audio-format mp3 --batch-file="your_file.txt"

Explanation:

  • -f bestaudio: Ensures the best available audio format is selected.
  • --extract-audio: Extracts the audio from the video.
  • --audio-format mp3: Converts the extracted audio to MP3 format. You can change this to other formats like m4a or wav if needed.
  • --batch-file="your_file.txt": Specifies the path to your text file containing the list of YouTube links.

Additional Notes:

  1. Replace your_file.txt with the actual path to your file.
  2. If you want the audio in its original format without conversion, omit the --audio-format option and just use --extract-audio.

Example Command for Original Audio Format:

yt-dlp -f bestaudio --extract-audio --batch-file="your_file.txt"

This will download the audio in its highest quality without converting it.
