# This simple Bash script lets you download the video
# using yt-dlp, and then takes care of extracting its
# audio into a file for each song w/ ffmpeg!

# It does not re-encode or tag any of the audio files
# due to raw preservation being its purpose.

# You should run it line by line rather than blindly!
# Feel free to tweak & suggest improvements!

# ---------------------------------------------------

# We'll be using the ID for both file and directory.
VIDEO_ID='4cEKAYnxbrk'

# Create and enter the new directory.
mkdir -p "${VIDEO_ID}" && cd "${VIDEO_ID}"

# Download the audio file using yt-dlp.
yt-dlp -x -f bestaudio "${VIDEO_ID}" -o "${VIDEO_ID}.%%(ext)s"

# Figure out the downloaded file name and extension.
SRC_FILE=$(ls "${VIDEO_ID}".*) # ls command should only output the downloaded file name!
FILE_EXT=${SRC_FILE:12}        # file id + dot = 12 characters; extension length varies!
