Got it, let's break this down into actionable steps. First, a quick critical note: youtube-dl is no longer actively maintained, so I’d strongly recommend using its drop-in replacement yt-dlp instead—it supports all the same core functionality plus fixes for modern YouTube changes. That said, I’ll include notes for both tools where relevant.

Prerequisites #

First, make sure you have these installed:

• yt-dlp (or youtube-dl): Grab it via your package manager (e.g., brew install yt-dlp on macOS, sudo apt install yt-dlp on Debian/Ubuntu) or download directly from its official distribution channels.
• ffmpeg: Required to extract and convert audio formats. Install via brew install ffmpeg, sudo apt install ffmpeg, or its official installer for Windows.

Batch Scripts for Different OSes #

The core idea is to loop through each word in your list.txt file, use yt-dlp to search YouTube for that word, and download the best available audio for the top search result.

Linux/macOS (Bash Script) #

Create a file named download_audio.sh with this content:

#!/bin/bash

# Loop through each line in list.txt, skip empty lines
while IFS= read -r word; do
  [[ -z "$word" ]] && continue

  # Download top search result as highest-quality MP3
  yt-dlp \
    -x \                  # Extract audio only (discard video)
    --audio-format mp3 \  # Output file format
    --audio-quality 0 \   # Highest quality (0-9 scale, 0 = best)
    -o "%(title)s - ${word}.%(ext)s" \  # Name file with your target word
    "ytsearch1:$word"     # Search YouTube, grab the top result
done < list.txt

Then make it executable and run:

chmod +x download_audio.sh
./download_audio.sh

Windows (Command Prompt Batch Script) #

Create a file named download_audio.bat with this content:

@echo off
setlocal enabledelayedexpansion

for /f "tokens=* delims=" %%w in (list.txt) do (
  if not "%%w"=="" (
    yt-dlp ^
      -x ^
      --audio-format mp3 ^
      --audio-quality 0 ^
      -o "%%(title)s - %%w.%%(ext)s" ^
      "ytsearch1:%%w"
  )
)

Double-click the .bat file or run it directly from Command Prompt.

Customization Options #

Tweak these parameters to fit your needs:

• Get multiple results per word: Replace ytsearch1 with ytsearchN (e.g., ytsearch3 for the top 3 results).
• Change audio format: Swap mp3 with m4a, opus, or wav in the --audio-format flag.
• Filter by video duration: Add --min-duration 10 (minimum 10 seconds) or --max-duration 300 (max 5 minutes) to skip irrelevant clips.
• Save to a specific folder: Modify the -o flag to include a path, e.g., ./audio_files/%(title)s - ${word}.%(ext)s.
• Use youtube-dl instead: Just replace yt-dlp with youtube-dl in the scripts—most parameters are identical, but note that youtube-dl may fail on newer YouTube content.

Troubleshooting Tips #

• Words with spaces or special characters are handled automatically thanks to quoted variables in the scripts.
• If downloads fail intermittently, add --retries 5 to the command to retry failed attempts.
• Run yt-dlp --help to explore all available flags and options for fine-tuning.
