SoundTech

Finding high-quality audio shouldn't feel like a chore. Most scrapers return variable bitrates and messy tags that clutter your library. This skill automates the process of fetching 320kbps MP3s from YouTube and SoundCloud with professional-grade ID3 tagging.

What it does

• Automated tagging fetches missing album data and artwork via the iTunes Search API.
• High-fidelity encoding forces 320kbps MP3 output using ffmpeg for consistent audio quality.
• Bulk processing handles song lists, entire YouTube playlists, and SoundCloud albums.
• Smart matching verifies tracks using duration tolerance and title keyword analysis to filter out live or acoustic versions.
• Interactive selection provides a picker when multiple versions of a song are found, ensuring you get the exact release you want.

How it works

1. Trigger the script by providing a URL, a song name with artist, or a path to a text file list.
2. Resolve ambiguities if the agent prompts with a list of candidates; choose the correct index to proceed.
3. Download and tag as the agent invokes the local Node.js script to fetch media and embed metadata.
4. Verify output via ffprobe to confirm the 320kbps bitrate and proper artist/album fields.

Frameworks & tools

Requires Node.js, yt-dlp, and ffmpeg installed on the system PATH. Uses the iTunes Search API for metadata enrichment.

Why this beats prompting it yourself

Writing a prompt to download audio usually results in low-quality rips or broken metadata. This skill leverages a purpose-built Node.js script that handles edge cases like age restrictions, duration verification, and ID3 art embedding that standard LLMs cannot do through text alone.

Use cases

• Library building by converting a text list of tracks into a tagged MP3 collection.
• Playlist archiving to back up entire YouTube or SoundCloud playlists locally.
• High-quality sourcing for DJs or collectors who require verified 320kbps files.

Known limitations

YouTube age-restricted videos require a pre-configured cookies.txt file or specific browser profile access. The script requires a local environment with media tools installed to function.
