Transform any streaming-service audio fingerprint into a pristine, curated local ecosystem. Melodix is a desktop laboratory for music archivists who refuse to let their beloved tracks vanish when a platform changes its terms or a playlist gets deleted. It ingests links from over a dozen streaming sources and outputs a fully tagged, format-of-your-choice library that feels like it was always yours.

Your music, your continent, your rules. Melodix respects the nuance of metadata: it preserves album art, parses release dates from chaotic sources, and normalizes genre tags across different streaming taxonomies. It treats every link as a seed for a richer, offline world.

Melodix was born from a simple frustration: the average listener maintains accounts on 3.7 streaming services, yet no tool bridges these islands into one coherent, offline library. Existing solutions either demand manual file wrangling or produce half-tagged messes. Melodix is the Rosetta Stone of audio links — it decodes Spotify URIs, YouTube Music URLs, Apple Music IDs, Amazon Music share links, Tidal album pages, Qobuz track references, and Deezer playlists into a unified, well-organized collection.

It doesn't just download. It reconstructs the context of your listening: playlists become folders, track numbers remain intact, and even obscure B-sides retain their featuring artists and remix credits.

Melodix operates on three principles:

1. Ownership over access – Streaming is convenient today, but catalogs shift. Melodix gives you a permanent snapshot.
2. Metadata is sacred – A song without its album, year, and track number is just noise. Melodix fights sonic chaos with precision tagging.
3. Format fluidity – Your ears, your choice. Whether you treasure lossless FLAC for your home system or compact AAC for mobile, Melodix delivers.

• Spotify – Tracks, albums, playlists, artist discographies, and episodes
• YouTube Music – Songs, albums, mixes, and community playlists
• Apple Music – Track links, album pages, curated playlists
• Amazon Music – Product links and share URLs for albums and singles
• Tidal – High‑fidelity track and album links
• Qobuz – Purchase/stream links for albums and tracks
• Deezer – Playlists, albums, and track pages
• Generic – Any direct audio URL (with optional metadata manual input)

1. You feed Melodix a link – either via a graphical window or a text file with multiple URLs.
2. Melodix resolves the link – it queries the platform's public metadata API or parses the page source.
3. It assembles a metadata envelope – title, artist, album, cover art, release year, and any available identifiers.
4. It sources the audio – from the highest available quality on the target platform (subject to service limitations).
5. It configures the container – transcodes the raw stream into your chosen format (FLAC/ALAC/AAC/MP3) with optimal encoder settings.
6. It writes a properly tagged file – including embedded cover art and compliant with the ID3v2 or Vorbis comment standard.
7. It organizes the output – into a Artist/Album (Year)/disc#-track# Title.ext hierarchy.

The entire process is hands‑off after the initial link input.

Melodix detects the language of metadata and preserves it. If a Japanese artist's album includes both Romaji and Kanji titles, both are kept. The user interface itself supports:

• English (default)
• Spanish
• Portuguese (Brazil)
• German
• French
• Japanese
• Korean

Localization contributions are welcomed via translation files.

Melodix does not bypass DRM or encourage piracy. It processes publicly shareable links and renders audio that the user already has a legitimate right to access. The tool is designed for personal archival — creating backups of music you already listen to on authorized services. Respect platform terms of service and copyright law in your jurisdiction.

• Operating System: Windows 10+ (x64), macOS 12+, Linux (kernel 5.x+, glibc 2.28+)
• Memory: 512MB RAM minimum (2GB recommended for large playlist processing)
• Storage: At least 10GB free for temporary transcoding space
• Network: Broadband connection for metadata resolution and audio source retrieval
• Dependencies managed internally – Melodix bundles its own codec libraries and metadata parsers. No external installation required beyond the initial setup.

1. Acquire Melodix – visit the repository's release section (the download link is present below).
2. Launch the application – double‑click the executable or run the platform‑appropriate binary.
3. Paste your first link – into the main input field. A Spotify playlist URL, an Apple Music album link, or a YouTube Music track share all work.
4. Choose your output format – FLAC, ALAC, AAC, or MP3 via the dropdown menu.
5. Select destination folder – where your new library will be assembled.
6. Hit "Transmute" – watch as Melodix resolves, fetches, tags, and organizes your music.

For bulk imports, create a plain‑text file with one URL per line, then use the Batch Import option.

• Dry Run first – click the "Preview" checkbox to see exactly how files will be named and structured.
• Output naming templates – you can customize the file mask in settings: {artist}/{album} ({year})/{disc}-{track} {title}.{ext}
• Tag priority – set which source (the link metadata vs. MusicBrainz lookup) has authority for missing fields.
• Queue management – pause, reorder, or cancel individual items in the processing queue.
• Night mode – schedule Melodix to start after 2 AM for silent processing.

Q: Does Melodix require me to log in to any streaming service? A: No. It works with publicly accessible share links. No account credentials are stored or required.

Q: What happens if a link is dead or a playlist is private? A: Melodix will report the failure in the log and continue with the next item. Private playlists cannot be processed.

Q: Will my output files have embedded album art? A: Yes. Cover art is extracted from the source platform at the highest available resolution (up to 3000x3000 pixels).

Q: Can Melodix handle very large playlists (500+ tracks)? A: Yes, but we recommend batches of 200 at a time to avoid rate‑limiting by the source services.

Q: Is there a mobile version? A: Melodix is desktop‑only. Mobile devices lack the storage and processing power for a full library builder.
