Flac.Audio Documentation
Complete technical reference for lossless Beatport downloads, automated DJ metadata tagging, the Spotify Crate Matcher, 1-click Rekordbox XML exports, and club hardware standards.
1. Overview & Platform Architecture
Flac.Audio is a cloud-based productivity platform engineered for touring DJs, electronic music producers, and audiophiles. It solves the single biggest bottleneck in modern DJ prep: time-consuming single-track downloads, manual ZIP extraction, and error-prone tagging of musical keys, BPM values, and high-resolution cover art.
No desktop software or local CLI scripts required. All transcoding, metadata embedding, and ZIP archiving run asynchronously on dedicated high-performance server clusters.
FLAC and AAC files come directly from store CDN streams. WAV and AIFF are bit-perfect 16-bit PCM transcodes of this master FLAC file — never re-recorded soundcard captures.
2. Quickstart in 3 Steps
- Paste Link or Search: Enter any Beatport track, release, or chart URL into the Web Downloader. The same page searches the catalog by artist or title.
- Select Audio Format: Choose FLAC, AAC, AIFF, or WAV depending on your CDJ player compatibility.
- Download & Play: Individual tracks stream directly to your browser. Entire releases, playlists, and Spotify crates download as clean, pre-tagged ZIP archives.
3. Audio Formats & Club Hardware
Flac.Audio supports four industry-standard formats tailored for touring sound systems and DJ software:
| Format | Specs & Bitrate | Plan Availability | Recommended Hardware |
|---|---|---|---|
| FLAC (Lossless) | 16-bit / 44.1 kHz | All Plans (including Free) | Pioneer CDJ-3000, CDJ-2000NXS2, Denon Prime OS |
| AAC (High Quality) | 256 kbps VBR | All Plans (including Free) | Universal club standard across all players (compact USB storage) |
| AIFF (PCM + Artwork) | 16-bit Uncompressed PCM | Pro & Premium | Studio PCM with native ID3v2.4 tags & 1400px artwork support |
| WAV (Linear PCM) | 16-bit Linear PCM | Pro & Premium | 100% of all CDJs, including legacy hardware (CDJ-900, CDJ-2000 mk1) |
4. Automated DJ Metadata Tagging
Every downloaded file passes through our server-side metadata pipeline. We write strict, standardized ID3v2.4 frames and FLAC Vorbis comments:
- Harmonic Key (Camelot Notation): Keys are written directly to the KEY and INITIALKEY frames (e.g.,
8A,11B). Rekordbox, Serato, and Traktor load these instantly without slow key-detection scans. - Accurate BPM & Grid Foundation: Official tempo markers are stored so DJ software aligns the beatgrid precisely on the first beat.
- Sharp 1400×1400 Album Artwork: Full-resolution square cover art is embedded, optimized for the high-DPI displays of the Pioneer CDJ-3000, XDJ-XZ, and Opus Quad.
- Label, Genre & Release Date: Full catalog metadata ensures dynamic smart playlists and intelligent crate sorting work out of the box.
5. Web Downloader & Batch Crates
The Web Downloader on /dashboard supports direct URL input and real-time catalog search:
Instant browser download of the fully tagged audio file in your selected format.
Concurrent download of all release tracks bundled into a single organized ZIP package.
Up to 100 tracks per batch. Perfect for Top 100 genre charts and gig crate prep.
Duplicate Detection: The system automatically flags tracks that already exist in your personal library to prevent accidental credit consumption.
6. Spotify to Beatport Crate Matcher
Use the Spotify Matcher at /spotify-matcher to turn streaming playlists or setlists into lossless DJ crates:
- Paste any public Spotify playlist URL or raw text tracklist (e.g. from 1001Tracklists or Shazam).
- Our search engine queries the Beatport catalog and automatically prioritizes club-ready Extended Mixes.
- Harmonic Crate Sorting: Automatically organize matched results by the Camelot Wheel (e.g. 8A → 9A) or BPM for flawless transitions.
- Download individual tracks or export the whole set as a single ZIP archive (Pro & Premium).
7. DJ Library & 1-Click Rekordbox XML Export
Every downloaded track is permanently logged in your private dashboard at /library:
- Collection Management: Filter your historical archive by artist, track title, genre, key, or BPM.
- Preview & Re-Download: Re-listen to preview snippets or re-download previously purchased tracks without spending extra credits.
- 1-Click Rekordbox XML Export: Click "Export Rekordbox XML" to download your complete library or current filter view formatted for Rekordbox.
- Import into Rekordbox: In Rekordbox, navigate to File → Import Playlist → Rekordbox XML. All tracks, cue points, beatgrids, and playlists appear instantly.
8. Download Queue & Background Batch Jobs
Large downloads (playlists, charts, full album releases) process as asynchronous background jobs so your browser remains completely responsive:
Track job progress in real time at /jobs (queued, processing, completed), see downloaded track counts, and re-download completed ZIP packages whenever needed.
9. Rekordbox, Serato & USB Club Preparation
Follow this checklist to move downloaded audio files seamlessly from your computer to club-ready USB drives:
1. USB Drive Formatting
Format your USB flash drive as FAT32 (for universal compatibility across all legacy CDJs) or exFAT (for modern players like the CDJ-3000 and Opus Quad).
2. Import into Rekordbox (2 Options)
Option A: Drag and drop downloaded FLAC, AIFF, or AAC files straight into your Rekordbox Collection.
Option B: Use the 1-click XML export from your library (/library) for automatic playlist and tag synchronization.
3. Sync Manager Export
Open Sync Manager in Rekordbox, select your target playlists, and click sync to write the CDJ database to your USB drive. Plug into the booth and play.
