Industrial-grade local audio governance and next-gen all-in-one asset workstation
PureLab is an industrial-grade asset manager built for music collectors, producers, DJs, sound designers, and audio professionals. Version 5.0 ships Pipeline automation—paired with on-device AI, Tag Bridge, hardcore snapshots, and Hollywood-grade UCS—so chaotic local files become a production-ready library that plugs into your pro tools.
The 5.0 headline. Orchestrate Action Groups that chain extract, Replace, CJK, and write-back as lightweight nodes. Millisecond cleanup against existing tags—normalize the whole local library in one click, with no deep scan or AI wait.
Modern sidebars, split panes, and high-density views, with every core tool a shortcut away. Rendering and data structures are tuned for tens of thousands of assets, so batch select, preview, and edit stay fluid.
One-click UPPERCASE, lowercase, or Title Case for titles, artists, albums, and filenames. A CJK engine handles Pinyin, Simplified/Traditional conversion, and Japanese/Korean romanization. Precision Replace strips site suffixes and unifies numbering in seconds.
On-device AI extracts genre, style, mood, and instruments. Tag Bridge writes those dimensions into the audio file so Rekordbox and local hi-fi players read them natively. Professional BPM and Camelot detection run in batch.
Rename files and rebuild folders from tags such as artist, album, and title. Embed artwork and lyrics in bulk. Every edit is kept, with instant single-track or multi-select rollback plus library-wide snapshot disaster recovery.
Native Hollywood UCS with bidirectional parse—extract from folders and filenames back into tags. Read and write BWF metadata for film and broadcast. Excel import/export makes large-project handoff straightforward.
A floating audition basket auto-converts selected assets when you drag into Logic, Ableton Live, or DJ software. CLAP powers search-by-text and search-by-sound so you can pull inspiration from the local library in seconds.
True-source analysis with spectrum scoring and cutoff-frequency detection, plus waveform and spectrogram views—no more fake lossless. Compatible with WAV, FLAC, MP3, AAC, OGG, DSF, DFF, and other audiophile formats.
AI models and search algorithms ship inside the app and keep working with the cable unplugged. We never upload your sessions, music files, or search queries.
No. All analysis models and search algorithms are bundled in the app and run at full power offline. We never upload your project assets, music files, or search text.
