# TrackGleam

> TrackGleam (formerly Auracle) is a free, privacy-first online audio mastering tool that runs entirely in the user's web browser. It masters music (MP3/WAV) with a professional 14-stage chain — no upload, no account, no signup, no watermark on free masters. Masters target release-competitive loudness (Auto ≈ -11 LUFS integrated; genre styles from -9 for EDM/hip-hop to -15 for classical; the Low intensity gives a traditional -14 LUFS streaming-safe master) at a -1.0 dBTP true-peak ceiling — ITU-R BS.1770-4 gated, measured on every master. An optional paid GleamAI master ($1.99 one-time; Creator Pack 10 for $5, credits never expire; or the Producer subscription — unlimited GleamAI masters, fair use applies — at $8.99/month or $89.99/year) unlocks a premium AI-tuned, watermark-free download. Gleam corrects your track; GleamAI makes decisions about it. AI voice cleanup (RNNoise neural noise suppression, on-device) lives at /voice. Website: https://trackgleam.com

## Key facts
- All audio processing is client-side (Web Audio API); recordings never upload. Only numeric analysis is sent for AI masters.
- The free master is the finished deliverable, not a preview: full-length 24-bit WAV with TPDF dither, no watermark, no account, as many single-track masters as you like.
- Free and paid masters run the identical 14-stage chain and the identical measurement loop; GleamAI differs in the decisions it makes, not in the grade of processing.
- GleamAI reaches for four stages the free chain never runs — linear-phase finishing EQ, resonance smoothing, a 3-band tonal balancer, and multiband stereo width — each engaged only when the measurements call for it.
- GleamAI cannot return a master thinner or quieter than the free one: the paid render is floored to the free master's low-end and loudness baseline, and any move that measures worse after rendering is reverted.
- Reported loudness and true peak are read off the finished file after the last processor, verified against EBU R128 / Tech 3341 and ITU-R BS.1770-4 reference signals.
- Bulk mastering (a whole release at once, unlimited files, ZIP export) is a Pro perk unlocked with any paid purchase — kept forever.
- Loudness standard: ITU-R BS.1770-4 gated integrated loudness; true peak via 4x polyphase oversampling (BS.1770 Annex 2).
- Podcast/voice preset targets -16 LUFS (Apple Podcasts spec) at -1.0 dBTP.
- Credits are account-free redeemable codes; 14-day money-back guarantee on one-time purchases (Producer subscription: cancel anytime).
- Names: the free engine is Gleam; the paid tier is GleamAI.
