Mastering Engine · v5.0 · Live-Match™

AI music mastering, tuned for streaming. Built for Suno · Udio · every model.

A studio-grade mastering chain tuned to the spectral characteristics of AI-generated music — fixing the low-mid muddiness, harsh top end and stereo issues that AI music typically carries. Delivered as 24-bit / 48 kHz lossless masters in under 10 seconds.

Bonus — the same chain reduces AI detection signal on the detectors we test against (internal v18: ~−25 pt average; specific external detector case: 99→11%). Variance by detector and track.

Powered by Live-Match™ Calibration — auto-measured impulse response that locks the downloaded master to the exact character you heard in the live preview. The only mastering platform that does this.

What we guarantee · What we don't

We measure what we ship. We don't oversell what we can't control.

We guarantee 6
  • — Studio-grade mastering chain (Match-EQ, True-Peak limiter, multiband)
  • — AI-music-specialised mastering chain (Anti-AI v7) with inaudible ultrasonic watermark layer, verified per export
  • — Live preview = downloaded master, 0.03 dB RMS match
  • — Watermark survives WAV / FLAC (lossless) and 320 kbps MP3 round-trips
  • — Mastering runs 100% in your browser; AI detection uses a temporary upload that's deleted immediately after analysis
  • — 7-day refund on unused credits (14 days for EU/UK consumers); auto-renew cancellable anytime in your account
We don't guarantee 7
  • — Effectiveness against content-based AI detectors. Our watermark disrupts spectral fingerprints. Detectors that analyse melody, structure, or generation patterns work differently and may still flag your track.
  • — Identical results on YOUR specific track. Our internal v18 average ~−25 pt drop and specific external detector case (99→11%) are measured on Suno V3/V4 (internal live measurement, 2026-05). Your genre, mix density, production style, and the specific detector your platform uses can yield very different numbers.
  • — Outcomes on third-party platforms. Major streaming platforms and distributors make their own decisions independently. Track removal, demonetization, or rejection are outside our control.
  • — Future classifier behaviour. Detectors retrain continuously. Today's score reduction may shrink as classifiers learn the patterns our pipeline uses.
  • — Watermark survival outside the verified codecs. Tested for WAV / FLAC / 320 kbps MP3. Lower MP3 bitrates, Opus, AAC, or aggressive re-encoding may degrade or remove the watermark.
  • — Copyright or licensing of AI-generated source material. Compliance with the AI generator's ToS (Suno, Udio, etc.) and your distributor's AI policy is your responsibility.
  • — Continuous service availability. Service is provided on a best-effort basis with no formal SLA. Brief downtime for maintenance or third-party outages does not entitle you to a refund.

Questions

What you might be wondering.

Honest answers about how the pipeline works, what it can and can't do, and where the limits sit.

No, and we don't pretend otherwise. Classifiers retrain. We continually monitor major external AI detectors and tune the pipeline as they evolve. Monthly Unlimited subscribers get free re-renders whenever the chain is updated.
No. The processing combines multiband compression, harmonic saturation, and an inaudible ultrasonic watermark layer — all outside the audible range. Classifiers rely on spectral statistics we shift; your listeners hear a clean, loud, streaming-ready master.
Input: WAV, FLAC, AIFF, MP3 — up to 32-bit float / 96 kHz.

Output by plan:
• Single Download (1 cr) — 24-bit / 48 kHz lossless WAV, FLAC, or 320 kbps MP3 (pick one).
• Pro Delivery Set (2 cr) — all three formats in one zip.
• Premium Render (4 cr) — 96 kHz / 32-bit float master, real-time captured from the live chain. The Pro Delivery zip is bundled in.

Try / Starter / Creator Pack credits never expire. Pro and Studio monthly plans refresh each billing cycle.
Distribution policy is between you and the DSP. We don't disclose your inputs to anyone, and our masters meet the loudness/format specs major DSPs typically require. Some distributors accept AI-assisted music — policies vary widely and change often, so check the current terms on the exact distributor and platform you ship through before release. This is a tool, not a legal shield.
Same mastering chain across every tier — only the credit volume and extra features differ. Try ($2.99) gives 5 credits — perfect to taste Premium Render. Starter ($9.99) gives 20 credits with no expiry. Creator Pack ($29.99) gives 75 credits — best per-credit value in one-time packs. Pro ($19.99/mo) gives 70 credits/month with auto-renew. Studio ($39.99/mo) is unlimited credits + priority queue. 1 credit = 1 single download (WAV/FLAC/MP3); Pro Delivery Set (zip with all 3 formats) = 2 credits; Premium Render (96 kHz / 32-bit float) = 4 credits. Cancel monthly plans anytime.
Single Download / Pro Delivery — under 10 seconds per track on typical files; longer tracks (over 5 minutes) may take up to 30 seconds.

Premium Render — runs in real time from the live chain, so it takes roughly the song's playback length plus a few seconds of finalisation. A 3-minute track ≈ 3 minutes; a 5-minute track ≈ 5 minutes. You can leave the tab open and come back.

Multiple tracks process sequentially — submit, walk away, come back to download.
We can't promise that. Major streaming platforms and distributors make their own decisions about AI-generated music — we have no control over those decisions, and policies evolve regularly. Our watermark reduces classifier confidence on the detectors we test against; it does not override platform terms of service. Always confirm the current AI policy on the exact platform and distributor you're shipping through before release.
No. Our chain is first an AI-music-specialised mastering tool — detection-score reduction is a side effect. Internal live measurement (2026-05) on Suno V3/V4: average ~−25 pt drop on our internal v18 detector. Specific external detector case observed: 99→11% (−88 pt). Some external detectors register only a −30~40 pt drop — detector-by-detector variance is large. Two important caveats: (1) classifiers retrain continuously, so today's numbers may shift, and (2) content-based detectors that analyse melody, song structure, or generation patterns work differently and may still flag your track. Treat the processing as a layer of defence, not a final verdict.
We verify watermark presence on every export and round-trip the encoded file back to PCM to confirm. Verified codecs: WAV (lossless), FLAC (lossless), 320 kbps MP3. Lower MP3 bitrates (128/192), Opus, AAC, or aggressive re-encoding by a third party may degrade or remove the watermark — we cannot guarantee survival outside the verified codecs.
Platform decisions are independent of our service. We offer a full refund within 7 days of purchase — provided you haven't downloaded a master yet (once you download, that credit is used and non-refundable). Beyond that window we can't refund based on third-party platform actions (track removal, demonetization, account suspension), because those decisions are not under our control. Anti-AI Master is an audio processing tool, not a platform-compliance service.
