Mastering Engine · v7.0 · 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 the AI-detection signal on the detectors we test against. Results vary by detector and track, and detectors retrain often.

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.

    See It In Action

    Hear the difference.

    From a raw AI track to a distribution-ready master in seconds. Sound on.

    One-click Wizard

    Don't know mastering? Just pick a goal — we analyze your track and set everything up.

    Before / After

    Same track, original vs mastered — side by side. One listen says it all.

    AI-detection score drops

    Mastering also lowers our detector's score (varies by track) — helping reduce takedown risk.

    Automatic genre match

    We read your track's genre and pick the preset that fits — the right setting, automatically.

    Engineered Signal

    Built for the
    Streaming Era.

    Hits the loudness, dynamics, and headroom targets streaming platforms require — while scrambling the spectral fingerprints AI classifiers learn to flag.

    Anti-Detection Engine

    A mastering chain tuned to AI-music spectral characteristics — addresses the artefacts AI classifiers learn to flag, without touching your perceived sound.

    Sub-10s Mastering

    In-browser signal chain processes a full track end-to-end in under ten seconds — no queue, no waiting.

    Lossless 24-bit / 48k

    Studio-grade WAV / FLAC output. Distribution-ready for major streaming platforms.

    Live-Match™ Calibration

    An auto-measured linear-phase impulse-response calibration locks the downloaded master to what you hear live — bit-accurate, spectrum-matched. No more "preview vs export" surprises.

    True-Peak Limiter

    Mastering-grade limiter with lookahead, oversampled inter-sample-peak detection, stereo-linked envelope, and smooth release. Brick-wall ceiling without the squash.

    Zero-Wait Workflow

    A rolling buffer captures your live preview in the background. Calibration happens while you tweak — commit is instant. No 10-second processing screens.

    The Pipeline

    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, harmonic saturation)
    • — AI-music-specialised mastering chain (Anti-AI), verified on every export
    • — Live preview = downloaded master, 0.03 dB RMS match
    • — Processing verified to survive WAV / FLAC (lossless) and 320 kbps MP3 round-trips
    • — Mastering runs in your browser and we never keep your audio; it reaches our server only to rescue a render your browser couldn't finish (plus AI detection and the partner API), and is deleted the moment processing ends
    • — 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 processing changes the acoustic (spectral) fingerprint that detectors read. Detectors that analyse melody, structure, or generation patterns work differently and may still flag your track.
    • — Identical results on YOUR specific track. Detection scores depend on the detector, the model version and the song, and detectors retrain often — treat any number you see (ours included) as a snapshot, not a promise. Your genre, mix density, production style, and the specific detector your platform uses can yield very different results.
    • — 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.
    • — Results after heavy third-party re-encoding. Tested for WAV / FLAC / 320 kbps MP3. Lower MP3 bitrates, Opus, AAC, or aggressive re-encoding change the audio and can change detection results.
    • — 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.

    Anti-AI Master is an audio processing tool, not a legal compliance service. Always check your distributor's current AI policy before release. Full terms →

    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. It is an AI-music-specialised mastering chain — EQ, compression, harmonic saturation and limiting tuned to what AI generators typically get wrong. Changing the acoustic features detectors read is a side effect; nothing audible is added on purpose, and your listeners hear a clean, loud, streaming-ready master. Preview it free before you download.
    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 processing 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. On the detectors we test against, scores move by different amounts — sometimes a lot, sometimes a little — and 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 every export by decoding the encoded file back to PCM and checking it. Verified codecs: WAV (lossless), FLAC (lossless), 320 kbps MP3. Lower MP3 bitrates (128/192), Opus, AAC, or aggressive re-encoding by a third party change the audio, so we cannot guarantee identical results 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.
