Verified release notes for the Intrect plug-ins. This page lists only versions that passed the release audit without a known blocking regression. Withdrawn builds and source-only versions are omitted; the download page always points to the current release.

ENZYME 0.3.1

2026-08-24 · Recommended · macOS Universal · Notarized + stapled

New

Mono instances. ENZYME loads on mono tracks as a 1-in/1-out plug-in with a mono sidechain. Stereo-only behaviour — mid/side processing and channel link — does not apply on a mono instance, and the spectrum legend no longer labels a mono signal as M/S.

Fixed

Mono Audio Unit editor. A mono AU instance opened an empty plug-in window in Logic. The mono layout declared a stereo sidechain bus, but a host negotiates the sidechain at the instance width — Logic asks for a mono sidechain on a mono track. The rejected format made Logic drop the instance before it ever asked for the editor, with no error shown. The sidechain now matches the instance width.

0.3.0 introduced the mono layout but shipped with that regression and was withdrawn; 0.3.1 replaces it. Windows remains on 0.2.1 until its build host is back.

14-day free trial. Download from the download page, or read the spec sheet.

ENZYME 0.2.1

2026-08-18 · First public release · macOS Universal · Notarized + stapled

New plug-in

Dynamic resonance suppression. Estimates a per-bin spectral baseline and attenuates only what protrudes above it, per frame — so a resonance is pulled down while it rings and everything else at that frequency passes through.
Harmonic / percussive / residual de-mix. An optional second stage separates the signal into three components with independent cut amounts, a 7–31 bin median kernel, three mask modes, and solo monitoring per component.
Native AUv2, VST3 and CLAP. The Audio Unit is a real component rather than a wrapped CLAP, so Logic and GarageBand load it directly.
Delta and Bypass monitoring. Delta plays only what is being removed. Both keep the reported 2047-sample latency, so A/B stays phase-aligned.

Fixed since 0.2.0

Audio Unit knob writes. Moving a control in the editor now retargets the parameter smoother, so edits made from the GUI take effect in AU hosts.

14-day free trial. Download from the download page, or read the spec sheet.

de-artifact 0.3.10

2026-08-15 · Recommended · macOS + Windows

Fixed

Logic Pro AU silence. Corrected two host-buffer contract errors in the input pull path. Logic Pro playback was verified with the corrected wrapper.
Windows installation checks. The installer now detects the Microsoft VC++ 2015–2022 x64 runtime and Windows 10 2004+ requirements before installation, instead of allowing a plug-in that cannot load to appear installed.

Existing licenses carry over. Update from the download page.

de-artifact 0.3.9

2026-08-13 · Verified release · macOS Apple Silicon

Fixed / improved

Native inference self-check. The native path is compared with the CPU reference at load time and falls back automatically when outputs disagree.
Active engine visibility. The editor and diagnostic report now show which inference backend is active.
Shipping-build QC. AU validation now exercises the same feature and model configuration used for release builds.

The self-check is a mitigation for one Apple Silicon silence path, not a claim that every possible silence cause is fixed.

de-artifact 0.3.8

2026-08-04 · Verified release

Added

In-plugin update check. The editor can show when a newer channel release is available without sending device or version telemetry.
Improved display formatting for dB controls.

Verified legacy releases

Kept for reference; not the current recommendation

0.1.8 — fixed AVX2 Windows audio dropouts by wiring the multithreaded executor.
0.1.3 — installer path and version sourcing fixes.

Release policy

Versions with confirmed blocking regressions are intentionally not listed here. If you are on an older build, install 0.3.10 and restart or re-add the plug-in in your DAW. If a problem remains, open a support ticket with the host, OS, and diagnostic report.

License model: trial-then-paid

We moved back to a 14-day full trial model and retired the always-on freemium gap. The trial is bound to a machine fingerprint (no email, no account), so launching a fresh install on a machine just works for 14 days at full quality with no audible limits.

14-day full trial. First launch on a machine calls /v1/trial on license.intrect.io; the server issues a signed blob bound to the machine's fingerprint with a 14-day expiry. Re-installs on the same machine reuse the original expiry — no clock reset. Reinstalling the OS may reset machine identity and re-issue the trial; we accept that as a reasonable evaluation path.
Gate after expiry. Once the 14-day trial elapses, the plug-in continues to run but inserts a brief silent gap roughly every 60 seconds until you activate it with a license key. The previous "always-on, 250 ms every 10 s" gap is gone.
Activate flips the trial blob to paid. A purchase email delivers the license key; pasting it in the plug-in's license badge calls /v1/activate, rewrites the on-disk blob to a paid blob (tier byte = 0x00, no expiry), and removes the gate immediately — whether you're on day 1 or past day 14.

de-artifact 0.1.2

2026-05-08 · macOS 11+ · Notarized + stapled

Changes

Apple notarization complete. Installer is signed with our Developer ID Installer certificate (Heewon Oh, team 635QK74RYK) and the notarization ticket is stapled into the .pkg. Double-click installs without the “unidentified developer” Gatekeeper dialog — no more right-click + Open workaround.
Behaviour, models, presets, and parameters unchanged from 0.1.1.

de-artifact 0.1.1

2026-05-08 · macOS 11+ · Universal binary (Apple Silicon + Intel)

Changes

Universal Binary. Single .pkg now ships arm64 + x86_64 slices. Intel Macs no longer need a separate build path; file(1) on the installed bundle reports both architectures. Installer size grew from ~65 MB to ~132 MB; on-disk install grew correspondingly to ~150 MB.
System requirements updated to reflect the new Architecture row.
Behaviour, models, presets, and parameters unchanged from 0.1.0.

de-artifact 0.1.0

2026-05-08 · macOS 11+ · Apple Silicon

First public build. Real-time VST3 / CLAP plug-in for cleaning RVQ ghosting and codec residue from AI-generated music.

Highlights

HPSS analysis + ArtifactUNet mask + adaptive spectral subtraction in a single audio block.
Two latency modes — Standard (500 ms, ~3× realtime headroom on M1) and Low-latency (~186 ms, ~1.7× headroom). Toggleable at runtime.
Seven presets tuned per source type (Suno, Udio, DiffRhythm, transient-heavy, vocal, master, aggressive).
Diff mode for residual auditioning. HPSS harmonic / percussive focus modes.
Licensing at this build: always-on freemium gap (250 ms every 10 s). Superseded on 2026-05-10 by the 14-day trial model — see the platform note above.

Known issues at release

Installer was not yet Apple-notarized at this point. Resolved in 0.1.2.
Windows / Linux builds on the roadmap.

de-leak-rt 0.1.3

2026-05-08 · macOS 11+ · Notarized + stapled

Changes

Apple notarization complete. Installer is signed with our Developer ID Installer certificate (Heewon Oh, team 635QK74RYK) and the notarization ticket is stapled into the .pkg. Double-click installs cleanly with no Gatekeeper dialog.
Behaviour, models, presets, and parameters unchanged from 0.1.2.

de-leak-rt 0.1.2

2026-05-08 · macOS 11+ · Universal Binary

License server, downloads, telemetry

Backend infrastructure milestones leading up to the public launch. These changes are invisible to end users but worth recording for transparency.

Email-based trial system retired. The original 14-day email-Turnstile trial (/v1/trial-request) was removed in favour of a forever-free demo with a 250 ms silent gap every 10 s — no email friction, no abandoned trials. Superseded on 2026-05-10: the freemium gap was replaced with a no-email, machine-fingerprint-bound 14-day full trial via the new /v1/trial endpoint. See the 2026-05-10 platform note at the top of this page.
145-byte signed license blob. Server-side blob layout finalized in lockstep with the plug-in's intrect-license Rust crate: ed25519 signature, expiry, machine fingerprint, license key, reserved bytes. Refresh deadline ~14 days; quietly renewed in the background while the plug-in is loaded.
Paddle webhook hardening. HMAC verification with a 5-minute replay window; handles transaction.completed, transaction.refunded, and subscription.canceled.
Download CDN. Installer files are served from downloads.intrect.io through a Cloudflare Worker that proxies R2, honours Range requests, and writes one telemetry row per request to the new intrect-telemetry D1 database.
Turnstile-gated downloads. The .pkg URL only releases the binary if the request carries a verified Cloudflare Turnstile token, issued by the /download/<plugin>/ interstitial page. Stops bot scraping and dataset crawlers from pulling the installer.
Daily rollup cron. Raw download events are aggregated nightly into the daily_rollup table; raw rows older than 30 days are pruned.
Read-only metrics endpoint. metrics.intrect.io exposes per-path / country / referral aggregates over a Bearer token, for the operator only.
Site SEO + Core Web Vitals pass. JSON-LD FAQPage + BreadcrumbList + WebSite on the marketing pages, OG/Twitter tags consolidated, Paddle script deferred, hero images width/height + fetchpriority for LCP, immutable cache on static assets.
