- Auto-repair: loudness, true-peak ceiling, conservative high-pass
- Reference matching, metric by metric
- Batch / album passes
- HTML + JSON engineering reports
- TXT summaries auto-written beside each bounce
- Drag-drop
.batanalyzer — one-time, forever - Same scoring engine as the A/B demos (70→90, 77→95, 66→93)
- Latest NoDAW Liminal desktop included — downloads the current GitHub release. Liminal then checks itself for updates.
Checkout runs on the NoDAW Labs store (nodawlabs.com).
- Everything in Pro
- Multiple seats on one purchase conversation
- Album-consistency and delivery checklists at scale
- Help wiring reports into your existing bounce folder
- No mandatory cloud, no per-track mastering fee
Demo vs Pro.
The website proves the meters. The desktop app is where repair writes a file you can bounce.
| Capability | Demo / web | Pro desktop |
|---|---|---|
| Hear before / after A/B | Yes — three real pairs | Yes — your sessions |
| Score, LUFS, true peak, clips, phase | Yes (engine API) | Yes |
| Projected repair column | Yes | Yes, then you can apply it |
| Write a repaired WAV | No (by design) | Pedalboard / FFmpeg |
| Reference match | Not on the web form | Full divergence table |
| Batch / album | One file at a time | Yes |
| HTML + JSON reports | On-screen report | Exportable |
| Audio leaves your machine | Only if you use the optional local API | Never required |
| Price | $0 | $29 one-time |
Why it is not $15/mo.
LANDR-style services charge rent to upload an unreleased master. CoProducer is a local instrument. You buy the engine once.
Pro is a lifetime license at $29. There is no Starter subscription and no per-track cloud fee on this page — those would fight the rest of the product. Studio is a conversation when you need extra seats, not a third monthly SKU.
Before you pay.
Is Pro monthly?
No. $29 once. The old three-tier monthly mock on this URL was a placeholder and did not match the product.
Do I need the web API?
Only to try Analyze in the browser. The desktop app is the real engine: same scoring, plus repair that writes a file.
Will repair restore clipped transients?
No. The report will say so. Limiting can zero the clip count; it cannot un-flatten a peak. Go back to the session when you still can.
