Handing off your mix shouldn't be a gamble.
The post-production landscape has changed. Between strict automated QC bots, shifting delivery bibles, and silent server-side normalization, hitting "export" feels riskier than ever. DubCheck removes the guesswork.
Server-side normalization is silent
Netflix has become more lenient on small spec misses, but instead of rejecting, they auto-normalize your mix before the viewer hears it. Your dialog level, your dynamic range, your intent: silently overridden.
Redeliveries kill your margin
A reject means that you have to reopen the session, track down the error, re-bounce, and re-upload. A single technical rejection loop on a feature film mix costs you a lot of time and real money.
Multi-platform deliveries multiply the risk
A single localized title often ships to four streamers, each with a slightly different spec sheet. Manually checking each one against the latest delivery bible is the kind of work that fails silently.
Proof of compliance
Your name is in the credits. Protect your reputation with concrete proof. The DubCheck PDF certificate serves as your technical shield against studio heads or clients. You know the file will pass before you even send it off.

Recording an audiobook for Audible / ACX?
The Studios Edition is built for streamer-grade deliveries (Netflix, Apple TV+, Disney+, Prime). If your workflow centers on audiobook submissions, the lighter AudioBook Edition covers ACX, Spotify Audiobooks, Storytel and Podtrac, at audiobook pricing.

V1 covers Netflix NOLS (including dialog-gated −27 LKFS for Originals), Apple TV+, Disney+, Prime Video, EBU R128 (broadcast), ATSC A/85 (US broadcast) and ACX. New profiles are added based on what early-access partners need. Specs are defined as data, so additions ship as quick updates rather than code releases.
For Netflix Originals (and similar dialog-gated specs), the loudness target depends on the dialog content of the file. DubCheck detects speech automatically: enough dialog measures against -27 LKFS, less dialog falls back to the -24 LKFS gate. The PDF report transparently states which gate was applied and why, so the result is auditable.
The engine implements ITU-R BS.1770-4 and is validated against the official EBU 3341/3342 reference test set. All 66 reference tests pass within ±0.1 LU tolerance. True-peak measurement uses 4× oversampling. This is the standard professional broadcasters and streaming QC houses rely on.
Yes. DubCheck runs locally on your studio machine. Files never leave the building, never upload to a server, never get cached in a cloud. Your audio is the most sensitive material in your studio, and it should stay there.
No. DubCheck is a standalone application that you install once. There is no cloud account, no server connection, no third-party data flow. ISO 27001 / TPN-certified studios can run it without going through the standard external-vendor risk-assessment process.
V1 covers 5.1, 7.1 and Atmos via 5.1 rerender, the workaround most studios use today when delivering against streamer specs that themselves are 5.1-based. Native Atmos object-level analysis depends on Dolby renderer licensing and is on the roadmap; we will not promise a date until the licensing path is clear.
Those tools are excellent loudness meters. DubCheck adds the layer above them: it knows the current Netflix / Apple / Disney+ / Prime spec sheets, runs every required check in one pass, and outputs a sign-off-ready PDF for the delivery package. You replace the manual cross-check against multiple PDFs and the Excel QC sheet with a single button.
3rd-party QC houses do content QC, watching the picture, listening for issues, catching subjective problems a tool cannot. DubCheck does measurable spec QC, the layer that should never reach the QC house in a failing state. They are complementary, not competitive. Studios using both report fewer iterations and faster sign-off.
Specs are versioned in the application. When Netflix or Apple publishes a delivery-bible update, the relevant profile is updated and shipped via app update. The exact spec version used appears on every PDF report, so the delivery is auditable years later.
Within 6 weeks of your pre-order. If we miss that window, you get a full automatic refund. The measurement engine is already EBU-certified and feature-complete. V1 is the desktop wrapper (macOS + Windows) and the studio-facing UI.
