§ Why DubCheck exists

Built by a mix engineer, for the people who have to ship the file.

Every audio delivery sits behind a wall of numbers - integrated loudness, true peak, dialog gating, LRA, channel order, sample rate, dither, phase correlation. Get one wrong and the file gets bounced. The platform never tells you which one; you have to guess.

DubCheck does that check for you. Drop a file in, pick a target - ACX, EBU R128, Netflix NOLS, Apple TV+, Disney+, Prime Video, Spotify, Audible, Storytel, Podtrac - and you get a pass/fail in seconds with every measurement annotated against the spec. No silent failures, no "why does my DAW disagree with the platform meter" rabbit holes. The engine is EBU 3341/3342 certified and matches the reference tone-set bit-for-bit on all 66 conformance tests.

Everything happens locally. Files never leave your machine, no upload queue, no cloud storage of confidential mixes, no telemetry. The PDF report it generates is the same one you hand to a client or attach to a delivery portal - readable by humans, signed off by the engine, and complete enough to settle a redelivery dispute on its own.
