§ Why DubCheck exists

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

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

DubCheck does that check for you. Drop a file in, pick a target, 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.

Everything happens locally. Files never leave your machine: no upload queue, no cloud storage of confidential mixes, no telemetry. The PDF report 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.
