Guides on loudness standards, platform specs and audio delivery. Written for narrators and mix engineers who want to get the file right the first time - instead of redelivering after rejection.
We cover the things the platform spec sheets do not: why ACX rejects a chapter even though your DAW says it is in spec, what a Netflix dialog-gated measurement actually does to your numbers, where EBU R128 short-form differs from long-form, how an inter-sample peak ends up 2 dB above what your meter showed, and the day-to-day workflow choices that quietly drag a master out of compliance.
Every article is written against the same EBU 3341/3342 certified measurement engine that ships inside DubCheck - so the numbers you read here are the numbers the audit will hold you to.
Articles, not press releases.
Most loudness writing online either reprints a platform spec sheet or copies the wrong numbers from a forum thread from 2014. We do not do that. Each article on this site is written against a single source of truth - the measurement engine inside DubCheck - and the numbers in the article match the numbers a working audit will produce on the same file.
Topics we keep coming back to: how the platforms actually measure (gating, dialog detection, weighting), where the major delivery specs disagree with each other and what that means for a master, common workflow traps (dither, channel order, sample-rate conversion), and the failure modes that look fine in a DAW but get caught in QC.
