Measurements you can trust

Every file is measured for program and dialog-gated loudness, loudness range, maximum momentary and short-term loudness, and maximum true peak, with format checks on sample rate, bit depth and channel layout, and advisory checks for DC offset, silent or mis-routed channels and L/R phase correlation. The glossary defines each of them, and every measurement name in your results links straight to its entry.

DeliveryQC runs on MeterPlugs' professional ITU-R BS.1770 / EBU R128 metering engine — the same DSP behind our loudness plugins. It is validated against the published compliance test signals, ITU-R BS.2217 and EBU Tech 3341 / 3342, matching the specified targets within tolerance for every layout this tool supports. Dialog-gated loudness uses Dolby Dialogue Intelligence — the speech-gating method the platforms specify, not an approximation.

Private by design

Analysis runs entirely in your browser — your audio is never uploaded to a server. We do collect anonymized metrics such as the resulting loudness, true-peak and duration for usage analytics, but not filenames, audio, or other information that would identify you or your files. We also use standard web analytics (Google Analytics, Meta Pixel) to measure general usage, kept separate from those results; see our Privacy Policy.

      Export Pro Tools markers

      Exports true-peak overs (against the selected spec's limit) as a MIDI marker file, plus a sync marker at the file start. In Pro Tools: File ▸ Import ▸ MIDI, destination Clip List, location reference Session Start.

      Set Tempo to match your session's tempo, or enable “Import Tempo Map” on import so Pro Tools adopts this one. Markers are placed relative to the file start, so the sync marker lands at session start — this text only names it, and does not move anything. If your audio doesn't begin at session start, drag the imported markers by that offset.
