Netflix Dolby Atmos Home Mix Deliverable Requirements v1.9


The Dolby Atmos Home Mix must meet the following requirements:

  • At a minimum, must be mixed in a 7.1.4 room.
  • This is a nearfield mix. The most common monitoring levels for nearfield are 79db or 82db.
  • Must conform to Netflix loudness spec (-27db LKFS +/- 2 LU 1770-1 dialog-gated).
  • Peaks must not exceed -2dbfs True Peak. To achieve this, we recommend setting True Peak limiters on all beds and objects at -2.3 or lower. Loudness and peaks may be measured via a 5.1 rerender.
  • For native Atmos mixes, make sure the 5.1 and 2.0 rerenders are approved as well. Please see Netflix Original Delivery Specifications v3.1 or Netflix Audio Mix Specifications and Best Practices v1.0.
  • All beds and objects are encoded and will always be audible. A printmaster may utilize a composite of all bed material OR multiple beds, but not both.
  • If a 85 db reference theatrical mix is created, two complete sets of deliverables are required. One for theatrical, one for nearfield.
  • All deliverables shall be conformed and synced to final IMF picture as long-play and not separate reels. Leader and sync pop shall be removed. File must start at FFOA.
