What true-peak and loudness limits do Netflix's public sound specifications state for a Music and Effects (M&E) mix?

In the Netflix Sound Mix Specifications v1.6 (archived 9 Aug 2026), the 5.1 M&E section states no numeric peak or loudness value of its own; M&E peak compliance is by reference to the Netflix Peak specification, -2.3 dBFS limiter settings are recommendations, and the theatrical 0 dB true-peak allowance belongs to a different deliverable. Curator qualifications: M&E guideline page (S5) and the -24 LKFS fallback/Best Practices search (E5, E6, E8) not re-read verbatim. Whether QC applies -2 dBTP to M&E files is not stated (producer synthesis). Archived page text only (gzip-decoded where stored compressed); no audio measured. Limitations: Archived snapshot. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
