PurposePresets - Deezer Stereo Reference - Optimizer - Summary

Deezer Target Reference

Basis: Legacy working reference.

Deezer has historically described a -15 LUFS normalization target, but it is not a current public delivery requirement. These checks validate the APU product recipes on deterministic stereo material; they do not certify platform or broadcaster acceptance.

Optimizer export candidates passed. The checked rows are inside the Deezer legacy reference Integrated LUFS window and peak ceilings.
