Podcast Delivery Targets

This automated scenario validates a -19 LUFS mono playback-equivalent working target, not a universal platform acceptance rule. Apple currently recommends audio around -16 LKFS (+/-1) and true peak no higher than -1 dBFS without publishing a separate mono target. AES TD1008 documents the 3 LU change that can occur when mono is duplicated to two channels and recommends correct channel metadata or player compensation. The separate stereo scenario validates genuine two-channel processing against Apple's published recommendation.

Profile	Channels	Integrated Loudness	True Peak Ceiling	Coverage	Basis
Apple Podcasts recommendation	Stereo	-16 LUFS	-1 dBTP	Not tested in this run	Around -16 LKFS (+/-1) and true peak no higher than -1 dBFS
Mono playback-equivalent convention	Mono	-19 LUFS	-1 dBTP	Tested in this run	Working target for raw mono files expected to be duplicated to stereo playback

Project	Status	Result
Leveler	PASS	Validates complete-program Podcast Episode delivery after Learn and lock; isolated renders remain diagnostics.
Meter	PASS	Checks the Leveler program delivery and isolated diagnostics with the proposed monitoring view.
Optimizer	PASS	Exports Podcast Episode delivery candidates from source fixtures.
Limiter	PASS	Renders Podcast Episode candidates through the loudness and true-peak limiters.
Compressor	PASS	Checks complete-program Podcast Episode delivery after source-to-target compression; isolated renders remain diagnostics.
