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. Stereo remains untested until the analysis adds stereo fixtures, stereo render capture, and stereo offline measurement.
