Apple Podcasts offers an integrated user experience
with a single show page for everyone,
subscribers and free listeners.
Giving subscribers access to an ad-free episode
from your back catalog is simple.
If you've set up your show by providing your RSS feed,
we have already ingested your episodes and episode details into your account.
To add back catalog audio,
from the episodes tab,
choose a published episode.
Next, under the episode detail page,
add the subscriber audio directly to the episode record.
By linking your subscriber audio,
subscribers will get premium versions
of the same episodes delivered in your RSS feed.
And there will be no duplicate episodes in your feed in the Apple Podcasts app.
