Here’s what the dev team had to say in response to your question:
below are instructions for getting info on custom feeds (aka podcast channels)
$General = powerpress_get_settings(‘powerpress_general’); (basically just get_option(‘powerpress_general’), but if powerpress is active on the site, powerpress functions should be available for use)
$General[‘custom_feeds’] is an associative array where keys are feed slugs and values are feed titles
To get all feed-level settings for one channel, powerpress_get_settings(‘powerpress_feed_{slug}’);
this should be enough to get them on the right track with whatever they’re doing. This is how they can access the information they want, and it’s up to them to organize that into an array.
