Aggregator for Audio-Rss Feeds

Hello, I am looking for a WordPress theme that can act as an aggregator for multiple audio rss-feeds.

Something like this: https://themeforest.net/item/podcaster-multimedia-wordpress-theme/full_screen_preview/6804946?ref=Themestation

But with ability to publish posts automatically when an RSS feed is updated, with the opportunity for visitors to play the audio file directly on the page. As well as support to list podcasts in several different categories.
