What Is a Podcast RSS Feed, and How Do Podcasts Work?

A podcast RSS feed is a single public file, written in a standard format called RSS, that describes a show and lists its episodes, each with a link to its audio file. Podcast apps check that file, notice when a new episode appears and fetch it for the people who follow the show. The feed is why one podcast can turn up in many apps at once without the creator uploading it to each of them.

That's the short answer. Before opening up a feed, it helps to pin down what counts as a podcast and how it compares with radio and audiobooks.

What is a podcast?

Merriam-Webster defines a podcast as "a program (as of music or talk) made available in digital format for automatic download over the Internet."

The word that matters there is automatic. A single audio file on a website is just a recording. What makes something a podcast in the traditional sense is that it comes out as a series people can follow, with new episodes arriving on their own.

In everyday speech the word has stretched. People call video shows podcasts, and companies call internal audio updates podcasts even when they're only shared as a link in an email. Those uses are common and understood. In this article, though, "podcast" means a series distributed through a feed.

How is a podcast different from radio or an audiobook?

The lines can blur. A station can publish its shows as a podcast, and an author can release a story in installments. The table describes the typical case.

What is inside a podcast RSS feed?

RSS is an XML format. Podcasts use RSS 2.0, whose specification is maintained by the RSS Advisory Board. A feed has two layers.

The show (channel). Title, description, link, language and image. This is roughly what you see on a show's main page in an app.

The episodes (items). Each episode is an item with its own title, description and publication date. The part that turns an item into a playable episode is the enclosure, an element that points to the media file. The specification gives it three required attributes: the file's URL, its length in bytes and its media type (audio/mpeg for an MP3).

Most podcast feeds also give each item a guid, which the specification describes as a string that uniquely identifies the item. Keep it stable and apps can recognise an episode they have already shown, even after its title changes. Change it by accident and followers may see an old episode come back as new.

A stripped-down item looks roughly like this:

<item>
  <title>Episode 12: Watering in a heat wave</title>
  <guid isPermaLink="false">garden-show-ep-12</guid>
  <pubDate>Sat, 31 Oct 2026 08:00:00 GMT</pubDate>
  <enclosure url="https://example.com/audio/ep12.mp3"
             length="18400000" type="audio/mpeg" />
</item>

Individual directories may ask for extra show-level fields, such as a category or cover art, and usually check a feed before accepting it. Their own documentation lists what they expect.

How does an episode get from a feed to someone's phone?

1. You upload an audio file to a podcast host, a service that stores the file and generates the feed.
2. The host adds a new item to your feed, with the enclosure pointing to that file.
3. Podcast directories, the catalogs inside podcast apps, check your feed and pick up the new item. You submit the feed address to each directory only once.
4. People who follow the show get the episode in their app, often downloaded in the background.

Many apps also let a listener paste a feed address directly and follow a show that way, without going through a catalog.

Do you need an RSS feed?

Only if you want your show in podcast apps. If your audience is your team, your customers or a class, the audio file itself or a link that opens in a browser can do the job. Plenty of internal and educational audio works that way.

If you do want to be in the apps, a podcast host handles the feed for you. You rarely need to write XML by hand.

Where do people listen?

• Podcast apps on phones and computers, where you follow a show and get new episodes.
• Audio streaming apps that include a podcast section.
• Web pages with an embedded player.
• Direct links sent in a chat or an email, which open the episode in a browser.
• Smart speakers and car systems that support podcast apps.

Because RSS is an open format, any app that reads it can play the show.

Podcast glossary: which terms should you know?

• Episode: one installment of a show, with its own audio file.
• Feed / RSS feed: the file describing a show and its episodes, read by podcast apps.
• Enclosure: the part of an episode's entry that links to the audio file, with its size and type.
• GUID: a permanent unique ID for an episode.
• Host (hosting provider): the service that stores audio files and publishes the feed.
• Directory: the catalog of a podcast app, where a show appears once its feed is submitted.
• Follow (subscribe): telling an app to fetch new episodes from a show automatically.
• Embedded player: a small player placed on a web page so visitors can listen without an app.

Where does Fynqcast fit?

Fynqcast creates the episode itself, starting from text. On the website you describe a topic or paste your notes into the text field, pick the language, length and tone, and choose one voice or two voices in conversation. The AI drafts a script that you can read through and edit line by line; if it isn't right, you can generate a new one with different settings. The audio is produced only after that.

Once the episode is ready, you can download it as MP3, WAV or M4A, copy a link to a listening page that anyone with the link can open, or send it straight to WhatsApp or Telegram. Fynqcast does not publish episodes to podcast apps, and the website does not generate an RSS feed. If you want your show in directories, you upload the downloaded file to the podcast host of your choice, which takes care of the feed.

What each plan includes is set out on the pricing page.
