What are the 3 Types of Podcasts? 

The three types of podcasts are interview podcasts, storytelling podcasts and solo podcasts. 

Let’s dive into the three types of podcasts you can find online:


The first type of podcast is the interview or conversation-based podcast. This type of podcast typically features one or more hosts interviewing guests on a wide range of topics. 

These podcasts often feature experts or thought leaders in various fields, providing listeners with unique insights and perspectives. 

The conversational format also allows for an engaging and dynamic exchange of ideas and information.


The second type of podcast is the storytelling or narrative-based podcast. 

These podcasts are typically produced with a high level of production value and often feature a series of episodes that tell a story or explore a theme. 

A storytelling  podcast can be highly engaging and immersive, with podcast creators drawing listeners in with compelling characters, plot twists, and cliffhangers.


The third type of podcast is the solo or monologue-based podcast. 

This type of podcast typically features one host who speaks directly to the audience on a wide range of topics. 

Monologue-based podcasts can be highly informative and personal, providing listeners with valuable insights and perspectives from the host’s own experiences and expertise.

Is a Podcast Different from an Audio File? 

To start, it’s important to understand that a podcast is actually a type of audio file. However, not all audio files are podcasts. 

An audio file is simply a digital recording of audio, such as a song, a speech, or a sound effect. It can be saved in a variety of formats, such as MP3 or WAV, and can be played on a variety of devices, such as a computer or a smartphone.

A podcast, on the other hand, is a specific type of audio file that is distributed through a feed, allowing listeners to subscribe and receive new episodes automatically. 

Podcasts are typically produced in a series, with episodes released on a regular schedule. They often feature a specific theme or topic, and may include interviews, discussions, or storytelling.

So, while both audio files and podcasts are digital recordings of audio, the key difference is in how they are distributed and consumed.

Are Podcasts Audio or Video?

Podcasts are primarily audio-based, offering listeners a convenient way to consume content while on the go, whether during commutes, workouts, or leisurely moments. While some podcasts may include video elements, such as recordings of live events or interviews, the vast majority of podcasts remain focused on delivering engaging audio experiences. 

However, in response to the evolving digital landscape, some podcasters have embraced the multimedia approach, incorporating video elements into their shows. 

The multimedia approach includes recording interviews on video and sharing them on platforms like YouTube, enhancing the reach and accessibility of their content to cater to diverse audience preferences.

Difference Between Podcast and Podcast Episode

PodcastPodcast Episode
A series of audio (and sometimes video) episodes that are released on a regular basis, often with a specific theme or topic.A single installment of a series, released as part of the ongoing podcast.
These episodes can be downloaded or streamed from various podcast platforms and apps, and are typically part of a larger series of content.Each episode may feature a different topic, guest, or format, but is part of the larger series and can be listened to in sequence with other episodes.

So, while a podcast is a collection of episodes, each episode is a standalone piece of content that can be listened to on its own or as part of the larger series.

It’s worth noting that while most podcasts are released in an episodic format, some may be released as a single, standalone piece of content. 

In this case, the term “podcast” may refer to the single piece of content rather than a larger series of episodes.
