My brain starts to die when I try to read a journal article,” says Jessica Sacher, a microbiologist at Stanford University in California. Papers are written to be technically comprehensive rather than understandable, she says. “I just want someone to tell me what the gist is.”Now, artificial intelligence (AI) chatbots can help to turn difficult concepts into clear, engaging podcasts, providing a simpler method for keeping up with the literature. Now, Sacher regularly absorbs the latest research by tuning in to AI-made conversations…..Continue reading…

A podcast generator maintains a central list of the files on a server as a web feed that one can access through the Internet. The listener or viewer uses special client application software on a computer or media player, known as a podcast client, which accesses this web feed, checks it for updates, and downloads any new files in the series. This process can be automated to download new files automatically, so it may seem to listeners as though podcasters broadcast or “push” new episodes to them.
Podcast files can be stored locally on the user’s device, or streamed directly. There are several different mobile applications that allow people to follow and listen to podcasts. Many of these applications allow users to download podcasts or stream them on demand. Most podcast players or applications allow listeners to skip around the podcast and to control the playback speed. Much podcast listening occurs during commuting; because of restrictions on travel during the COVID-19 pandemic, the number of unique listeners in the US decreased by 15% in the last three weeks of March 2020.
Podcasting has been considered a converged medium (a medium that brings together audio, the web and portable media players), as well as a disruptive technology that has caused some individuals in radio broadcasting to reconsider established practices and preconceptions about audiences, consumption, production and distribution. Podcasts can be produced at little to no cost and are usually disseminated free-of-charge, which sets this medium apart from the traditional 20th-century model of “gate-kept” media and their production tools.
Podcasters can, however, still monetize their podcasts by allowing companies to purchase ad time. They can also garner support from listeners through crowdfunding websites like Patreon, which provide special extras and content to listeners for a fee. Podcasts vary in style, format, and topical content. Podcasts are partially patterned on previous media genres but depart from them systematically in certain computationally observable stylistic respects. The conventions and constraints which govern that variation are emerging and vary over time and markets; podcast listeners have various preferences of styles but conventions to address them and communicate about them are still unformed.
Some current examples of types of podcasts are given below. This list is likely to change as new types of content, new technology to consume podcasts, and new use cases emerge. An enhanced podcast, also known as a slidecast, is a type of podcast that combines audio with a slide show presentation. It is similar to a video podcast in that it combines dynamically generated imagery with audio synchronization, but it is different in that it uses presentation software to create the imagery and the sequence of display separately from the time of the original audio podcast recording.
The Free Dictionary, YourDictionary, and PC Magazine define an enhanced podcast as “an electronic slide show delivered as a podcast”. Enhanced podcasts are podcasts that incorporate graphics and chapters. iTunes developed an enhanced podcast feature called “Audio Hyperlinking” that they patented in 2012. Enhanced podcasts can be used by businesses or in education. Enhanced podcasts can be created using QuickTime AAC or Windows Media files. Enhanced podcasts were first used in 2006.
A fiction podcast (also referred to as a “scripted podcast” or “audio drama”) is similar to a radio drama, but in podcast form. They deliver a fictional story, usually told over multiple episodes and seasons, using multiple voice actors, dialogue, sound effects, and music to enrich the story. Fiction podcasts have attracted a number of well-known actors as voice talents, including Demi Moore and Matthew McConaughey as well as from content producers like Netflix, Spotify, Marvel Comics, and DC Comics. Unlike other genres, downloads of fiction podcasts increased by 19% early in the COVID-19 pandemic.
A podcast novel (also known as a “serialized audiobook” or “podcast audiobook”) is a literary form that combines the concepts of a podcast and an audiobook. Like a traditional novel, a podcast novel is a work of literary fiction; however, it is recorded into episodes that are delivered online over a period of time. The episodes may be delivered automatically via RSS or through a website, blog, or other syndication method. Episodes can be released on a regular schedule, e.g., once a week, or irregularly as each episode is completed.
In the same manner as audiobooks, some podcast novels are elaborately narrated with sound effects and separate voice actors for each character, similar to a radio play or scripted podcast, but many have a single narrator and few or no sound effects. Some podcast novelists give away a free podcast version of their book as a form of promotion. On occasion such novelists have secured publishing contracts to have their novels printed. Podcast novelists have commented that podcasting their novels lets them build audiences even if they cannot get a publisher to buy their books.
These audiences then make it easier to secure a printing deal with a publisher at a later date. These podcast novelists also claim the exposure that releasing a free podcast gains them makes up for the fact that they are giving away their work for free. A video podcast is a podcast that features video content. Web television series are often distributed as video podcasts. Dead End Days, a serialized dark comedy about zombies released from October 31, 2003, through 2004, is commonly believed to be the first video podcast.
A number of podcasts are recorded either in total or for specific episodes in front of a live audience. Ticket sales allow the podcasters an additional way of monetizing. Some podcasts create specific live shows to tour which are not necessarily included on the podcast feed. Events including the London Podcast Festival, SF Sketchfest and others regularly give a platform for podcasters to perform live to audiences.
Podcast episodes are widely stored and encoded in the mp3 digital audio format and then hosted on dedicated or shared webserver space. Syndication of podcasts’ episodes across various websites and platforms is based on RSS feeds, an XML-formatted file citing information about the episode and the podcast itself.
