An Enhanced podcast also known as a slidecast is a type of podcast that combines audio with a slide show or diaporama 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, such as PowerPoint, 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." IGI Global defines an enhanced podcast as "audio synchronized with either static instructional content (e.g., Powerpoint™) or with very minimal motion for short spans of time." The alternative term "slidecast" is a portmanteau of slide show and podcast, which has been used in software such as SlideShare and Creator Studios.
The phrase "enhanced podcast" naturally gained prominence when describing how a podcast with additional features differed from a regular audio podcast. For instance, Penn State News described a podcast that used visuals by calling it an "image-enhanced podcast," and NiemanLab has described the integration of images and video into a podcast as an "enhanced podcast experience."
iTunes developed a feature called "Audio Hyperlinking" that they patented in 2012. Ben Drawbaugh of Engadget, reviewed the Apple TV and lamented that enhanced podcasts are not properly supported by the home entertainment system.
The Creator Studios extension made by Digital Inspiration allows Google Slides users to sync YouTube videos with their slides.

SlideBoom provided features to have audio and video recordings of presentations.

The Times of Indonesia distinguished enhanced podcasts from other podcasts by its use of images.
Slidecasting may be useful for the display of relevant photographs or text, and are an alternative to camera video recordings.
Like other podcast derivatives, slidecasts are syndicated through RSS. Because of the visual dependency, slidecasts are usually distributed in video formats, such as .flv or .mov, similarly to video podcasts, but HTML5 now makes it possible for slidecasts to be distributed in straight HTML, making them compatible with iPhone and iPad devices. Slidecasts may also be embedded into webpages and textual blog articles in a similar fashion to web-based videos
Enhanced podcasts are sometimes used by businesses to convey business models, marketing strategies, and company news. After the Kraft Heinz merger, the company produced an enhanced podcast to demonstrate the progress that had been made and to clarify the company's intentions and goals for the future. Inside HPC hosted a slidecast entitled Radio HPC: The Rich Report, which discussed technology and business news.
Enhanced podcasts are used for educational purposes as a substitute for an in-person lecture or as a supplement to a lesson. Professors occasionally have their students create their own enhanced podcast as a school project. For instance, Laura Guertin, a professor at Pennsylvania State University, had her students create an enhanced podcast that identified various species of trees at the Ridley Creek State Park.
Enhanced podcasts have been used for news and talk show purposes. For instance, American Public Media produced an enhanced podcast called Weekend America hosted by John Moe.
