Where things are adapted to audio-only media such as Radio, Audiobooks, or Audio Plays.
The simplest is the Audiobook, which is usually a simple audio recording of a person reading a particular book. Originally, the audio version was abridged due to the limitations of audio recording media. For instance, a typical book of 100+ pages would have required an impractically large number of vinyl records to play in its entirety, and even the development of the cassette tape with its much longer playtime could require a half-dozen for an abridged edition. However, with the rise of the computer audio file and advances in data storage and playback devices, audio recordings of complete books is now a standard item.
Originally, audiobooks were largely restricted for the visually impaired with the aforementioned recording tech limitations. However, when practical recording media that could be carried on ones' person came on the market, such as the Walkman, the audiobook starting gaining a larger market. Today, audiobooks can be purchased, downloaded and played on smartphones, as well as on other audioplayers or personal computers with considerable convenience. As such, people can listen to literature while multi-tasking other activities with considerable flexibility, which has made the audiobook format a growth market in the otherwise struggling book trade.
Some are full adaptations, usually from Literature, Comic Books, or Manga, giving the then silent characters voices. Others are side-stories for the franchise released in an immerse world of sound, a favorite path for animated fare since, after all, they already have the voice actors and sound effects.
Some particular pitfalls of this kind of adaptation include Narrating the Obvious (where descriptive text is just put directly into the mouth of one of the characters present, making them sound like an interpreter for the blind).
This is especially common in Japan. Since they're pretty cheap to produce (you just need the actors, some sound effects, and mixing equipment to make them), a popular work, be it manga, anime, a Video Game or what have you will often get several "Drama CDs" as spinoffs, pseudo-sequels, prequels and interquels to fill in the world and characters. Since the production values aren't too high and for better franchises the actors can like doing them, you can produce a fair number of them and still make a good profit. However, their all-audio nature makes exporting them a nightmare. Drama CDs are the #1 source of All There in the Manual problems for exported Japanese products; because the form is very uncommon in America, there's no real place to sell them, unionized actors drive costs up, etc. As a result, these basically never leave Japan, which can end up being hugely problematic for fans overseas who are missing parts of the story (and for any producers who care about exporting, since they know it's all but impossible for overseas fans to get that part of the story). On rare occasions, there may be an officially released translation of only the CD's transcript, which is the most fans can expect to get, as was the case for the drama CDs for Final Fantasy XV and The Legend of Heroes: Trails of Cold Steel I and II.
The BBC also produce a fair few of these for broadcast on Radio 4, including some regular features such as "Book at Bedtime" and "Saturday Play."
Contrast with Sound-to-Screen Adaptation, where audio-based works are adapted to visual media.
Examples:
- Lots of manga and anime have audio dramas, from Nadia: The Secret of Blue Water to Count Cain to Gankutsuou. Then there's the "Nyoron Churuya" audio drama. Usually, these only exist in Japanese.
- A great number of manga and Light Novels have Drama CDs released before, during and after their animated adaptations. Sometimes the voice actors between the Drama CD version and the anime version can change. Many a Visual Novel also has a Drama CD included, usually as a bonus. This isn't much of a stretch either, since the line between visual novel and audio adaptation is thin.
- The Sound Stages of Lyrical Nanoha have been an integral part of the franchise from the start, giving additional side-adventures, back-stories, and setting information that would get referenced in the main part of the series, with certain tidbits in the anime only becoming clear if you've listened to these. The biggest one of these is StrikerS Sound Stage X, an entire Story Arc set three years after the third season.
- Slayers has several set between anime seasons:
- Slayers EX (Extra) and Slayers N>EX: Set after the first season and second seasons, there are four stories based off of the prequel Slayers Special novels, but they implement Lina's allies instead of Naga. Naga does appear in N>EX, though.
- The Return of Slayers EX: Five original stories set after seasons 2 and 3, including a run-in with bugs in Saillune's sewer system, meeting baby Val (the reincarnation of the Big Bad of season 3), a hysterical failed attempt to help Zelgadis with his body, and Lina and Naga reminiscing during their old age.
- Slayers Nextra: Set after the second season, a full-scale adventure, unlike the others.
- A prologue and epilogue for the Slayers Premium Non-Serial Movie; the prologue creates an issue in continuity by setting two seasons five years apart, which supposedly isn't true in-universe.
- Two dramas based off of the fourth and fifth seasons of the anime; there is an epilogue story for the one based on Evolution-R.
- A Crossover story starring the Slayers cast and the Sorcerer Stabber Orphen cast.
- Negima! Magister Negi Magi and Negima!? had some drama CDs, which if nothing else, are notable for actually referencing the fandom's popular "KonoSetsu" Portmanteau Couple Name in one of the tracks.
- A more recent one is the Ala Rubra Drama CD
. Specifically the following:
- Breaking Arika out of the prison.
- A Hot Springs Episode where the men of Ala Rubra try to take Eishun's glasses.
- Reenacting the part where Eishun is the Nabe Shogun and Rakan defeats him yet again with the same trick.
- Nagi VS Rakan. From fighting, an endurance race in the hot springs AND bungee jumping.
- THE ENTIRE Ala Rubra ships Nagi and Arika together. Even Rakan gives an example on how to sweet talk Arika to Nagi. Everyone's impressed except for Nagi who just laughs at it.
- A more recent one is the Ala Rubra Drama CD
- Mobile Suit Gundam Wing had a radio play called Blind Target, complete with its own theme songs, which was later adapted into a manga (causing a form of Adaptation Displacement in America).
- Both the manga and anime versions of Chrono Crusade spawned drama CDs. The anime version is particularly notable for being a High School AU and allowing the voice actors from the anime to purposefully make fun of their characters by being as hammy as possible.
- A really notorious example is Getter Robo Armageddon, which was the animation sequel... to a popular, long-running radio drama based on the Getter franchise that 99% of anime fans had never even heard of when Armageddon first made its way to America. Fans end up missing a fair bit of backstory as a result.
- Sound of the Sky has two audio dramas. One which explains the deal with the ghost which kicked off the events of the second episode, only to be forgotten by the end. The other tells of how Filicia and Rio first met, along with an explanation of the history of Helvetia after The Great Off Screen War, at least as far as the characters know.
- Puella Magi Madoka Magica has four Drama CDs - three of which were packaged in the home video releases and one that was released at a convention. The even numbered CDs are probably non-canon since they are light-hearted Slice of Life Self Parodies of the series. However, the odd numbered CDs contain rather important background information including the identity of the cat seen in the anime's Title Sequence and the prior relationship between Mami and Kyoko that was only implied in the anime. (The latter would actually get a Comic-Book Adaptation in a Spin-Off entitled Puella Magi Madoka Magica: The Different Story.)
- Incidentally, an interview with the writer for some of the Drama CDs revealed that originally they would have been a direct continuation of the anime's events.
- Neon Genesis Evangelion has the comedic Self-Parody Evangelion: After the End, featuring the cast as Animated Actors who discusses how to retool the TV show to appeal to a wider audience. Much Conversational Troping occurs, and it is actually surprisingly in-character.
- Pokémon: The Series:
- Pokémon has many Japanese-exclusive radio dramas. For example, The Rocket-dan's Secret Empire is a series of dramas where Musashi (Jessie) and Kojiro (James) act out plays together. In at least one case, their characters were named "Jessie" and "James" in reference to their Dub Name Changes.
- It's a White Tomorrow, Team Rocket!! is an Original Series drama where a Team Rocket delivery trainee named Mondo meets the Team Rocket trio.
- Pokémon: The Birth of Mewtwo was a Japanese-only radio drama backstory to Pokémon: The First Movie. It was later adapted into Mewtwo's Kidroduction for rereleases of the film.
- A Drama CD version of the 2005 film One Stormy Night was released in Japan in 2006.
- Superman has been adapted to radio form many times. The first one gave birth to the popular "It's a bird! It's a plane!" opening, and was responsible for creating kryptonite as well. It was also possibly responsible for killing the KKK.
- Batman likewise has had a few stints, albeit brief, Knightfall being adapted by The BBC.
- Graphic Audio has since joined with DC to bring a number of the company's properties into "Long Car Ride" radio versions, including both original stories, and adaptations of many a Crisis Crossover. The Infinite Crisis one is particularly good.
- Marvel has also joined their ranks. Currently they have the adaptation of Civil War as well as an original novel based on Spider-Man and an upcoming original story based on The Ultimates.
- In the late '70s, there was a short-lived radio show version of Fantastic Four. It reasonably faithfully followed the original comic issues, but is probably best known as a very early role of a pre-Saturday Night Live Bill Murray, playing Johnny Storm.
- The Sandman (2020), a faithful audio drama adaptation of The Sandman (1989), using narration and sound effects in lieu of visuals.
- A BBC Radio 4 adaptation of the Guardian strip Clare In The Community became one of the station's longest-running sitcoms.

produced a number of audio dramatizations of scenes taken from The Wormhole Chronicles, a crossover fanfiction series based on Halo and Mass Effect.
- Gulliver's Travels was given a 30-minute adaptation for radio's Good News of 1940, and was presented with a Framing Device of Gulliver returning to Lilliput to visit his tiny friends. Jessica Dragonette and Lanny Ross, the singing voices of Princess Glory and Prince David respectively, did their singing and speaking voices for the broadcast.
- All three original Star Wars movies had radio play adaptations broadcast by NPR: Star Wars
in 1981, The Empire Strikes Back
in 1983, and Return of the Jedi
in 1996. The first one is very famous for including a whole lot of stuff that ended up on the cutting room floor of the original movie, including early scenes on Alderaan with King Organa, a long chat between Biggs Darklighter and Luke that established both their characters, and a greatly expanded interrogation scene between Vader and Leia.
- As have the following comic book arcs: Tales of the Jedi Knights of the Old Republic, TOTJ Freedon Nadd Rebellion, TOTJ Dark Lords of the Sith, Dark Empire I, II and Empire's End, Crimson Empire, and the three Dark Forces graphic novels. Oddly enough, they never finished them by releasing the two more Tales of the Jedi arcs featuring Ulic Qel-Droma as well as making Crimson Empire II. Dark Empire has some script changes.

If you think King is creepy on the page, wait until you hear Lisa Simpson narrating it!), Joe Mantegna, and Tim Curry.
- Even though the first two books of The Hitchhiker's Guide to the Galaxy Trilogy were originally radio plays (and then adapted to other media), the last four were books first and later adapted for radio.

- An outfit called BBV Productions produced audio plays and series of varying officialness during the Nineties: one starring Colin Baker and Nicola Bryant as "The Stranger" and "Miss Brown"; one starring Lalla Ward and John Leeson as "The Mistress" and "K-9"; and one starring Sylvester McCoy and Sophie Aldred as "The Professor" and "Ace." None of these were licensed Doctor Who spin-offs, though BBV did obtain a license for K-9 directly from the writers who created the character (an approach they also used to have several recognizable monsters appear in their productions). The "Stranger" and "Mistress" series got away with it by having a low profile and just enough differences from the originals, but the "Professor and Ace" series attracted official notice because McCoy and Aldred were basically playing the same characters under the same names ("Professor" was what Ace always called the Doctor in canon, too), and the BBC stepped in to force some more filing-off of serial numbers.
- BBC Audio has produced several audiobooks featuring the Tenth and Eleventh Doctors. They also created three series of Fourth Doctor audio dramas, starring Tom Baker and Richard Franklin (reprising his role as Third Doctor "companion" Mike Yates).
- BBC Radio produced a few audio dramas of Torchwood, that originally aired on BBC Radio 4. The first celebrated the switching on of the Large Hadron Collider. This was followed by one three-episode series of plays to bridge the gap between series 2 and 3, and another, Torchwood: The Lost Files to bridge the gap between 3 and 4.
- BBC Audio made some audiobooks of The Sarah Jane Adventures.
- There have been a few instances of BBC SitComs transferring from TV to radio:
- Dad's Army was successfully adapted for radio, running for four series.
- Steptoe and Son also made the transition from screen to sound.
- One Foot in the Grave was also adapted for radio, but there were only four radio episodes.
- Yes, Minister: sixteen episodes, according to The Other Wiki
.
- Have Gun – Will Travel was one of the few television shows that then had an adaptation for radio, as opposed to the other way around.
- Various adaptation of Kamen Rider, in tapes.
- Radio 4's six part Neverwhere technically belongs under TV, although Neil Gaiman would probably rather you considered it an adaptation of a book.
- The Channel 4 sketch show Absolutely has been revived on BBC Radio 4 as The Absolutely Radio Show.
- There was a brief attempt to adapt I Love Lucy as a radio show – a little ironic considering the concept started as a radio show years earlier – but after a single unaired trial episode was produced (using the same script as the TV episode "Breaking the Lease," fleshed out with descriptive narration from Arnaz as Ricky), the idea was abandoned. However, the radio pilot did have one positive effect: CBS executives had worried that Arnaz's accent was too thick for American audiences to understand. Hearing the radio pilot convinced them that his accent wasn't as thick and undecipherable as they had originally feared.
- Orson Welles became famous with his The Mercury Theatre on the Air, which adapted works of literature, both stage plays like Sherlock Holmes and novels like The Pickwick Papers. His most famous broadcast, and probably the all-time most famous instance of this trope, is the October 30, 1938 broadcast The War of the Worlds, which adapted the novel by H. G. Wells.
- Especially in the 1960s and 70s, a huge number of record albums were recorded for children by studios like Power Records. They adapted everything from classic novels like Melville's Moby-Dick and Barrie's Peter and Wendy, to superhero stories (some adapted from comics, some original) and TV shows like Josie and the Pussycats, to nursery rhymes and fables from Aesop.
- This especially applies to Disney who has made both book and record, and "storyteller" LP versions of not only their own movies, but also the Star Wars trilogy, E.T., and even the first four Star Trek movies. They also adapted the first two Indiana Jones movies.
- Kid Stuff Recordsnote is another notable maker of these. Many of their various licenses include, but are by no means limited to: Barbie, Masters of the Universe, Strawberry Shortcake, the original Transformers series, and even video game licenses like Pac-Man.note
- Realm's catalog includes audiobook adaptations of classic sci fi short stories.
- The Reduced Shakespeare Radio Show, a 6-part series produced by the BBC World Service, is essentially an Adaptation Expansion of The Complete Works of William Shakespeare (Abridged).
- The Moth, a popular New York true storytelling series, did shows for ten years before releasing the audio as a podcast and then the NPR show The Moth Radio Hour.
- The Legend of Heroes: Trails in the Sky has a whole bunch of these, focusing on various characters and expanding on them. Even with the games coming to America at last, we're quite unlikely to see these.

Even when the first two were in print, it was a nightmare trying to buy them, as none of the Japanese vendors selling them shipped overseas. Luckily for (Japanese-speaking) fans, the third didn't have this problem.

- The Freddi Fish series had a book titled Sing Along with Freddi Fish and her Friends, which came with an audio cassette of the same name.
- The Mega Man Zero series had audio tracks included on each of its soundtrack releases. The story importance of these tracks ranged from trivial (such as how Alouette came up with the names for the Baby Elves) to vital, such as explaining Elpizo's backstory (including how he got his name), how Phantom knew about Omega's true nature, or why the Guardians chose to help Zero at the end of the third game.
- The Japanese version of Elemental Gearbolt includes an unlockable audio drama version of an event mentioned in-game, in which the main characters meet as children and promise to reunite. It was Dummied Out of the English release, but the localizer summarized the story in the manual.
- Fire Emblem: Awakening has four CD dramas, each with different stories. The first one (with a male Avatar) depicts the days around Chrom's marriage and focuses on character interactions and some ambushes by Risen. The second (with a Female Avatar) revolves around someone's serious Sick Episode and the aftermath of Emmeryn's Heroic Suicide, alongside Henry and Lucina/"Marth"'s sort-of Teeth-Clenched Teamwork. The third (no defined Avatar) is all about the already Bad Future that Lucina and her fellow Second Generation characters are about to leave. The fourth and last one (also w/o a defined Avatar) is noticeably Lighter and Softer and about Lucina and the children's struggle to find Lucina's precious tiara and both Morgans incidentally meeting up with each other in the Outrealms.
- There are many CD Dramas for for The King of Fighters, usually one or two per game, with individual characters sometimes getting their own CDs. They go from very cracky skits
bordering on Gag Dubs, to pretty
interesting
characterization-wise
(i.e. Dengeki Bunko explains how both the Japan Team and the Women's Team came to be among other things, The Sun and The Moon chronicles Iori Yagami's life outside KOF and the Yagami/Kusanagi feud at an unspecified time in the past, and KOF 2000 gives more background on K' and his group while also featuring Athena's misadventures through the world until she finds Kyo and they have a more serious talk about how everyone misses him at home).

Notable anomalies include the omission of Sundae and the McNuggets, Franklin and Tika being replaced with a different set of kids and Grimace, Hamburglar and Birdie being respectively voiced by Frank Welker, Carl W. Wolfe and Russi Taylor (their standard voice actors in the McDonaldland ads at the time) rather than Kevin Michael Richardson, Charlie Adler and Christine Cavanaugh.
