Most of the content linked below is free, but I highly recommend lending financial support if you are able to help pay authors and cover costs.
The District of Wonders – Podcasts
I’m currently the submissions editor over at Tales to Terrify, so I’m certainly biased, but along with StarShipSofa for sci-fi and Far Fetched Fables for fantasy, we air some great speculative fiction stories on our audio magazines for free. We also have some great nonfiction on the podcasts as well.
We are currently all volunteers–authors, narrators, editors and other contributors–but our next Patreon goal will help us begin to pay our authors.
Escape Artists – Podcasts & Magazine
I’d like to credit Escape Pod with getting me into podcasts and reigniting my love of speculative fiction. They have provided so many good stories for so many years for free, and I could not recommend them more. Escape Pod posts the texts of the stories on their website, but Pseudopod and Podcastle are only available in audio.
