Audio podcasts are best imo. CastGarden supports both though.

Just create the best quality mp3 you can, upload it to your favorite web2 host and CastGarden will auto-import it from there and syndicate it out to the fediverse, hive chain, and open RSS. Totally automated.

It would be great to have Spanish podcasts on CastGarden :)
