How to publish your own podcast
The Grand Cast’s production stack is fully open source. It is recorded on a 5+ year old laptop running Linux Mint (https://www.linuxmint.com/).
There are two USB microphones used, a Blue Snowball and a Blue Snowball Ice.
The initial recording is done using OBS (Open Broadcaster Software https://obsproject.com/). There’s almost certainly a better way to do this, but this is the way I’m comfortable doing it, and it ain’t broke so..
The intro and outro are added on, background noise is reduced, and the final mp3 form is generated using Audacity (http://www.audacityteam.org/).
The podcast feed and a few other features are provided through the free WordPress plugin PowerPress (https://create.blubrry.com/resources/powerpress/).
Files are ferried around using Filezilla (https://filezilla-project.org/).
The website domain and hosting is through NameCheap (https://www.namecheap.com/).
Where to submit your podcast
Make sure that you download the corresponding app yourself to make sure it looks correct and updates properly.
iTunes – this is the most important one. A lot of 3rd party apps pull their podcast feeds from iTunes, so getting on here will make your podcast available in many places. https://itunespartner.apple.com/podcasts/
Google Play – https://play.google.com/music/podcasts/publish
Overcast – From their FAQ: “To add a podcast to the directory search, add its URL manually to an Overcast account. If it’s also in iTunes, it will show up within a day.”
