Micro.blog offers an optional paid plan that lets you create a short-form podcast hosted directly on Micro.blog. You can upload an MP3 for your microcast from the web, or use the companion iPhone app Wavelength to record, edit, and publish a new episode.
Hosted microcasts use a separate RSS feed for your episodes: yourdomain.com/podcast.xml. You can add this feed to apps like Overcast or Castro, or register it with the Apple Podcast Directory. Just like a regular microblog, you can also use a custom domain for your site. (There is also a JSON Feed version at yourdomain.com/podcast.json.)
To upload an MP3 on the web, under “New Post” click the audio button to select a file:
Unlike short microblog posts which don’t need a title, podcast episodes are best with a title so that they show up in other podcast apps. Click “Posts” on the web to edit existing episodes to add a title.
MP3s should be 75 MB or less. The following list shows an estimate for how long episodes can be depending on the audio encoding:
- 64 kbps: 110 minutes
- 128 kbps: 80 minutes (used in Wavelength)
- 192 kbps: 50 minutes
Micro.blog uses your profile photo as the cover artwork. If you haven’t uploaded a custom photo recently, you can add one from the Account page on the web. Micro.blog will store a high-resolution version (1,400 × 1,400) for use in podcast apps. If you prefer to use separate cover art instead of your profile photo, you can set that up on the Blog Settings page.
By default, microcasts are set to the iTunes category “Society & Culture - Personal Journals”. You can select a different category from the list under Pages → “Edit Domain & Design”. When you register your podcast with Apple, it uses this category for the podcast directory.
