Podcasting with Micro.blog

April 12, 2018

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.

To upload an MP3 on the web, under “New Post” click the audio button to select a file:

MP3s should be 35 MB or less. The following list shows an estimate for how long episodes can be depending on the audio encoding:

  • 64 kbps: 74 minutes
  • 96 kbps: 49 minutes
  • 112 kbps: 42 minutes
  • 128 kbps: 36 minutes (used in Wavelength)
  • 192 kbps: 23 minutes

Micro.blog uses your profile photo for the cover artwork. If you haven’t uploaded a custom profile photo recently, add one under Account on the web. Micro.blog will save a high-resolution version (1400x1400) to use with podcast clients.

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.
