What can I play through presets?

Only DRM free content. Probably not what you want your fancy internet connected speaker to play.

What is DRM free content?

Everything you can get a direct file link to. It needs to be without a login, hosted on the internet or your local network.

This excludes most streaming services like Netflix or Spotify, since you cannot get a direct link (.mp3/4) and have to log in.

However most radio stations have direct links and don't need a login.

What formats are supported?

Almost every major format is supported. A full list is available by Google.

How do I create presets?

Use the preset generator. A guide is available.
