You no longer have to be one of the privileged few to record Twitter Spaces. Twitter has announced that all Android and iOS users can record Spaces when they’re hosting. As before, you just have to toggle “record space” before you start. From there, your audio will be available for public listening and sharing 30 days after the initial stream.
Hosts can delete recordings at any time. Twitter will keep audio files for up to 120 days, however, to verify terms of service violation reports.
