Version 2026.44 adds a rolling buffer for supported MP3/AAC stations. You can jump back 30 seconds to catch something you missed. Enable Pause live radio under Settings → Automation to use it.

You can also open the player in its own resizable window. An optional loudness setting turns louder stations down during local playback.

Install it through Add Widgets → Get New Widgets → search “On Air”.

If you try it on EndeavourOS, I’d appreciate feedback on the buffer and window mode. Please include your Plasma version and the station name if something goes wrong.
