Frequently asked questions
Do listeners need an account or app to join?
No. Listeners just click your room link on any device (iOS, Android, macOS, Windows, Linux) and immediately hear the audio in sync without creating an account.
How does real-time synchronization work?
The host controls playback (play, pause, seek, track changes). The room state is coordinated in Edge RAM with sub-15ms latency, automatically aligning listener audio clocks with continuous drift correction.
What audio formats are supported?
Resonia supports MP3, WAV, FLAC, M4A, AAC, and OGG files. MP3s upload directly, while raw audio files are optimized in the browser for smooth multi-listener streaming.
What is the difference between Community Free and Pro?
Free rooms provide 1 active room, 10 listeners, 1 GB storage, and 24-hour expiration. Pro hosts unlock up to 5 active rooms, 100 listeners per room, 5 GB storage, custom vanity URLs, and 24/7 permanent rooms.
What payment methods are supported for Pro upgrades?
