Sendspin over Cast

Stream audio to Chromecast and Cast Audio devices using the Sendspin protocol. Enable on-the-fly speaker grouping without Google Home setup, flexible device combinations beyond Google's restrictions (like pairing a Home Mini with a TV), and grouping with other Sendspin-compatible speakers.

Tip: To cast to multiple speakers, open a new tab for each one first, then start casting in each tab.
Enter the full URL to your Sendspin server (e.g., http://192.168.1.100:8927)
Positive delays playback, negative advances it. Changes apply instantly.
FLAC offers good compression with lossless quality. Opus provides better compression but may have compatibility issues on some Cast devices. PCM is uncompressed and uses more bandwidth.
