ToneRelay and Airfoil for Windows Alternative Scope
ToneRelay is an independent app for a narrow Windows-to-HomePod use case. It is not a broad replacement claim.
ToneRelay fits when
- You use Windows 10 or Windows 11.
- You want one HomePod or HomePod mini as the speaker.
- You only need Windows default output audio.
- You want a local trial without an account.
Not a broad replacement claim
- Works with one HomePod or one HomePod mini at a time.
- Uses the current Windows default output, not separate per-app routing.
- Best for everyday listening, not timing-critical gaming or live monitoring.
- Does not add Sonos, Chromecast, DLNA, Apple TV, multi-room, or stereo-pair support.
