Hi Product Hunt! I'm Hifumi, the developer of SoundFerry.
Want your Mac's music playing in the kitchen and living room, not just at your desk? SoundFerry sends Mac audio to multiple AirPlay 2 and Chromecast speakers, including both types together.
Keep using Spotify, internet radio in your browser, or your usual music app. Save your favorite speaker combinations as groups, adjust timing for individual speakers, and fine-tune the sound with EQ.
SoundFerry costs $19 once, with no subscription and all future updates included. The 7-day free trial doesn't require a payment card, so you can test your own speaker combination before buying.
It runs on Apple silicon Macs with macOS 14 or later. Your speakers need to be on the same network, and setup requires an audio driver and a restart.
One thing to know: this is built for music listening, not low-latency monitoring. Playback has a few seconds of delay, and timing depends on your speakers and network. Video may need audio-delay compensation.

What speakers would you like to use together? I'd love to hear about your setup and how the trial works for you.
