Here is a review of what you can expect from the software and how the trial version works.

To remove this, you must purchase a license key (typically around $29). Pros & Cons Incredibly easy "pick a source, pick a speaker" UI The trial limitation (static) is quite jarring Works with non-AirPlay hardware (Chromecast, Sonos) Higher price point for a single-utility tool Rock-solid sync with zero lag Requires a background "ACE" installation for audio capture Is It Worth It?

If you have a "mixed" household with different speaker brands (an old Apple TV, a new Sonos, and a Bluetooth speaker), is the only reliable way to make them work as a single unified system. However, if you only use Apple devices, macOS’s built-in AirPlay 2 features might already do enough for you for free.

After 10 minutes of streaming, Airfoil will begin to overlay loud noise (static) over the audio.

Unlike standard AirPlay, which is often limited to specific apps, Airfoil can grab audio from any software running on your Mac.
