If you run a dual PC setup, Wave Cast is built for you.
We designed it to send game audio from your gaming PC to your streaming PC using Ethernet or Wi-Fi. That way, you can keep everything connected to your gaming setup, including your headphones, while managing your stream, voice, and apps on the other side. Audio goes one way at a time, but you can swap directions when needed.
Key features
- Low-latency audio: Delivers audio with minimal delay between PCs
- One-click pairing: Detects your other PC and connects automatically
- Flexible routing: Send all audio, the current app, or something specific
- Output control: Choose any output device or virtual channel on the second PC
- Control from either PC: Pick apps and outputs from either side without switching machines
- Custom network settings: Pick your adapter and adjust latency to match your setup
What’s coming next
These features are already in the works for after the beta:
- Mic return for voice chat on the gaming PC
- Route different apps to different outputs on the streaming PC
- Stream Deck integration
How to get started
- Install Wave Cast on both PCs
- Open the app and enter the unlock code on one PC: WaveCastBeta2025
