Wave Cast

Dual PC audio at your fingertips. With the Wave Cast plugin, control your connection and route application audio directly from Stream Deck — no more switching windows to manage your dual PC setup. Wave Cast connects two Windows PCs over your network for low-latency audio streaming. Whether you're running a dual PC stream, capturing gameplay, or sharing a mic between machines, it handles the hard part so you don't have to. This plugin puts the controls right at your fingertips. Actions include:

Connection State: Monitor your connection quality and toggle it on or off with a key press. Color-coded signal indicators show stability at a glance — green for solid, yellow for okay, orange for trouble — with optional latency readout in milliseconds.

Select Application Audio: Choose which app audio gets sent through Wave Cast. Pick from local or remote applications, see what's selected and what's live, and switch sources on the fly. On Stream Deck +, rotate the dial to browse available audio apps in a carousel view, then press to select.

Featuring real-time status displays. Connection quality, latency, and app selection update on your keys so you always know what's happening — without leaving your game or stream. Feeling creative? Try adding Wave Cast to a multi action sequence! Multi actions combine actions from different plugins for special effects. Need an example? Connect your PCs, switch an OBS scene, and select your game audio — all with a single key press. Stream more, troubleshoot less. Get the official Wave Cast plugin by Elgato.

Requires Wave Cast 1.2 or later on both PCs.
