Roughly a year ago I started to look into whether I could use PipeWire/WirePlumber to easily mix my chat and game audio, while in-game. I’ve seen this feature on gaming-oriented headsets and DACs before. I looked into several of the fantastic suggestions from that thread, but they weren’t quite what I wanted. I messed around with a script, and that largely would have worked, but several months ago I decided to make it into something more user-friendly, and here we are.
https://github.com/arulan/bridge
Bridge creates two virtual outputs, Aux and Main, and at its center sits the crossfade mixer. Route your audio to the separate outputs and adjust the mix between them from anywhere.
- Create Routing Rules to automatically send app audio to your desired output
- Conveniently setup headphone virtual surround by providing your own HeSuVi HRIR file
- Create output presets and switch between them at the press of a button
- Global Shortcuts support, control your audio from anywhere
This means you for example you can send Discord to Aux, and let your game default to Main, and adjust the balance of the two while in-game via your set Global Shortcut. If you have a hardware knob, you can bind it to that too. Route any app’s audio to any output and save it as a rule. Setup presets (your desktop DAC for headphones, and your HDMI output + wireless BT headset for the living room) and swap between them with a shortcut. Setup HeSuVi virtual surround for headphones by just providing a HRIR .wav file.
The 0.5.0 release is its initial beta release, so please keep that in mind, but I’d appreciate any feedback or issues raised while using it. It’s available as a flatpak bundle on the release assets.
Don’t mind the app icon. Until I can set aside some time to learn Inkscape and/or get some help, that’ll have to wait. If you’d like to offer your services, please feel free to reach out.
Not vibe coded.
PipeWire is very powerful, but accessing its most advanced features is often not very user-friendly, and that’s part of what I’m hoping Bridge can provide. I have plans for additional features that I hope to implement this year, but please feel free to suggest any that you think would fit well.
