WaveMix

An audio mixer for streamers on Linux. Put your apps in channels, give each one a volume for you and a volume for your stream, and run your mic through its own filters, all in one window. OBS records the mixes and the mic as ordinary audio devices.

Features

• Two sliders per channel – Personal (what you hear) and Stream (what your stream hears).
• Channels for your apps – Game, Voice, Music and more; tick an app once and it goes back there every time.
• A mic with real filters – noise removal, EQ, compressor, gate and more, in any order, tuned live.
• A separate VOD mix – leave copyrighted music out of your VOD track and keep it on stream.
• Channel meters – see at a glance whether sound is reaching each channel and your mic.
• Made for OBS – one device for your stream, one for your mic, ready from the moment you log in.
• Themes – Dark, Light, Midnight and High Contrast, or style it yourself with CSS.

Development status

WaveMix is in alpha. It's usable, but expect bugs and changes between versions. Bug reports and feedback help a lot (see Reporting a problem).

See the roadmap for what's planned next.

Requirements

• PipeWire 1.0 or newer, with pipewire-pulse and WirePlumber running (most current distributions use them already)
• gtkmm 4.12 or newer
• For the mic's filters: RNNoise, the LADSPA SDK and LSP plugins, as LADSPA plugins

Installation

Arch Linux

WaveMix isn't on the AUR yet. Until it is, build the package from this repository:

git clone https://github.com/ChromieVT/wavemix.git
cd wavemix
makepkg -si

From source

You'll also need Meson 1.1+, a C++20 compiler (GCC 11+ or Clang 14+), libpulse, GLib 2.70+, gdk-pixbuf and nlohmann/json 3.10+.

meson setup build --prefix=/usr
meson compile -C build
sudo meson install -C build

Using it with OBS

Tip

Make WaveMix OBS's global audio (Settings → Audio), so every scene gets it automatically, with no sources to add or keep track of.

Global Audio Device	WaveMix Device
Desktop Audio	WaveMix Stream Mix
Desktop Audio 2 (VOD track, if you use the VOD Mix)	WaveMix VOD Mix
Mic/Auxiliary Audio	WaveMix Mic

Reporting a problem

Run wavemix --bug-report > wavemix-report.txt (or ☰ → Save a bug report… in the window) and attach the file to a new issue. Your home folder is hidden in it.
