SoundScape

Free & open source · macOS 14+

Route every sound.
Your way.

SoundScape is a native node-based audio router for macOS. Capture your microphone, an application, or the entire system, process it through Audio Unit and VST3 plug-ins in real time, then monitor or record the result.

An open-source alternative for Audio Hijack-style workflows.

One graph. Every source, processor, and destination in view.

Visual routing

Your audio, as a graph.

Connect sources, processors, plug-ins, recorders, and outputs visually. Build a route once, see exactly where every signal goes, and change it without rewiring your entire macOS audio setup.

Real-time audio

Built for live audio.

Reduce system playback captured by your microphone with WebRTC AEC3 and automatic delay alignment, then continue processing the cleaned signal through the rest of the graph.

Automatic delay alignment keeps the playback reference synchronized with the microphone path.

Persistent flows

Set it once. Keep it running.

SoundScape stores flows locally and keeps active routes running when the dashboard is closed. Start or stop them from the main window or the menu bar.

  • Local SQLite projects
  • Persistent device and plug-in settings
  • Automatic device reconnection
  • Menu-bar controls
  • Background operation

Active flows remain easy to find, start, and stop.
