Build, process, record, and route audio with a native visual graph for macOS.
SoundScape is a node-based audio workstation for routing audio between microphones, applications, the macOS system, effects, recorders, and hardware outputs. Build a flow visually, press Run Flow, and keep it running in the background or control it from the menu bar.
| Visual audio routing | Connect, branch, combine, move, copy, and edit nodes on an infinite canvas. |
| Application and system capture | Capture one application or all audio playing on macOS with ScreenCaptureKit. |
| AU and VST3 hosting | Discover installed effects, edit their parameters, embed native plug-in interfaces, and preserve plug-in state. |
| Realtime echo cancellation | WebRTC AEC3 removes system playback captured by the microphone with automatic delay and clock alignment. |
| Native processing | EQ, filters, compression, gain, balance, pan, mono/stereo conversion, and multi-input combining. |
| Recording and routing | Record WAV or CAF files, route to multiple outputs, and select concrete Core Audio devices. |
| Persistent flows | Projects, node layouts, settings, and plug-in state are stored locally in SQLite. |
| Background operation | Flows continue when the dashboard is closed and remain available from the menu bar. |
SoundScape discovers installed AU Effect and Music Effect components through the native macOS Audio Unit registry. AU parameters and custom interfaces are shown directly in the node inspector, and their state is restored with the flow.
VST3 effects are discovered in the standard user, system, network, and bundled plug-in locations:
~/Library/Audio/Plug-Ins/VST3/Library/Audio/Plug-Ins/VST3/Network/Library/Audio/Plug-Ins/VST3SoundScape.app/Contents/VST3
SoundScape hosts realtime audio processing, parameters, program state, bypass, and compatible native VST3 editor views.
Third-party plug-ins currently run inside the SoundScape process. A broken or incompatible plug-in can therefore affect the application, so save important work before testing a new plug-in.

Download SoundScape.dmg from the
latest release, open it,
and drag SoundScape onto the Applications shortcut.
SoundScape requires:
- macOS 14 or newer
- Microphone access for Input Device nodes
- Screen & System Audio Recording access for application or system capture
Development builds are ad-hoc signed. macOS can request permissions again when the executable is rebuilt because its code signature changes.
Open Package.swift in Xcode and run the SoundScape executable target, or use
Swift Package Manager:
git clone https://github.com/GR0SST/SoundScape.git
cd SoundScape
swift run SoundScapeRequirements:
- Xcode with the macOS SDK
- Swift 6 toolchain
- macOS 14 or newer
