What is Routling
Routling is an ASIO-first audio router for Windows that connects any audio source to any destination through a visual node graph.
Routling is an audio router for Windows. It takes audio from anywhere on your machine - a hardware interface, a specific application, the whole system, a DAW - and sends it anywhere else, through connections you draw yourself.

canvas-context-menuThe problem it solves#
Windows gives every application one output device and one input device. That is fine until you want:
- Your microphone in Discord and in OBS, at different volumes
- Game audio in your stream but not your Discord call
- A hardware synth processed through VST plugins, live, with no DAW open
- Music that automatically ducks when you speak
- Two applications sharing one audio interface that only allows one connection
Routling sits underneath all of this. You open one audio device as the engine's clock source, then build a graph of everything else on top.
How it works#
Everything on screen is a node - a source of audio, a destination, or something that processes audio in between. You draw connections between node ports. Audio flows along those connections in real time.
There is no fixed signal path and no channel strip. If you can draw the connection, the audio takes it.
What makes it ASIO-first#
Routling opens one primary device - an ASIO device - and runs its entire audio engine from that device's callback. ASIO is the low-latency driver standard used by professional audio interfaces, and driving everything from one ASIO clock is what keeps latency predictable.
Everything else - WASAPI devices, application capture, virtual devices - attaches as a secondary device and is synchronised to that primary clock. See Primary and Secondary Devices.
What you can route#
| Source | Node type |
|---|---|
| Hardware inputs on your ASIO interface | ASIO Channels |
| A single running application | App Capture and System Audio |
| Everything your PC plays | App Capture and System Audio |
| Other apps sending into Routling | Routling I/O |
| A DAW, over 16 channels | Virtual ASIO |
| WASAPI / MME / Kernel Streaming devices | Primary and Secondary Devices |
And to process audio on the way through:
| Processing | Node type |
|---|---|
| VST2 / VST3 plugin chains | FX Module |
| Automatic volume reduction on a trigger | Ducker |
| Manual level control on multiple paths | Volume Knob |
What it is not#
- Not a DAW. There is no timeline, no recording, no arrangement.
- Not a mixer surface. There are no channel strips or busses; there is a graph.
- Windows only. The engine uses Windows audio APIs directly.
