What it does
defEars creates clean audio lanes for Windows. Route any source — a mic, app, or browser — into a defEars Input, then pipe that signal out to OBS, Discord, a recorder, or your monitors.

A virtual cable does not play audio by itself. It routes audio between endpoints.
The six buses
Each bus exposes a paired Input and Output endpoint. In Windows audio tools, each endpoint appears as a stable named device.

Six buses · twelve endpoints · zero chaos
Built for creator routing
A1–F6 gives you six lanes for your signal stack — clean separation for the setups creators actually run.
Discord voice routing
Send your mic to Discord on one bus while keeping game audio on another — no more shared loops.
OBS scene audio control
Split mic, music, browser, and chat into separate buses so each OBS scene can mix exactly what it needs.
Browser audio isolation
Pipe a single browser tab into its own bus for recording or streaming without capturing the whole desktop.
Microphone monitoring
Monitor your own mic through a dedicated bus to catch clipping and noise before it hits the stream.
Dual-account / dual-app
Run two Discord accounts or two browsers and keep each one's audio on its own lane. No crosstalk.
Audio Repeater chains
Stack repeaters across buses to build monitoring chains, submixes, and parallel recording feeds.
Clean testing lanes
Reserve a bus for stream tests and dry runs so experiments never bleed into your live mix.
Setup, in plain English
A virtual cable doesn't play audio — it routes audio between endpoints. Here's a two-Repeater example using the D4 bus.
1
Repeater 1 — Mic into the cable
Wave in
Headset Microphone
Wave out
defEars D4 Input (VAC)
2
Repeater 2 — Cable back to speakers
Wave in
defEars D4 Output (VAC)
Wave out
Headset / Speakers
Remember: the cable itself is silent. Repeater 1 pushes your mic into the D4 bus; Repeater 2 pulls D4 back out to your headphones. Point OBS or Discord at defEars D4 Output (VAC) to capture that lane.
