Audio
Manage audio sources, monitoring, per-scene controls, and built-in filters.
DualStream's audio system gives you per-source volume control, real-time monitoring, built-in filters, VOD track management, and per-scene audio customization — all integrated directly into the Inspector Panel.
Audio in DualStream
Audio is managed per-source, not in a separate mixer panel. When you select a source that has audio, the Inspector Panel → Audio tab shows its controls. The Master Volume Control in the Inspector Panel header is always visible, showing your two main audio channels.
Master Volume Control
The Master Volume section sits at the top of the Inspector Panel and displays two always-visible channels:
- Desktop Audio — Your system audio output
- Mic / Aux — Your primary microphone input
Each has a real-time level meter, mute button, and volume control.
Audio Monitoring (CUE)
Monitor any audio source in real time through your headphones:
- Select a source with audio.
- In the Inspector's audio section, toggle CUE on.
The monitoring device can be configured in Settings → General. Restart DualStream after changing the monitoring output device.
Adding Audio to Sources
Some sources (Display Capture, Browser, Media) can have audio tracks:
- Select the source.
- In the Inspector Panel, enable Add an audio track for the source.
Audio Source Types
| Source | Description |
|---|---|
| Audio Input | Microphones, audio interfaces, capture cards with audio input |
| Desktop Audio | System audio output (captures what you hear) |
| Audio File | Play audio files (music, sound effects, intros) as a source |
Per-Process Audio
When you add a Window Capture source, DualStream can automatically capture audio from that specific application using native WASAPI loopback. This means you get game audio isolated from your browser, music player, or other apps — no virtual audio cables needed.

Click MUTE on any track to silence it in your stream without removing it.

This can be toggled even while you're live.
Per-Scene Audio
Linked (Default)
Audio settings are shared across all scenes.
