The Audio Mixer provides a centralized view of all audio-capable inputs in your project, including media inputs, microphones, and Audio Channel Strips. It presents these sources in a familiar mixer-style layout, making it easy to monitor levels, apply adjustments, and balance multiple signals in real time.
Unlike configuring audio directly from each input, the Audio Mixer brings everything together in one place, allowing you to quickly compare, tweak, and refine your mix.

Accessing the Audio Mixer
To open the Audio Mixer:
- Click the Audio Mixer button
in the scene preview toolbar. - Or select Layout -> Audio Mixer from the main menu.
- Or press the
Ctrl+Mto toggle between the Compositor and Audio Mixer layouts.
See Keyboard Shortcuts for more key combinations and tips.
Once enabled, the Audio Mixer will appear, showing one strip for each input.
Mixer Strips
Each strip in the Audio Mixer corresponds only to inputs capable of processing audio. Whenever you add a new audio-capable input, it is automatically added to the mixer view. This ensures the mixer always reflects the current state of your project's audio sources without requiring extra configuration.
The order of mixer strips always matches the order of your inputs in the Inputs & Scenes tab. To reorder strips in the Audio Mixer, simply reorder the inputs under the Inputs & Scenes tab — the mixer will update automatically.
To hide an audio strip from the Audio Mixer without disabling its audio, enable Hide in the Input's Audio options. Helpful for keeping the mixer uncluttered when dealing with many sources.
From each mixer strip, you can:
- Monitor levels via the VU-meter.
- Adjust Gain (volume) with the fader.
- Control Pan (stereo balance).
- Mute/Solo inputs.
- Enable Pre-Fader Listening (PFL) for monitoring.
- Adjust auxiliary sends to Audio Channel Strips. See Audio Channel Strip for more info.
These controls overlap with the Audio options available on each input, but the mixer presents them in a more traditional mixing interface. For advanced functions — such as rerouting audio to different stereo pairs or detailed configuration — you can either use the Channel Strip Inspector or directly from the input's Audio options.
Audio Channel Strips

An Audio Channel Strip is a virtual input that acts as an audio bus (or submix). Unlike other inputs, it has no source of its own—instead, it receives audio sent from other inputs in your project. This makes it useful for grouping multiple sources under one fader, creating independent monitor mixes, or setting up parallel processing workflows.
Audio Channel Strips appear in the mixer with the label "STRIP" and an orange waveform icon.
Sending audio to a Channel Strip:
- Click the Sel button on the Channel Strip you want to route audio to.
- The other strips will turn dark green and display send faders.
- Drag any input's send fader to set how much audio is sent to the Channel Strip. You can also use the Up and Down arrow keys on your keyboard for finer control.
- Click Sel again to exit routing mode.
For full details on creating and configuring Audio Channel Strips, see Audio Channel Strip.
Toggle input open/close
By clicking on the buttons at the top of each strip, you can toggle open/close the selected input in Inputs & Scenes.

| Add to scene | Adds the selected input to the currently active scene. |
| Delete virtual channel strip | Deletes the Audio Channel Strip from the project. |
| Reset channel strip | Resets all audio settings (volume, pan, mute, solo, sends, etc.) back to their default values. |
Warning Icons
Warning icons appear on mixer strips to alert you when an issue has occurred during operation.

| Icon | Description |
|---|---|
| Stop Icon | Indicates a critical problem occurred. Check the log for detailed information. |
| Warning Icon | Indicates a non-critical issue occurred. Hover over the icon to view a brief description, or check the log for more details. Click the icon to dismiss it from the UI. |
Channel Strip Inspector
The Channel Strip Inspector is a panel on the right side of the Audio Mixer. When you click on a mixer strip, the inspector updates to show that strip's controls and audio configuration.

From the Channel Strip Inspector, you can:
- Toggle Solo, PFL, and Mute buttons (only audible when Audio Preview is active), mirroring the controls on the strip and input itself.
- Trim level gain, stereo remapping, adjust delay, and advanced audio processing like
Mapping,Gate,Low Cut,EQ,Compressor, andLimiterprocessing.
See the Channel Strip Inspector for more information.
