Nodaro DocsCombine Audio
Join audio clips end to end into one file, in the order you choose, and trim each clip first. For narration, podcasts and dialogue made in several parts.
The Combine Audio node joins audio clips end to end into one file. Each connected clip becomes a segment, the segments play in the order you set, and you can trim each one before it is joined. To play clips at the same time instead, use Mix Audio.
When to use it
- Join the voiceover lines of several scenes into one narration track.
- Put an intro, a main part and an outro one after another.
- Join the parts of a long conversation made in several Text to Dialogue nodes.

Frequently asked questions
What is the difference between Combine Audio and Mix Audio?
Combine Audio plays the clips one after another in a single file. Mix Audio plays them at the same time, layered on top of each other, with a volume for each track.
How do I change the order of the clips?
Drag the segments in the settings panel. They play from top to bottom. A new connection is added at the end of the list.
Can I trim each clip before it is joined?
Yes. Each segment has its own Start (s) and End (s) fields. Leave them empty to use the whole clip.
