Combine 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.

Quick start

Add the node

Press Tab on the canvas and choose Audio › Edit Audio › Combine Audio.

Connect the clips

Wire each audio node into the Audio input. Each connection becomes a segment, and a new connection is added at the end.

Set the order and the trims

Open the settings panel. Drag the segments into order; they play from top to bottom. To trim a segment, set its Start (s) and End (s).

Run it

Click Run on the node. The joined audio appears on the node with a player.
