Combine Audio
Concatenate multiple audio tracks end-to-end into a single file.
Overview
The Combine Audio node joins connected audio tracks sequentially — they play one after another in the configured order. Each segment can optionally be trimmed to a start and end time before it is appended. The output is a single combined audio file. For layering tracks on top of each other with volume control, use Mix Audio instead.
How it works
- Connect audio nodes to the Combine Audio node’s input. Each connection becomes a segment.
- Reorder segments by dragging them in the config panel — segments play top-to-bottom. New connections append to the end.
- Optionally set a Start (s) and End (s) on any segment to trim it before concatenation.
- The node returns the concatenated audio.
