Extract audio
- Category: Middleware
What it is
Extracts audio from a video. Use it when recognition needs a separate audio file; Breath cut should take the video directly, so skip this node there.
This node grew out of the related Lab tools: wires in a blueprint replace the step-by-step clicks in the Lab, which makes it easy to reuse and to hand to an agent.
