Automatically Mixing and Exporting Audio

In the below example, there are two tracks and a label track below them. I need the program to do the following automatically: Mix and render the tracks and then export the audio between labels into separate files.

You can try [u]Chain-batch proecessing[/u], but I don’t know it will do everything you want.

I’ve never done it, so if you need help maybe someone else can help. I rarely do the same thing twice and whatever I’m doing I could do 100 times manually before I could “program”, test and debug the “automation”.

I have tried to create a chain command, but I cannot see the Mix and Render function in the list of commands inside Chains.
