batch automated save compressed copy and export

I have multiple .aup Audacity audios in several folders. I want to make a batch task, so automatically:

  1. It saves compressed copies of all the projects. And
  2. It exports to .mp3 each of these projects.
    I tried using the “chains” but I can’t open “raw” files, any ideas how to achieve this? Thanks in advance.

Chains works on batches of audio files (like WAV) or the current project. It would be a feature request to apply a chain to multiple AUP project files.

By the way, compressed copy of project saves an OGG file per each track in the project, so it is lossy, unlike standard projects.
