Tips for Open-Source Sound Software Audacity: Use ‘Chains’ for Batch Processing

here on the Audacity wiki.

There are two related Chain commands in the File Menu called Edit Chains and Apply Chain. Look first at Edit Chains to determine if an existing Chain (Audacity only ships with one) will suit your needs or to create a new chain. Next, use Apply Chain to perform the action on your selected audio.

The two uses of Chains are for:

  • Batch processing (where many audio files are processed unattended with one or more effects then exported to a new file)
  • Effects automation (where the selected audio in the track or tracks in the current project is subjected to the same prescribed sequence of effects, and optionally, a file exported from the entire audio.)
  • Read more.
