Scripting Reference

This is an experiemental page, not linked to from anywhere, to list automation commands.

• Yes these are the same commands as in "Commands and Shortcuts", same as in the menus, just presented differently.
  • Presented in a format useful to people using Scripting or Chains.
  • Most of this page is automatically generated.

For some effects we have two description strings, one created in wiki and one created from a description in Audacity code. This table currently incorrectly gives the one from Audacity code priority. The wiki version is nearly always more comprehensive and up to date and should be used instead

The Align->Tracks submenu has bad Automation IDs which make them unusable. This should be corrected in Audacity.

Nyquist and some other effects do not show their parameters in this table (yet)

Some of the menu items pop up dialogs, making them ill-suited for automation

This table shows the items in the menus in the Automation branch. That branch is not yet merged in to master

The Automation IDs, parameters and defaults are all likely to change between versions.

Otherwise, opens the "Set Right Selection Boundary" dialog for adjusting the time position of the right-hand selection boundary. If there is no selection, moving the time digits forwards creates a selection starting at the former cursor position, and moving the time digits backwards provides a way to move the cursor backwards to an exact point.
