Programming and Development Macros and Scripting
6

To get you started with Nyquist Macros:

  1. Create a new Audacity project containing 1 track
  2. Run this code in the Nyquist Prompt effect (https://manual.audacityteam.org/man/nyquist_prompt.html). The Nyquist Prompt is an easy way to test out short Nyquist scripts.
(aud-do "SelectAll:")
(aud-do "Duplicate:")
(print "Done")

If you wanted to create three tracks:

(aud-do "SelectAll:")
(aud-do "Duplicate:")
(aud-do "SelectTracks: Track=0 TrackCount=1 Mode=Set")
(aud-do "Duplicate:")
(print "Done")

You can also use loops:

(aud-do "SelectAll:") ;selects the track and time region

(dotimes (i 6)
  (aud-do-command "SelectTracks" :track 0 :trackcount 1 :mode "Set")
  (aud-do "Duplicate:"))

(print "Done")

There’s a good amount of documentation for Nyquist these days. See: https://forum.audacityteam.org/t/manuals-and-reference-material/32817/1
